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…

Health
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores health. Why is energy efficiency important for health? Energy efficiency can improve health by creating healthy indoor and outdoor living environments with comfortable temperatures and humidity levels, and improved air quality. Key facts Energy efficiency measures have been linked to improved health, such as fewer respiratory illnesses.Targeted energy efficiency programmes can reduce doctor and hospital visits and save health costs. In New Zealand, a retrofit programme led to a 43% reduction in hospital admissions for respiratory conditions, while a similar programme in Ireland reduced the…

Oil Market Report - November 2025
The IEA Oil Market Report (OMR) is one of the world's most authoritative and timely sources of data, forecasts and analysis on the global oil market – including detailed statistics and commentary on oil supply, demand, inventories, prices and refining activity, as well as oil trade for IEA and selected non-IEA countries. Highlights World oil demand growth rebounded to 920 kb/d in 3Q25, mainly due to stronger deliveries in China. The third-quarter increase was more than double 2Q25’s 430 kb/d y-o-y expansion, as the macroeconomic picture broadly improved on easing trade tensions. Worldwide…

Energy Efficiency in China’s Buildings Sector
Policy opportunities Over the past two decades, China has made significant strides in energy efficiency, with strong reductions in primary energy intensity across the economy and increased energy services. Much of China’s improvement has come from energy efficiency upgrades in industry and overall economic structural shifts. The buildings sector accounts for approximately 20% of its total final energy consumption and its intensity has decreased at a slower rate. There remains significant potential to unlock further energy savings through technical and policy initiatives in buildings.This report outlines opportunities for actions, targets and timelines that could improve energy efficiency in…

Emission reductions
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores emission reductions. Why is energy efficiency important for emission reductions? Energy efficiency can reduce emissions of greenhouse gases and air pollutants and make the energy system more sustainable. Key facts Since 2010, efficiency measures avoided energy-related carbon dioxide (CO₂) emissions equivalent to nearly 20% of the global total in 2023. This is more than the entire energy-related emissions of India and the European Union combined. Accelerating efficiency improvements could deliver a third of all energy-related CO₂ emission reductions between now and 2030 in…

The Implications of Oil and Gas Field Decline Rates
Much attention today focuses on uncertainties affecting the future evolution of oil and natural gas demand, with less consideration given to how the supply picture could develop. However, understanding decline rates – the annual rate at which production declines from existing oil and gas fields – is crucial for assessing the outlook for oil and gas supply and, by extension, for market balances.The International Energy Agency (IEA) has long examined this issue, and a detailed understanding of decline rates is at the heart of IEA modelling and analysis, underpinning the insights provided by the scenarios in the World Energy Outlook.This new…

Renewables in District Energy
This report examines how renewables can play a larger role in district energy systems, helping to deliver cleaner, more secure and more efficient heating and cooling. District energy networks already supply heat to around 600 million people worldwide, but many systems remain heavily dependent on fossil fuels, exposing consumers and utilities to price volatility, supply risks and high emissions.The report provides a global overview of district energy systems, their fuel mixes, market conditions, governance models and affordability implications. It explores the growing opportunities offered by renewable and recovered heat sources, including bioenergy, geothermal, solar thermal, waste heat, large-scale heat…

Competitiveness
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores competitiveness. Why is energy efficiency important for competitiveness? Increasing energy efficiency can improve competitiveness at both the firm level – by reducing costs, improving operations and increasing product value – and at the country level, by reducing the amount of energy required to produce economic output. Key facts Today the world’s industries produce nearly 20% more value added with a given amount of energy, compared with two decades ago. In the industrial sector, energy management can lead to more than 10% in annual energy cost savings within…

The IEA Oil Market Report (OMR) is one of the world's most authoritative and timely sources of data, forecasts and analysis on the global oil market – including detailed statistics and commentary on oil supply, demand, inventories, prices and refining activity, as well as oil trade for IEA and selected non-IEA countries. Highlights Global oil demand is forecast to rise by 850 kb/d in 2026, up from 770 kb/d last year. As in 2025, non‑OECD economies will account for the entire increase, with China taking the lead on a country level. Petrochemical feedstock products will represent more…

Gas 2025
Analysis and forecasts to 2030 Global gas markets are set to undergo major changes by the end of the decade, with the coming wave of liquefied natural gas (LNG) production capacity set to profoundly transform market dynamics. The unprecedented scaling up of LNG supply is expected to improve gas supply security and make natural gas more affordable – including in emerging, price-sensitive import markets. However, to account for these shifts, LNG producers and suppliers may need to adapt their medium-term strategies.The Gas 2025 medium-term report from the International Energy Agency (IEA) examines this coming transformation and its…
