By 2050, the EU aims to reduce its greenhouse gas emissions by 80%-95% compared with 1990 levels. New objectives up to 2030 provide for a 40% reduction of GHG emissions and an increase of 27% for renewables and energy efficiency. The aim of this work is twofold. Firstly, we present the inventory data of the greenhouse gas emissions, final energy consumption, share of renewable energy, ISO 14001, EMAS and ISO 50001 certifications in 2015 for the EU-28 member states. Then, we identify the current level achieved by the EU and by individual countries compared to the 2020 targets. Secondly, we find a correspondence between the increasing number of certified companies and the good results relating to the mitigation measures. The regulatory obligations and the growing awareness about climate change led companies to voluntarily adopting systems of environmental management and/or energy management, because they generate a series of benefits such as the improving of image return, revenues and levels of competitiveness.

Building upon the advantages that social network approach can predict performance in short investigation periods, this study develops a conceptual and novel framework to predict patent value through analysing patent citations network structural indicators. Our proposed approach helps alleviate truncation problems suffered by existing patent evaluation methods. Testable propositions are also offered. This study contributes to patent economics literature and research fields that would benefit from a more accurate measure of valuable technological inventions. The proposed approach also has practical and commercial values to research institutes and industrial firms. Journal: Int.

The core objective of this research was to examine the performance of the three operators in Jordan. It was found that the national telecommunications market is intensely competitive, and the three predominant operators have varying quality of service in numerous areas. Zain and Orange draw on their international leverage and capital to maintain market share, but the best technical and customer support value is offered by the later market entrant, Umniah, in terms of higher speed internet and better customer service. All firms benefit from high-quality human resources, and face similar challenges in terms of inhibitive taxes on prepaid tariffs and the stringent regulation of the Telecommunications Regulatory Commission.

The term 'transaction attractiveness' is offered by the authors as a general criterion of choice. The authors offer a framework for the analysis of transaction attractiveness on the basis of evaluation of the return on transaction costs (ROTC) index. The transaction attractiveness method includes the evaluation of the indexes of transaction costs, the indexes of general financial performance, and ROTC index. The methodology presented in the paper is based on a generalisation of the ideas about the transactions and transaction costs of the firm and specified for the accounting system of Ukraine (Western Europe). The factual implementation of the framework was provided at the Ukrainian enterprise and positively affected decisions of the distribution systems. Journal: Int.

The unanticipated component of the monetary policy is extracted by using changes in the three-month Euribor futures rate immediately after the ECB meetings. Our results show that monetary policy surprises from the ECB, when significant, exert a strong influence on yield spread returns and volatilities. The effects of ECB news announcement surprises on the debt markets differ substantially across PIIGS and non-PIIGS countries. It is important to note that the persistence of volatility is clear across all samples and it shown by the significance and the positive sign of associated coefficients. Journal: Int.
