Lightweight and prefabricated construction as a path to energy efficient buildings: thermal design and execution challenges
by Eduardo Roque, Rui Oliveira, Ricardo Almeida, Romeu Vicente, António Figueiredo
Abstract: Energy efficient buildings start with a building design stage based on a strong background in building physics and construction technology. Traditionally, in southern European countries, massive construction solutions have always been associated with better thermal performance and more suited to easily comply with different performance and construction code criteria. However, lightweight construction systems have the potential to achieve clear benefits over traditional heavyweight construction. The market share of lightweight construction systems, from steel to timber, has grown significantly in the last two decades in countries that traditionally do not have strong background and workmanship on this construction type. Thus, two case studies were detailed presented, combining lightweight construction systems and Passive House concept, with the goals of energy efficiency and thermal comfort. The results highlight the advantages of these systems both from an economical (cost-efficiency and speed of construction) and environmental point of view (recycling, waste production and reuse).
Some drawbacks of lightweight building solutions have been pointed out, from low thermal inertia, overheating, airtightness, thermal bridging (building connections and assembly), higher susceptibility to moisture transfer, shading control, etc. Due to the possible low thermal inertia of this constructive technology, a new wall solution incorporating phase change materials was tested and thermally characterised. This solution could be applied in lightweight constructions, enhancing their energy efficiency and thermal inertia, further promoting the sustainability of these building solutions. In fact, all these issues have been overcome and are highly addressable in the design stage and considered in the latest developments on lightweight construction building systems.

The Effect of Awareness, Knowledge and Cost on Intention to Adopt Green Building Practices
by Redhwan Mohammed Saleh, Marhana Mohamed Anuar, Abdullah Al Swidi, Khatijah Omar
Abstract: Addressing the threats of climate change has become one of the worlds major challenges. More than 36 billion tonnes of carbon dioxide emissions have been recorded recently and the construction industry has been identified as one of the culprits in the worsening of climate change phenomena. Previous studies have revealed that conventional construction procedures are having a major impact on the environment. In light of these circumstances, this study examines the relationship among some influential and environmental factors including awareness of environmental issues, knowledge of green practices, cost of green materials, subjective norms, attitudes, perceived behavioural control and intention to adopt green building practices in Qatar. The data were collected from 378 engineers using a survey method and were analysed using PLS-SEM. The findings confirmed that significant relationships exist among all variables except for the effect of perceived behaviour control on intention to adopt green building practices. This study provides valuable insights that may help decision makers to plan for strategies to increase the adoption of green building practices among construction companies.
Keywords: Awareness of Environmental Issues; Knowledge of Green Practices; Cost of Green Materials; Intention to adopt Green Building Practices; Theory of Planned Behaviour.
Re-examining sustainable development in Europe: a Data Envelopment Approach
by Tihana Škrinjarić
Abstract: Sustainable development is a widely known concept in public and academic circles and in macroeconomic policy as well. This study applies Data Envelopment Analysis to 37 European countries for the period 2004-2016 in order to evaluate sustainable development objectively. The model uses GDP (Gross Domestic Product) per capita as desirable output, CO2 emissions and Gini Index as undesirable outputs and 3 input variables: unemployment rate, fixed capital formation and energy consumption. In that way all 3 pillars of sustainable development are included in the analysis. This is the first comprehensive analysis of European countries carried out with this methodology. Several model specifications are observed, in order to check for robustness of results and rankings. The results indicate that those countries which are already highly ranked by existing world indices (such as the United Nations and similar organizations) are ranked similarly in the empirical results of this research. Moreover, the most inefficient countries have shown an increase in sustainable development efficiency score over the observed period.
Keywords: sustainable development; data envelopment analysis; performance; undesirable output.
Prospect of Clean Coal for Sustainable Energy Mix in Malaysia
by Siti Fatihah Salleh, Abul Quasem Al Amin, Tuan Ab Rashid Tuan Abdullah
Abstract: This study evaluates the current energy diversification policy in Malaysia and proposes clean coal as an alternative to address the environmental issues and economic sustainability concerns in the power generation sector. In order to clearly picture the competitiveness of the proposed alternative, this study explored two scenarios, namely Scenario a and Scenario b. The former scenario acts as a baseline, where the conventional coal is consumed for power generation, while the latter scenario looks at the prospect of substituting the conventional coal with clean coal by 5%, 10% and 15%. Mixed with four other energy sources specified in the Five-fuel Diversification Strategy for power generation, the total amount of GHG that would be generated is estimated for both scenarios. It was found that the substitution approach could reduce the greenhouse gas (GHG) emission significantly up to 63%, from 823,498 million tones (Mt) by the year 2020. The findings highlight the potential of clean coal as a healthy alternative in reaching the Intended Nationally Determined Contribution (INDC)s target on GHG emission reduction. The results would lessen the gap between the GHG mitigation potential and the INDC target and would aid the formulation of effective energy strategy for power generation in Malaysia.

