Energy Efficiency Improvements Could Boost Vietnam's GDP: UNDP Research

Research by the United Nations Development Programme (UNDP) indicates that improving energy efficiency could significantly boost Vietnam's Gross Domestic Product (GDP). The findings suggest that enhanced energy efficiency not only helps reduce energy consumption and emissions but also raises disposable incomes across all household groups. This highlights the potential for well-designed energy transition policies to deliver simultaneous economic, environmental, and social benefits. The research outcomes are derived from a range of policy scenarios tested using new analytical tools unveiled at a workshop in Hanoi. These tools are designed to support evidence-based policymaking, enabling Vietnamese policymakers to assess the effects of different energy-transition policies on economic growth, emissions, and the incomes of various household groups, including the most vulnerable. Central to these tools is a new Energy-focused Social Accounting Matrix (ESAM), a comprehensive economic dataset that maps the interconnections between production, energy use, household income, and emissions within a unified analytical framework. The ESAM was developed through a collaboration involving the Institute for Policy and Strategy Studies (IPSS), the University of Copenhagen, the General Statistics Office of Vietnam, and UNDP in Vietnam. The study also explored policy options that might involve more challenging economic and social trade-offs. For instance, modeling suggests that a carbon tax of US$15 per ton of carbon dioxide equivalent could reduce emissions by approximately 2.9% by increasing the relative cost of carbon-intensive activities. However, this could lead to a decline in GDP of around 0.8% and, without compensatory measures, a potential fall in household incomes across various income brackets. Ramla Khalidi, UNDP Resident Representative in Vietnam, emphasized the ESAM's value in helping policymakers evaluate the economic, social, and distributional impacts of energy transition policies. She noted that tools like the ESAM are crucial for understanding these trade-offs and designing policies that advance energy security, environmental sustainability, and, critically, equity. As Vietnam accelerates its transition towards a low-carbon economy, robust evidence and forward-looking policy analysis will be vital to ensure that growth, energy security, emissions reduction, and social inclusion progress together.
