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…

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 Luxembourg and the IEA. It draws on the IEA’s extensive…

Economic growth
…almost two times the GDP of the United States without needing to increase energy consumption.Energy efficiency can generate broader economic benefits, with studies also showing improvements in labour productivity and public budgets. Key analysis Energy is a fundamental input into nearly every aspect of the economy. As the economy grows, so does the demand for energy. However, energy efficiency plays a crucial role by allowing us to achieve more with less, enabling a gradual decoupling of economic growth from energy consumption over time. A closer look at economic benefits Energy efficiency improvements can deliver benefits across the whole economy…

Heat Pump Taxonomy
A common framework for heat pumps classification and data Heat pumps are a cornerstone technology for achieving secure, affordable and sustainable heating. They have become one of the most common heating technologies and have the potential to impact significantly future trends for energy consumption in buildings and beyond.Tracking and analysing the pace of heat pump deployment compared to that of conventional heating technologies is essential for understanding future needs with regards to energy demand, investments in electricity infrastructure and fuel supply.Despite their growing importance, data on heat pump installations, as well as on their performance and cost, remain…

Oil Market Report - June 2026
… Highlights Global oil demand is forecast to decline by 1.1 mb/d y-o-y in 2026. This represents a downgrade of 700 kb/d compared with our May Report, as 2Q26 deliveries plunged by 5 mb/d y-o-y in the face of higher fuel prices and disruptions to product availability. We see growth rebounding to 2 mb/d in 2027, as a normalisation of trade flows, lower oil prices and an improving economic outlook contribute to the recovery.Global supply is set to fall by 3.9 mb/d to 102.4 mb/d in 2026…

Asset values
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores asset values. Why is energy efficiency important for asset values? Energy efficiency can increase the value of assets, such as homes, buildings or equipment, and lead to lower vacancy rates and longer equipment lifespans. Key facts Energy efficient buildings can command a premium on sale and rental price in both the residential and commercial sectors. Studies show that sale price premiums for energy efficient buildings range from 3% to 15% in residential buildings and 13 to 20% in commercial buildings. Key analysis Studies show that individuals…

Oil Market Report - May 2025
…Demand growth averages 740 kb/d in 2025 and 760 kb/d in 2026, despite accelerating OECD declines of -120 kb/d and -240 kb/d, respectively.World oil supply looks on track to rise by 1.6 mb/d to 104.6 mb/d on average in 2025, and by an additional 970 kb/d in 2026. Non-OPEC+ producers are set to add 1.3 mb/d this year and 820 kb/d next year, even as US LTO supply has been reduced. Based on the latest plans, OPEC+ will add 310 kb/d of extra supply this…

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…