Mechanisms used by chemical manufacturing firms to promote green skills among employees: A case study in Malaysia
by J.S. Keshminder, Chuah Soo Cheng
Abstract: Threats imposed by climate change have raised the demand for green skills. Firms that provide green skills to their employees are touted to respond quickly to green policies and develop the capabilities to implement superior strategies to mitigate climate change. This study seeks to explore the mechanisms used by manufacturing firms to promote green skills among their employees. A case study approach using semi-structured interviews was deployed to explore these mechanisms in six large chemical manufacturing firms. The results indicate that collective effort, self-realization and continuous awareness were the three main mechanisms used by firms to promote green skills among their employees. Firms actively engage employees from every level of management together to upgrade their skills. Pay raise and promotion are used as an incentive by firms to encourage the employees to obtain green skills. This study proposes a green skills development mechanism for policy makers and managers to nurture and invigorate green skills among employees.

Sustainability of Marine Park Ecotourism in Malaysia: Predicting Environmentally Responsible Behaviour among Millennial Tourist
by Siti Intan Nurdiana Wong Abdullah, Zaiton Samdin, Jo Ann Ho, Siew Imm Ng, Kit Teng Phuah
Abstract: Promoting environmentally responsible behaviours in ecotourism destinations such as marine park islands has become an important strategy because of growing concern about global depletion of natural environmental resources, but few studies have been able to provide a comprehensive explanation of how the negative impact of mass tourism, especially of the millennial generation, can be mitigated. Hence the aim of this study was to examine the various antecedents of environmentally responsible behaviour among millennial tourists by proposing an extended model of environmentally responsible behaviour. Cross-sectional data from 386 cases were analysed using structural equation modelling and the results indicate that image of the destination, environmental attitude, knowledge and consumption values have a positive influence on behavioural intentions. Millennial tourists image of their destination and sound knowledge of conservation techniques turned out to be the main influences on intention to behave responsibly, with attitude and consumption values playing only a minor role. This study also confirms that intention is a strong precursor of behaviour. As tourism is part of the global experience economy, this paper suggests that to encourage millennial tourists to behave more responsibly, it would be useful to provide educational programmes and bold images that carry strong message at ecotourism sites in order to promote an emotional attachment to the natural environment, as well as practising more ethical and informative green marketing campaigns.

Religion and pro-environmental behaviour: A comparative analysis towards environmental protection
by Abdullah Mohammad Syafiq, J.S. Keshminder
Abstract: Faith factors strongly influence pro-environmental behaviours toward proactively solving environmental problems. This paper investigates different faith traditions and their link to the concept of environmental protection rooted within the major religions in Malaysia. In addition to a systematic literature review, data were collected using a cross-sectional qualitative study based on interviews with religious experts in Islam, Christianity, Buddhism and Hinduism. The study found that the religions of Islam, Buddhism, Christianity and Hinduism strictly prohibit the mismanagement of the environment. These religions dictate that one of the core responsibilities of humans is to act as caretaker of the Earth and its population. These religions are also believed to restore faith in protecting the environment and have the potential to be an effective medium to promote pro-environmental behaviour. This study proposes that the Malaysian Government integrate the element of religion in environmental policies that are used to nurture pro-environmental behaviour. Major mediums, such as education and media that are used to promote environmental awareness, should use religion as an element to heighten pro-environmental behaviour in order to cultivate sustainable communities.
Keywords: Religion; pro-environmental behaviour; sustainable communities; environment; Malaysia.
Redefining the value proposition through Green Promotions and Green Corporate Image in the era of Industrial Revolution 4.0 (I.R. 4.0) : A study of Gen Y Green Consumers in Malaysia
by Vathana Bathmanathan, Jegatheesan Rajadurai
Abstract: Industrial Revolution 4 (IR 4.0) is shaping the future of purchasing behavior due to the increasing influence of digital disruption. Digital disruption (DD) ends conventional business structures and believes the new frontier affecting the business value proposition. This leads to the creation of new business ventures, networks and alliances. With this background, this study analyzed the relationship between Green Promotion (GP) and Gen Y Green Purchasing Decision (GPD) in Malaysia. It also aimed to incorporate a new strategy by introducing green corporate image as a variable to identify if it mediates the relationship between GP and GPD. Finally, this study explored the items of Green Promotion (GP) and Green Corporate Image (GCI) as viewed by the Gen Y consumers in the current business context. The study was conducted in two phases. Firstly, a qualitative approach used to extract the current themes in green marketing by interviewing 5 focus groups to refine the questionnaire so that it aligned with the current scenario. Secondly, interviewing data analyzed by using Structural Equation Modelling (SEM) to understand better whether i) green promotion positively and significantly influence the Gen Y Green purchasing decision, ii) green promotion positively and significantly influences Gen Ys perception of green corporate image, and iii) green corporate image mediates the relationship between green promotion and green purchasing decision in the context of Gen Y consumers. The study findings are both important and useful for manufacturers to understand their promotional strategies for the adoption of digital process further. This study would also assist policymakers to meet the 11th Malaysia Plan with Industrial Revolution 4 (IR 4.0) goals.

