Global Energy and Climate Model About the Global Energy and Climate Model
…emissions.Prices, which are both inputs and outputs of the model, include: fuel, end-user and CO2 prices. Developments in the 2025 modelling cycle The key sectoral and topic-specific model developments undertaken in 2025 include the following:The policies used to inform the GEC Model are now fully available online in the Policies and Measures Database and analysed in the Global Energy Policies Hub.Across all end-use sectors (buildings, industry, transport) energy-related investments assessments have been enhanced by incorporating new input data and a refined methodology for energy efficiency investments. All the investments for end-use sectors…

Germany 2025 Executive summary
…While this has supported a surge in renewables-based electricity generation, which will need to both continue and grow, more work lies ahead to decarbonise end-use sectors, such as transport, industry and buildings. Existing strategies and supportive policy measures in these sectors will need to be matched by a strong focus on effective, cost-efficient implementation. Given that German consumers pay among the highest electricity prices in Europe, policy developments will need to also be seen through an affordability and competitiveness lens, including by ensuring that the distributional impacts are well understood and that proactive measures are taken to…

Critical Mineral Traceability for Energy and Economic Security
Amid rising risks linked to the high concentration of critical mineral supply chains, the ability to track where minerals originate, how they move through supply chains, who has custody of them and how they are transformed is increasingly important for policymakers seeking to create diversified and responsible supply chains.This report provides insights from a first-of-its kind survey on traceability conducted by the IEA and OECD. More than 80 respondent companies active across supply chains of the six focus minerals (copper, lithium, nickel, cobalt, graphite and rare earth elements) provided results between October and December 2025. Drawing on…

Demand- and Supply-Side Measures for the Industry Transition
Policy brief As governments look to scale up lead markets for near-zero and low-emissions steel and cement, targeted policy measures can help overcome commercialisation barriers, capture emerging market opportunities and support broader government objectives. This policy brief explores a variety of possible policy instruments to stimulate demand and supply of such industrial materials, providing options that governments could adopt and adapt as part of their industrial policy framework – tailored to their unique circumstances to enhance effectiveness – along with practical next steps towards implementation.

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…

Rare Earth Elements
Pathways to secure and diversified supply chains The critical role of rare earth elements in strategic applications, ranging from energy technologies and advanced electronics to aerospace and defence systems, combined with their highly concentrated supply chains, has elevated their importance in both energy and broader economic security discussions in recent years. This report assesses the current state of the rare earth elements market, examining demand and supply dynamics and key technological developments. It analyses the full value chain from mining to permanent magnet production, evaluates vulnerabilities across supply chains, and highlights the implications of potential supply disruptions. Based on these…

Grid investments
…measures can also reduce grid congestion, a key factor in determining costs to manage the system. These congestion management costs tripled in Germany, the United Kingdom and the United States from 2019 to 2022, and can constrain industrial expansion. Implementing energy efficiency and demand response measures can decrease and shift peak demand to less congested periods when electricity prices are lower and there is less stress on grid infrastructure. Demand response has seen rising uptake around the world, but further electrification and demand decarbonisation are expected to significantly increase its importance. For instance, in Australia, where various mechanisms have been…

Sheltering From Oil Shocks
…supply disruption in the history of the global oil market, due to the near halt in shipping traffic through the Strait of Hormuz. The loss of supply is having significant impacts in global markets, pushing up prices for crude oil above $100/barrel, and leading to much higher prices for some refined products – notably diesel, jet fuel and liquefied petroleum gas (LPG). Concerns are growing about the impacts of higher prices on households, businesses and the broader economy.In this report, the IEA details 10 demand-side options open to households, businesses and governments to shelter themselves from today’s…

Global Energy Review 2026
Global Energy Review 2026 This edition of the Global Energy Review provides the first full assessment of trends across the entire energy sector in 2025, with data for all fuels and technologies, all regions and major countries, and energy-related carbon dioxide (CO2) emissions.The report covers estimates of energy demand by region and by source and fuel in 2025; developments in electricity demand and supply; deployment of selected energy technologies; and estimates of energy-related CO2 emissions. The report also assesses trends in energy intensity and analyses the impact of factors, such as weather effects, on energy demand and…

Southeast Asia Energy Outlook 2026 Energy outlook to 2050 based on today’s policy settings
…the STEPS. Industry remains the largest end-use sector, supported by expanding manufacturing and energy-intensive production. To 2035, Southeast Asia is one of the world’s fastest growing regions for aluminium iron and steel production, with output rising by 70%. This reinforces demand for electricity, coal and natural gas, while the young age of industrial assets limits near-term opportunities for fuel switching. In transport, electric vehicles and biofuels curb oil demand growth, avoiding around 1 mb/d of oil demand by 2035 together, reducing exposure to import price volatility and saving roughly USD 25 billion in oil imports, but…
