Assessing the energy efficiency of fossil fuel in ASEAN

The world's industries, transportation systems, and households rely heavily on fossil fuels despite their limited availability high carbon content. Therefore, it is of the utmost importance to improve fuel energy efficiency in order facilitate shift towards a sustainable system with reduced greenhouse gas emissions. This paper employs slacks-based measure network data envelopment analysis model undesirable outputs assess efficiencies Association Southeast Asian Nations (ASEAN) countries during span seven years, specifically from 2015 2021. inclusion this study important because allows for more realistic assessment by considering factors like CO2 emissions, which are outcomes associated use. datasets utilised sourced U.S. Energy Information Administration open website Our World Data. Based findings, can be observed that Singapore Philippines have demonstrated outstanding performance maximising utilisation fuels. In contrast, Myanmar exhibits lowest level analysis. By identifying top-performing terms efficiency, possible implement measures boost under-performing countries. achieved through promotion adoption cleaner alternatives, renewable sources exhibit low or negligible footprint. These findings offer significant contributions policymakers exploring usage, environmental stewardship, formulation execution comprehensive strategies aim mitigate dioxide emissions arising consumption ASEAN region.