Staircase Evacuation for Public Multi-Storey Housing in Malaysia
by Nurul Liyana Hanapi, Sabarinah Sh Ahmad, Norhati Ibrahim, Azli Abd Razak
Abstract: There has been some concern about the evacuation safety aspects in older affordable multi-storey housing for the lower income group in Malaysia as the number of occupants has been increasing over the years. The multi-storey public housing type has multiplied albeit with its own challenges. This paper aims to study the effects of increased occupancy towards evacuation duration in public multi-storey housing in Malaysia, to gain a better understanding of evacuation safety. The research methodology is through a simulation study using Pathfinder software. This paper focuses on the evacuation process in public multi-storey housing, mainly on the staircase availability and location, in relation to the increasing number of evacuees. The data analysed include the duration taken by occupants to reach safety and their movement patterns during evacuation through a simulation study. A 17-storey residential building is modelled in the programme and the effects of staircases with varied availability and locations on the evacuees are tested. Nine scenarios are considered. Results show that higher number of occupancies and non-availability of the staircase could prolong the evacuation. Moreover, the location of staircases does not influence the evacuation time but contributes significant changes to the movement of the evacuees.

Are Environmentally Responsible Behaviours Shaped by Environmental Facilitating Conditions and Antecedent of Attitudes? The Case of Perak in Malaysia
by Ai Na Seow, Yuen Onn Choong, Lin Sea Lau, Chee Keong Choong, Chun T'ing Loh, You How Go, Suet Ling Ching, Kwang Jing Yii
Abstract: This research attempts to present the notion of understanding through the empirical studies on environmentally responsible behaviour for strategies development with an emphasis on the role of facilitating conditions. A total of 263 usable questionnaire responses were collected for data analysis. The major findings show that environmental concern and environmental knowledge are important for environmental attitude in order to cultivate the environmentally responsible behaviour among tourists. Conversely, environmental facilitating conditions are directly related to environmentally responsible behaviour instead of having the moderating effect on environmental attitude. This study contributed in reassuring the tourists participation in the environmentally responsible behaviour with commitment in environmental concerns and interest in knowledge towards environmental and sustainability issues while visiting natural sites.

A Comparative Requirement of Space Design: Green and Open Space Analysis
by Puziah Ahmad, Muhamad Sharrifullah Hashim, Alamah Misni, Siti Mazwin Kamaruddin
Abstract: Planning guideline is a document that governs the design process of our physical environment. It is important in ensuring urban spatial development to oversee whether that is healthy, safe, attractive, and economically viable. This study focused on studying a few sets of planning guidelines, namely for Selangor, Melaka, and Johor States in Malaysia. To have a good outcome, this study compared and analysed the open and green space requirements on the six elements for landuse development. An assessment of the guidelines was done using several variables, such as (i) the amount of open and green space required, (ii) vegetation characteristic, (iii) green space distribution and (iv) configuration. The study findings by the content analysis and ordinal scale assessment suggested that the existing planning guidelines have not been specific on the provision and design aspect for the open and green space. This study suggests some feasible motivations in planning for the enriched open green space guidelines.

by Mohamad Sufian Hasim, Mohd Khairul Anuar Jalil, Lilis Shereena Safiee, Ellemy Iskandar Khalid, Qi Jie Kwong
Abstract: Facilities Management (FM) has been recognised as one of the most important entities in supporting the goal of sustainability within organisations. Sustainability in FM practices is benefiting an organisation in achieving sustainable environmental, economic, and social improvement. Organisational performance towards sustainability has a significant relationship with the drivers, whether from internal or external sources. This study aimed to determine the factors within FM practices that could enhance sustainability practices in university organisations. To achieve the above aim, ten (10) face-to-face semi-structured interviews at all three South Australian Universities were administered to gather in-depth information involving Heads of Department and those at senior managerial level in the universitys FM department. The analysis has established ten (10) themes, and the most frequent factors in South Australian universities were pressures from stakeholders (28%) (i.e. from students and staff, or governments); economic benefit (26.5%) (i.e. business opportunity and cost reduction); commitment by top management (18%) (i.e. executive level, embedded in university strategic goal); and collaborations with other parties (7.5%) (i.e. local government, state government or private companies). The information gathered will help other organisations as prospects of lessons learned especially for universities in other countries.

