China’s Official Energy Finance in Emerging and Developing Economies
Evolving institutions, instruments and implications for clean energy transitions Global energy investment exceeded USD 3.3 trillion in 2025, but capital flows remain uneven. Emerging market and developing economies (EMDE) outside China attracted just 27% of total energy investment and 18% of clean energy spending, despite accounting for nearly two-thirds of the global population and the bulk of future demand. Addressing this imbalance requires mobilising more capital from diverse sources into EMDE energy systems.China continues to play a central role in global energy investment flows because of its large domestic investments and its large external capital spending on energy. Since…

Energy Policy Review Government action plays a pivotal role in ensuring secure and sustainable energy transitions. Energy policy is critical not just for the energy sector but also for meeting environmental, economic and social goals. Governments need to respond to their country’s specific needs, adapt to regional contexts and help address global challenges. In this context, the International Energy Agency (IEA) conducts Energy Policy Reviews to support governments in developing more impactful energy and climate policies.This Energy Policy Review was prepared in partnership between the Government of Brazil and the IEA. It draws on the IEA’s extensive…

Global Methane Tracker 2026
Around the world, many countries have made reductions in methane emissions a policy priority as part of their efforts to limit near-term global warming, enhance energy security, and improve air quality. The energy sector – including oil, natural gas, coal and bioenergy – accounts for around 40% of methane emissions from human activity and has some of the best opportunities to cut these emissions. The annually updated Global Methane Tracker provides essential data on methane emissions across the energy sector and the opportunities to bring them down.The Tracker presents the IEA’s latest sector-wide emissions estimates – based on the…

Global Energy Review 2025
Global Energy Review 2025 This edition of the Global Energy Review is the first comprehensive depiction of the trends that took place in 2024 across the entire energy sector, covering data for all fuels and technologies, all regions and major countries, and energy-related carbon dioxide (CO2) emissions. The latest data show that the world’s appetite for energy rose at a faster-than-average pace in 2024, resulting in higher demand for all energy sources, including oil, natural gas, coal, renewables and nuclear power. This growth was led by the power sector, with demand for electricity rising almost twice…

Southeast Asia Indicators Handbook for Just and Inclusive Transitions
Energy demand in Southeast Asia is growing, driven by rapidly growing population and economies, industrialisation and urbanisation. Many countries in the region have set out their own national decarbonisation targets and clean energy transitions commitments.Clean energy transitions in the region present unique opportunities to deliver broad socio-economic benefits, beyond emissions reductions, such as the creation of new decent jobs, economic diversification, reduced energy poverty and improved air quality. Tracking these benefits can help ensure that all parts of society benefit from these changes.In 2024, G20 leaders endorsed ten voluntary G20 Principles for Just and Inclusive Energy Transitions…

Global Energy and Climate Model
Scenario analysis of future energy trends Global Energy and Climate Model Over the past four years, the IEA has worked to develop a new integrated modelling framework: the IEA’s Global Energy and Climate (GEC) Model. This model is now the principal tool used to generate detailed sector-by-sector and region-by-region long-term scenarios across IEA's publications, including the World Energy Outlook series and Energy Technology Perspectives series.In 2021, the IEA adopted for the first time a new hybrid modelling approach relying on the strengths of both models. The integrated framework of the IEA’s Global…

Energy Transition Review for Enhancing Co-operation
The Philippines’ power sector This report is part of ongoing IEA collaboration with Asia Zero Emission Community (AZEC) partners to better understand the particular challenges these partners face in their energy transition and to provide a platform for co-operation among the AZEC partners. The report seeks to build a shared understanding of the challenges and opportunities facing the Philippine power sector, and to identify practical pathways that can help to strengthen its energy security, improve affordability and enable the country to achieve its long-term clean energy goals.This review has been prepared in collaboration with the Department of Energy…
