Delivering Sustainable Fuels
…hydrogen-based fuels – offer multiple benefits for the energy sector. They complement electrification and energy efficiency in energy transitions, and are particularly important for sectors that continue to be reliant on fuel-based solutions such as aviation, shipping, and parts of road transport and industry. Sustainable fuels can also enhance energy security, strengthen environmental sustainability and stimulate economic development, particularly in rural areas.If fully legislated and implemented, current and proposed national and international policies would put the use of sustainable liquid and gaseous fuels on a path to nearly double from 2024 levels by 2030 and quadruple by 2035…

Assessing emissions from LNG supply and abatement options
…and regasification. It also discusses the significant emissions reductions that are technically feasible with today’s technologies including through methane abatement, electrification using low-emissions power, process efficiency improvements, and the elimination of routine flaring, as well as carbon capture, utilisation and storage (CCUS) for managing the naturally-occurring CO2 from LNG supply. Introduction Around 550 billion cubic metres (bcm) of natural gas were exported as liquefied natural gas (LNG) in 2024, just under 15% of global natural gas consumption. A further 500 bcm of natural gas were transported through pipelines. Global LNG supply has grown faster than overall natural gas demand…

Multiple Benefits of Energy Efficiency
As energy efficiency continues to gain attention as a key resource for economic and social development across all economies, understanding its real value is increasingly important. The multiple benefits approach seeks to expand the perspective of energy efficiency beyond the traditional measure of energy savings by identifying and measuring its impacts in full bloom.

Energy Efficiency Policy Toolkit
…case studies, offering practical insights into the successful implementation of energy efficiency policies across diverse national and sectoral contexts.The Toolkit builds on earlier IEA work to advance energy efficiency policy. In 2022, the IEA introduced Policy Packages for Energy Efficiency to help governments deploy coordinated policy approaches across these three pillars. The Energy Efficiency Policy Toolkit was subsequently developed to also integrate concrete, sector-specific guidance, along with best practices from around the world.Ten strategic principlesBased on the IEA’s analysis of best practices and the work of the Global Commission for Urgent Action on Energy Efficiency, the following…

Designing Energy Efficiency Policies to Enhance Affordability
…designing energy efficiency policies that support affordability, particularly in the buildings sector.As part of this work, the IEA conducted a survey with G7 governments to better understand the obstacles they face. On the consumer side, major challenges include the landlord-tenant split incentive, high upfront costs and administrative complexity. On the supply side, governments identified skills shortages and difficulties in reaching underserved communities.The report analyses the affordability-focused energy efficiency policies of G7 countries. These include targeted financial support, simplified programme design, strong local delivery models, and better integration with workforce development. Embedding affordability into energy efficiency policy…

Energy Efficiency 2025
Market Report Energy Efficiency 2025 is the IEA’s primary annual analysis on global energy efficiency developments, showing recent trends in energy intensity and demand, investment, employment and policy. The report provides sector-specific analysis on industry, buildings, appliances and transport and explores system-wide themes such as emissions reductions, energy security, affordability and competitiveness. This report is launched in parallel with an update to the IEA Energy Efficiency Progress Tracker, which can be accessed through the IEA website.

Energy Efficiency in China’s Buildings Sector
…progress in achieving them. Regulation for new buildings in China, such as building codes, is relatively strong. However, as the rate of construction is slowing, policy priorities are shifting towards retrofitting existing buildings. Here, the IEA estimates that through strong policy action and best-in-class technology, China could reduce energy consumption by up to 65% in buildings constructed between 1995 and 2010, representing energy savings of over 8 000 Petajoules.The report includes examples from across China and the world on leading regulatory instruments, financial incentives, and information-based tools that can drive energy efficiency in the buildings sector.

Multiple Benefits of Energy Efficiency for Business
Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone. However, the value of energy efficiency extends beyond energy savings.This report builds on the IEA’s work on the multiple benefits of energy efficiency and focusses on how these gains materialise in businesses. Key benefits range from productivity and product quality improvements to brand image or health benefits for employees and…

Energy savings
…compensated for the increase in energy use due to increased activity, such as home building and increased home sizes. In the transport sector, most efficiency improvements were realised in passenger vehicles – around one-sixth of the total. These energy savings were higher than the increased demand due to the rising number, frequency and distance of people travelling. Efficiency improvements in freight transport, such as trucks, drove around 1% of the total energy savings. This was lower than the rise in freight transport activity over the same period.