Measurement of green industrial performance: an enhanced GIP index
by Jaime Moll De Alba, Valentin Todorov
Abstract: The green industrial performance (GIP) index provides a tool to analyse and compare the performance of economies in terms of green manufacturing. The demands for and expectations for sustainable development seem not matched with the existence of an analytical framework to measure how green the industrial sector of a given economy is. In this article, we introduce significant methodological improvements to the GIP index.
In previous research, we developed and tested a set of indicators covering the various facets of the green industrial performance of economies. We also introduced a composite index to rank economies according to their green industrial performance. In this article, we address some limitations of the index. To improve the non-satisfactory data coverage, we investigate alternative imputation methods. We also refine our list of green products; and test new outlier detection methods.
Keywords: Inclusive and sustainable development; composite index; green industry.
Alternative forms of sustainable development: The case of thermal tourism
by Stavroula Georgakopoulou, Vassiliki Delitheou
Abstract: Thermal tourism is a special form of providing tourist services at special facilities that use recognized thermal natural resources. Thermal tourism blooms in Europe with pioneer country Germany. There are 1,400 developed bathing sites in Europe, visited by millions of patients from all over the world. This industry employs about 750,000 people and has an annual turnover of approximately 45 billion euros. In Greece, thermal tourism is an important part of the countrys cultural heritage and not only because Greece is one of the richest countries in natural sources with excellent quality water. Despite the fact that Greece is the first country in Europe in the quality and uniqueness of natural thermal resources, its thermal tourism is declining. Furthermore, in this article, efforts will be made to identify the causes that contribute to the reduction of thermal tourism, as well as to draw some conclusions with a view to improving and sustaining the thermal tourism.

Quantitative Analysis of Sound Absorption Properties of Plants in Indoor Environment for Enabling Sustainable Practices
by Namrata Baruah, Satyaki Sarkar, Bimal Chandra Roy, Rajan Chandra Sinha
Abstract: This paper showcases the results of the sound attenuation properties of some plants with a soil substrate for use as green sound absorbers in an indoor space. The plants used in this experiment were needed to survive in an indoor environment, hence only tropical, thermophilic plants which could grow in high humidity and warm temperatures with indirect sunlight were selected. An Impedance tube of 100mm dia. was used to calculate the direct incidence acoustic absorption coefficient of the plants and larger samples were tested within a reverberation chamber. The soil substrate used was a high porosity and low-density sample of perlite and coconut fibers. The results show that Ferns and Baby Tears were good absorbers along with the soil substrate, whereas Begonia was a better absorber at the lower and higher frequencies. The decibel drop by the fern with soil substrate is the highest with a decrease of frequency and the lowest is by Green Ivy which is due to morphological conditions.

Strategically-framed environmental disclosure index: A Measurement Approach of Malaysian Public Listed Companies Corporate Environmental Reporting Practices.
by Amar Hisham Jaaffar, Bakhtiar Alrazi, Say Keat Ooi, Amanuddin Shamsuddin
Abstract: This study aims to measure the corporate environmental reporting (CER) practices of Malaysian environmentally sensitive public listed companies based on measurement approach named strategically-framed environmental disclosure index. The content analysis technique based on a measurement index related to firms environmental strategies has been employed. The CER practices of 209 Malaysian environmentally sensitive public listed companies are examined for the years 2010 and 2014. Results suggest that there are three types of firm behaviour in CER in response to institutional pressures: (1) 'negative deviance' (i.e. non-compliance environmental strategies leading to no quality environmental disclosures), (2) 'conformance (i.e. compliance environmental strategies leading to low quality environmental disclosures) and (3) 'positive deviance' (beyond-compliance or proactive environmental strategies leading to high quality environmental disclosures). This index shed light whether the Environmental Social Governance (ESG) practice in Malaysian and global context as a deviance or normative behaviour. Moreover this study identified whether mandatory reporting requirement force firm to actually improve environmental performance concurrently with pro-environmental policies or just as their greenwashing mechanism.
Keywords: Corporate Environmental Reporting; Strategically-framed environmental disclosure index; Neo-Institutional Theory; Positive Organizational Scholarship; Environmental; Social and Governance (ESG).
Evaluating the Impact of Implementing Minimum Energy Performance Standards (MEPS) Appliance Regulation in Malaysia
by Siti Fatihah Salleh, Mohd Eqwan Mohd Roslan, Aishah Mohd Isa
Abstract: One of Malaysias key strategies to promote efficient use of energy is by implementing the Minimum Energy Performance Standards (MEPS). Under this regulation, five common household appliances (air conditioner, refrigerator, fan, television, and lamp) must comply with MEPS requirement in order to be sold in Malaysian market. This study collected sales data from major suppliers to estimate the annual sales volume of MEPS-compliant appliances from 2013 to 2015. The sales estimates were used to determine the total electricity consumption and saving during the same time period. The study found that the local market is already saturated with 5-star rated televisions and fans in 2015. Meanwhile, the lamp market proportion is dominated by compact fluorescent lamps (CFL) with efficacy range from 50 to 55 lumens/watt. By the end of 2015, the total cumulative annual electricity saving gained after MEPS implementation is 2,685 GWh, which translates to a total annual cost saving of MYR 850 million and fossil carbon emission reduction of 1,726 ktCO2eq. By identifying and quantifying the multiple impacts of MEPS implementation in Malaysia, this work not only demonstrates the effectiveness of the current initiative, but also motivates higher uptake of energy efficiency interventions in developing countries to unlock more opportunity in the future.

