At 2015 Conferences of Parties (COP 21), the world has committed to achieving net zero emissions by the second half of this century. Therefore, one of the strategies in the transport sector is the adoption of electric vehicles (EVs) and the use of biofuel in land transport. However, several key factors that influence the emissions across the entire life cycle of both EVs and internal combustion engine (ICE) vehicles, including fuel consumption, vehicle types, vehicle kilometer of travel (VKT), vehicle production process, and end-of-life disposal. This study aims to calculate and compare the Life Cycle Assessment (LCA) of ICE and EV vehicles for both passenger cars and motorcycles in five key countries in Association of Southeast Asian Nations (ASEAN): namely Indonesia, Malaysia, Thailand, the Philippines, and Viet Nam. The findings found that ICE vehicles produce a higher Greenhouse Gas (GHG) emissions than EV for both passenger cars and motorcycles in five ASEAN countries. EV with better energy conversion efficiency can help reduce GHG emission for road transport sector.

The power and energy potential for the candidate sites were evaluated using flow and power duration curves. The results demonstrate that the TRB has potential for small hydropower development, with twenty-four sites along the Tano River having a firm energy potential ranging from 4.6 to 46.4 GWh.

Meanwhile, rapid industrialization is expected to increase energy demand, fossil fuel usage, CO₂ emissions, and atmospheric pollutant emissions in the region. Therefore, this study presents the direction of climate change response in Southeast Asia by analyzing the outlook of CO₂ emissions and their contributing factors. This study targets the Association of Southeast Asian Nations (ASEAN), which comprises Brunei Darussalam, Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam. For a comprehensive analysis of the CO₂ emissions outlook and its contributing factors, these ASEAN countries were compared with four Northeast Asian countries, namely, South Korea, Japan, China, and Mongolia. Under the Shared Socioeconomic Pathway (SSP) scenarios adopted in the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, specifically SSP1, SSP2, and SSP5, the proportion of CO₂ emissions attributable to the 10 ASEAN countries in comparison to Northeast Asian countries is projected to gradually increase until 2100. The primary contributors to CO₂ emissions in Southeast Asia are economic factors, with carbon intensity emerging as the most sensitive to variations depending on the scenario. Thus, attention is drawn to the energy transition in Southeast Asia, with a particular focus on increasing renewable energy as a means of reducing future CO₂ emissions. The renewable energy share in total energy demand for the region is projected to fall short of global expectations, particularly lagging behind the global growth rate. There is an urgent need for comprehensive research, robust investigation, and a solid policy framework to address this shortfall and facilitate the transition, as it remains a pivotal agenda.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"86 ","pages":"Article 101721"},"PeriodicalIF":4.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We introduce the Clean Energy Access Prioritiser, an open-source tool designed to guide decision-making for clean energy interventions and investments.

The Clean Energy Access Prioritiser allows stakeholders to identify priority areas for clean energy projects through an integrated spatial planning approach. It combines a suite of 25 variables to evaluate areas most and least suitable for investment—hot and cold spots—based on user-defined priorities, using a 5 km grid. As an instrument for strategic planning, the Clean Energy Access Prioritiser holds value for a range of actors involved in energy development.

The rice sector leads in potential thermal energy and total mass, offering a substantial resource for renewable energy. The rice sector is also the largest contributor to CO₂ emissions in Guyana across all combustion levels, emitting over five times more CO₂ than the forest sector and over ten times more than the coconut sector at 100 % combustion.
