Abstract: This study explores the transformative impact of conservation and eco-friendly technologies on two warehouse inventory, aiming to prevent product degradation and substantially reduce carbon emissions in greenhouse operations. The research underscores the urgent need for government-led carbon emission laws to address environmental and economic repercussions. With a focus on the proposed model, two key contributions emerge: 1) strategic investments in eco-friendly technologies and conservation methods for minimising carbon emissions and product degradation; 2) the application of preservation technology to curtail product deterioration. The comprehensive model integrates factors such as demand dynamics, pricing, stock, expiry dates, payment delays, and inflation, seeking optimal order quantities, cycle durations, and selling prices for profit maximisation. Validated and exemplified quantitatively, the model's efficacy is demonstrated, complemented by a thorough sensitivity analysis. This research not only advances inventory management practices but also advocates for environmentally sustainable strategies with direct financial implications.

Keywords: two warehouses inventory; price-stock and lifetime dependent demand; inflation; preservation technology; carbon emission.