ANALYSIS OF OPTIMAL OPTIONS FOR CO2 EMISSIONS REDUCTION IN MALAYSIAN TRANSPORTATION SECTOR
by SITI INDATI MUSTAPA, Siti Fatihah Salleh
Abstract: The rapid development of the transport sector has caused tremendous pressures on energy consumption and CO2 emission. Energy use for the road transport sector is growing faster, but the scope for substituting towards low carbon fuels is rather limited. As the increase in CO2 emissions has become an important global issue, many countries have put up a voluntary target of reducing its CO2 emissions. Similarly, Malaysia has set a target to reduce the intensity by up to 45% by 2030 based on its 2005 levels. This has led to strong interest in how the CO2 emissions in this sector can optimally reduce. This paper therefore looks at minimising the CO2 emissions from the transportation sector. A linear programming model is applied to model the present situation in Malaysia. Sensitivity analysis is applied to investigate the effects of mitigation scenarios such as low carbon fuels, fuel efficiency improvement, travel demand management, and integrated mitigation strategies on the CO2 emissions. The results demonstrated that the optimal CO2 emissions in the road transport sector could reduce by only 2.8% (1.14 Mtons) in a year, which far below the desired emissions reduction. However, the sensitivity analysis results demonstrated that a reduction of up to 40% (16.44 Mtons) can be achieved from integrated mitigation measures, which enable Malaysia to hit reduction far beyond its target. The outcome of this study proved that intensifying ongoing efforts and stringent policies to promote efficient fuel use and investment in green technology could assist the country in its quest to achieve the intended CO2 emissions reduction.

Development of Natural Fibre for Environmental and Sustainable Advancement
by A. Atiqah, M. N. M. Ansari, M. M. M. Zahidi Zahidi, S. Begum, Z. Yahya, S. A. A. Alkhadher
Abstract: The increasing attention on renewable resources for a sustainable environment has led to the expansion in the development of high-performance products made from natural resources. Natural fibres that are diffused in the environment in abundance are economical, making this characteristic a value-added engineering, as they exhibit lower cost and can produce lighter composites, as compared to the existing fibreglass reinforced polymer composites. In this study, the involvement of kenaf fibre in chemical treatment on morphological and mechanical properties of the thermoset polyurethane (PU)-(PUKf) composites was firstly proposed and trialed. The results of chemical treatment on kenaf fibre highlight the improvement on the impact strength although the hardness of kenaf composites is reduced. This is compared with different samples, which are pure thermoset PU and kenaf fibre without chemical treatment. Overall, the developments of natural fibre in engineering and energy sectors could significantly enhance the reduction of solid waste and environmental pollution.

Sustainable Procurement and Corporate Sustainability Performance: The Moderating Role of Organization Age
by Maryam Jamilah Asha'ari, Salina Daud
Abstract: The chemical manufacturing industry is one of the main contributors to the Malaysian economy. The chemical manufacturing industry has been reported to have sustainability issues which may affect the sustainability of the nation if proper green practices have not been taken by the industry. This paper aims to study the effects of sustainable procurement on corporate sustainability performance with the moderating role of organization age. Drawing data from 130 Malaysian chemical manufacturing organizations, the model studies the moderating role of organization age on sustainable procurement and the corporate sustainability performance of the organizations. Partial Least Square (PLS) analysis is used in this study in order to analyse the data and the multistage sampling technique has also been used in this study. The results show that there is a positive relationship between sustainable procurement and corporate sustainability performance. The results also suggest that organization age does not moderate the effect of sustainable procurement on corporate sustainability performance where it contributes to new finding in this research area. The findings could help employees and policy makers to counter the sustainability challenges they face in chemical manufacturing organization.

Recycling and Sustainable Environmental Practices of Household Tea Waste
by A. Atiqah, M. N. M. Ansari, R. Keresahnia, S. A. A. Alkhadher
Abstract: Tea wastes contain a group of important organic substances disposed of in a considerable amount to the environment without any treatment after the preparation of tea. Generally, uncontrolled release of these wastes has increased environmental concern mainly to the aquatic environment in recent years. In this study, an experiment of tea waste green composites was outlined to provide more knowledge and findings in utilising the tea waste as reinforcement. The current experimental investigation focuses mainly on the mechanical and characterisation of poly (lactic acid) (PLA) filled with household tea wastes (TW) green composites. The morphology properties of PLA with tea waste composites were characterised using Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) methods. The results show that the addition of tea waste improved the mechanical properties of the composite, nevertheless the crystalline structure was reduced due to the presence of tea waste particles. The study findings highly recommended that tea wastes should be environmentally managed and recycled for better utilisation as an energy source or in other valuable application to reduce the impact on environmental pollution.

Clarifying the value relevance of voluntary carbon reporting: The case of Malaysian carbon-intensive industries
by Noor Raida Abd Rahman, Siti Zaleha Abdul Rasid, Rohaida Basiruddin
Abstract: This study aimed to empirically test the value relevance of voluntary carbon reporting (VCR) by Malaysian public listed companies operating in carbon-intensive industries from 2010 to 2016. Using panel data regression models, this study considered the impact of VCR from both, accounting and market-based perspectives. The quality of VCR is measured using the content analysis of disclosure indexes adapted from a list of disclosure items that were provided in various global warming, climate change, greenhouse gases, and carbon reporting guidelines, standards, and frameworks. The finding indicated that on average, the quality of VCR was still low compared to the overall potential score. The findings also revealed that VCR generates a negative relationship with return on assets (ROA) and earnings per share (EPS). Nevertheless, VCRQ does not influence return on equity and Tobins Q. This study has implications on both the policy and practice of organisations seeking to improve VCR practices.

Analysis of Urban Water Quality Trends for Effective Reservoir Sedimentation Management in Cameron Highland
by NURSHAHIRA MOHAMMAD NOH, Lariyah Mohd Sidek, Siti Humaira Haron, Amirah Hanim Mohd Puad, Zalilah Selamat, Azwin Zailti Abdul Razad, Chow Ming Fai
Abstract: Water quality in Cameron Highlands has significantly diminished due to agricultural activities. This research aims to analyze water quality in the urban and agricultural area by conducting water sampling and in situ analysis. Water Quality Index (WQI), Total Nitrogen (TN) and Total Phosphorus (TP) were calculated and compared among different areas. Results for WQI shows that water quality at W7 deteriorates at class IV (33.5) compared to class II for another agriculture area. Meanwhile, another results showed that the WQ_02_AG transported significantly higher (14.9 mg/L) loads of TN than the urban area, but the phosphorus load was considerably lower (1.58 mg/L). Results for the urban area are slightly polluted and unsuitable for recreational purpose. In agricultural areas, water quality deteriorates due to sediment transport and nutrient infusion caused by agricultural activities. Therefore, powerful agricultural management practices for effective reservoir sedimentation management as one of the non-structural measures are recommended.

Sustainability of textile waste-water management by using an integrated fuzzy AHP-TOPSIS method: A case study
by PUNYASLOKA PATTNAIK, Govind Sharan Dangayach
Abstract: The textile industry is quickly growing worldwide and has a universally beneficial effect on the economy. The waste-water generated with the growth of the textile industry can cause considerable health and environmental issues if it is not treated properly. Generally, physical, biological, and chemical processes are used independently or in combination to treat textile waste-water. The efficiency of any treatment process depends on the working criteria. In this paper, we implemented a new hybrid methodology based on the fuzzy analytic hierarchy process (FAHP) and fuzzy technique for order preference by similarity to ideal solution (FTOPSIS) to help workers in textile industries select the optimal waste-water treatment process. To illustrate how this hybrid methodology can be used to address the waste-water treatment problem, we conducted a case study involving 11 assessment criteria and four treatment process used in the textile industry in India. Comparative analysis indicated that the survey overall mean was slightly lower than the overall mean for selected companies in the treatment process.

The influence of environmental management accounting practices on environmental performance in small-medium manufacturing in Malaysia
by Rapiah Mohamed
Abstract: The purpose of this study is to investigate the influence of environmental management accounting (EMA) practices on environmental performance in the small-medium sized (SME) manufacturing sector. The empirical data was collected through structured questionnaires that were distributed to the managers. The study results reveal that physical EMA has the highest mean score compared to monetary EMA, however, unfortunately the EMA practice is not at an encouraging level in Malaysia. The regression results indicate that both types of EMA practices (monetary and physical) have a positive and significant effect on environmental performance. Thus, this study demonstrates the importance of EMA in enhancing environmental performance. The study results are valuable to policy makers, managers of manufacturing SMEs and other sectors to appreciate EMA practices. The study findings contribute to a growing body of literature on EMA within the Asian context, particularly, Malaysia. Finally, this study shed lights on the extent to which EMA tools has been used amongst manufacturing SMEs and provides a good foundation and framework for future studies.
Keywords: Environmental management accounting; environmental performance; and small-medium manufacturing; Malaysia.

Islamic Bankers Green Behaviour for the Growth of Green Banking in Malaysia
by Qaisar Ali, Shazia Parveen
Abstract: Rising concerns for environmental sustainability (ES) demand that Islamic finance converts its business model to ethical finance. The conversion of a business model is unattainable without employees positive attitudes and willingness to adopt the green banking approach. This study aims to promote ES implications for Islamic bankers and encourage Islamic banks to adopt a similar approach. The main objective is to explore green behaviours among Islamic bankers and the influence of these behaviours on green banking growth in Malaysia. Data were collected from 55 Islamic bankers using a survey questionnaire. The findings show that Islamic bankers inclusive green behaviour significantly influences green banking growth. All five types of green behaviours (e.g. conservation, work sustainability, avoiding harm, influencing others and taking initiative) have a significant positive impact on green banking growth. Regulators and policymakers may adopt these findings to develop green banking regulations in Malaysia and other locations with similar economic settings.

The Impact of Spatial Development on Water Pollution: A Comparative Assessment of River Water Quality in Two Municipalities in Malaysia
by Hamidi Ismail, Tuan Pah Rokiah Syed Hussain, Muhammad Subhan
Abstract: This study is aimed at understanding different level of pollution of the river water in two municipalities in Malaysia as a result of spatial development activities. Both municipalities represent the central and southern zones of Peninsular Malaysia which are prone to river water quality problems due to logging, land clearing and livestock farming. Frequency and trend analysis are applied to the data obtained from the Department of Environment (DOE) and measurement of the water quality in the field is conducted in both areas. The results show that the rivers in both municipalities are experiencing deterioration of water quality. The decline in the river water quality is closely related to human activities in urban space and the ineffective environmental management system by the government. The apparent environmental problems indicate that the present management system should be improved to create an urban ecosystem which is really capable of addressing the issues of river water pollution.

Climate change adaptation: a corrective policy framework in the Malaysian agricultural sector
by Rulia Akhtar, Muhammad Mehedi Masud, Abu Hanifa Md. Noman, Najneen Jabin, A. S. A. Ferdous Alam
Abstract: A corrective policy framework is essential for sustainable agricultural management. In order to put in place a corrective policy framework, it is necessary to know the socio-economic context of local farmers and their perception of climate change. Therefore, the main objective of this study is to explore their socio-economic status and general perception of climate change and to examine its impact on adaptation practices. To achieve the research objectives, data were collected using survey questionnaires and analyzed using statistical tools. The results show that most of the respondents between age range of 31-45 years in the sample size while 45 percent ha secondary education and 34 percent of the respondents monthly income between RM 2000- RM 4000. It has been found that approximately 76 per cent of farmers had heard about climate change. The results also revealed that socio-economic characteristics such as education, income, type of farmer, attitudes and awareness were positive and highly significant. It is hoped that the findings of this study would be useful for policymakers in designing an appropriate policy framework to raise awareness of how to reduce the impact of climate change in the agricultural sector.

THE ENVIRONMENTAL RESOURCE MANAGEMENT PARADOX IN AN IMPOVERISHED URBAN POPULATION: A CASE STUDY FROM MALAYSIA
by Md Wahid Murad, Md. Mahmudul Alam
Abstract: The poverty-environment nexus is still being debated since it came into light in the late 1980s. The extent of poverty and nature of environmental degradation make the debate further complex as researchers present their research outcomes, whether conceptual or empirical, based only on limited data and a number of assumptions. This study is such an attempt looking at the poverty-environment paradox from the perspective of an emerging country, i.e. Malaysia. Household solid wastes, if recycled, reused and source-reduced, are widely considered environmental resources as these practices are meant to protect the environment and increase peoples incomes or save costs especially for societys poorer people. To test the hypothesis that poverty is the root cause of environmental degradation or environmental degradation is the effect of poverty, this study assesses attitude and behavior of the urban poor with reference to solid waste management and their willingness to pay for an improved solid waste collection and disposal service in their residential areas. Primary data collected through a survey with urban poor residing in Kuala Lumpur and analytical methods including descriptive statistical technique, t-test of equality of means, one-way analysis-of-variance, Chi-square likelihood ratio test and multiple linear regression have been used to test the hypothesis and accomplish the objective. Empirical results nullify the null hypothesis, favoring the urban poor as their attitude and behavior are found to be environmentally sound and surprisingly ethical. Also, their monetary contribution, as measured through willingness to pay, for the objective of improving environmental conditions is considered to be good news for local governments, who could use this strategy in their efforts to improve the environment and reduce urban poverty. Policies and initiatives such as pro-poor waste management, community participation in waste management, integrating the informal sector into formal waste management avenues, public-private partnership in waste management, and raising awareness among the relevant stakeholders are considered crucial for reducing both the environmental degradation and urban poverty.

Sustainability of Malaysian Oil Palm: A Critical Review
by Halima Begum, A. S. A. Ferdous Alam, Abd. Hair Awang
Abstract: Despite some industrial disruption, palm oil is still among the strongest industry of Malaysia. This journey of excellence towards becoming the global leader is getting momentum by support from MPOB, a leader in palm oil research across the globe. This study is to assess the oil palm smallholder activities in Malaysia in order to ensure the sustainability to face the global challenges and competitions of the international markets. Thus, the industry is emerging not only as a dependable source of economic empowerment of the country, but also posing a serious threat towards
ecological and social balance due to unawareness of the sustainability issues. With their outstanding share, the industry has potential to lead the market in the near future, but in the way of expansion it must focus on the sustainability issues especially related to environment, economy and society, which can adversely or constructively influence the industry and its production.

Global Population Stabilization Policy and Declining Work-Age Population: A Threat to Global Economic Sustainability
by Md. Mahmudul Alam, Md. Wahid Murad, Rafiqul Islam Molla, Khondaker Mizanur Rahman, Taslima Rahman Khondaker
Abstract: Faced with an exponentially growing world population, what is required is a population stabilization policy to control the global fertility rates. This has implications for the working-age population in the future, and lead to a serious economic crisis. It is envisaged that by the year 2050 the work-age population will have seriously declined, but is still expected to look after an increasing dependent population. This paper argues that to maintain sustainable economic growth, and to support the associated technological advances in the future there will be demand for a larger labor force. It notes that the industrialized countries are now managing with migrant populations drawn mostly from high fertility but low-income countries. In the global context this is only a zero-sum game without increasing the stock of the worlds actual total labor force. Therefore, the world population needs to increase to meet the growing demand for a larger labor force in order to achieve economic sustainability. Since the earths population carrying capacity largely depends on advanced technology functioning well, to support societys lifestyle expectations, the world should not defer planned population growth.

Sustainability Practices Framework of the Palm Oil Milling Sub-Sector: A Literature Survey
by Halima Begum, Er Ah Choy, A. S. A. Ferdous Alam, Chamhuri Siwar, Suraiya Ishak
Abstract: A sustainable practices framework in accordance with environmental, economic, and social dimensions, is an important constituent of the palm oil milling sub-sector for its effective contribution to the national economy of Malaysia. A major threat to the palm oil mills is the adoption of a lower sustainability practices framework that can result in environmental degradation, low production, low prices of crude palm oil (CPO), and low labour costs, amongst others. The main objective of the study is to examine the sustainability practices framework of the palm oil mills in Malaysia, through a comprehensive literature survey. Therefore, the methodology for the framework was studied using public-domain journal articles found through electronic databases. The literature survey encompasses publications dating from 1987 to 2018. The findings of the study reveals that production rates and price of CPO are decreasing, although demand remains high. It suggests a further study of better national sustainable policies and standard for the palm oil mills via a primary survey.

Population ageing and energy consumption for sustainable development
by Nur A'mirah Mohd Yaziz, Azlina Abd.Aziz
Abstract: Population ageing has been acknowledged as a cause of the alteration in residential energy consumption pattern, which partly arises from the exit of the workforce from the labour market due to the retirement age limit, promoting a sedentary lifestyle. However, there is a lack of research exploring the shift in energy demand that specifically scrutinises the effect of population ageing on the consumption structure. In this context, the paper aims to investigate the relationship between residential electricity consumption and demographic indicators specific to labour force participation. This study uses a literature survey of household consumption structure, ageing labour force participation, and energy consumption factors, while the econometric approach is proposed to estimate the determinants. Based on the findings, this study supports the inclusion of the employment rate in expressing residential electricity consumption in the population ageing scenario. This paper ends with the development of a proposed model for future research work due to the economics of population ageing in energy.
