Energy security
…Key analysis Energy efficiency policies in different sectors have been effective in reducing fossil fuel imports. In the European Union, the strongest reduction was in gas imports, driven by strong energy efficiency improvements in the industrial sector. Meanwhile, in Japan the strongest reductions were in oil imports, due to some of the most stringent fuel economy standards both for passenger and commercial vehicles. A closer look at electricity security Energy efficiency and demand response policies can also contribute to electricity security by reducing the risk of outages resulting from peak demand.Different programmes have demonstrated success in reducing peak electricity…

Emission reductions
…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 a pathway aligned with reaching net zero emissions by 2050 – the largest share of any sector or technology. Energy efficiency also improves air quality and people’s health by lowering local air pollutants such as fine particulate matter (PM2.5) and nitrous oxide. Key analysis Global energy-related CO2 emissions increased by around 15% between 2010 and 2023, driven by an…

Energy savings
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores energy savings. Why is energy efficiency important for energy savings? Energy efficiency measures reduce the amount of energy required to fuel and grow our economies. In economies where energy demand is set to grow significantly, efficiency also helps improve people’s lives by increasing access to additional energy services. Key facts In the last two decades, efficiency measures have generated over 27 EJ of energy savings in IEA countries alone, equivalent to 20% of total energy demand.The industry (including manufacturing) and services (including commercial buildings) sectors…

Delivering Sustainable Fuels
…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. Progress must occur on multiple fronts to increase uptake and foster a large and diverse set of sustainable fuel pathways…

Northwest European Hydrogen Monitor 2025
…Northwest Europe could gradually scale up in the short- to medium-term. Northwest European countries now have ambition to develop up to 30 to 35 gigawatts (GW) of electrolyser capacity by 2030. However, most low-emissions hydrogen projects are currently in the early stages of development. Their success will depend largely on supportive policies and regulatory frameworks. The cost-efficient development of low-emissions hydrogen markets also necessitates a regional approach that maximises existing synergies among national markets. This is the third edition of the Northwest European Hydrogen Monitor. It provides an annual update of low-emissions hydrogen market developments in…

Economic growth
…2030. Increase in labour productivityAn analysis of over 15 000 European firms found that those investing in energy efficiency can see increases in labour productivity – the amount of economic activity per unit of labour – between 1.4% and 3.6% compared with firms with no investment in energy efficiency.Improvement of public budgetsWhether by reducing government expenditures on energy or by generating increased tax revenues through greater economic activity and/or increased spending on energy efficiency-related goods and services, energy efficiency improvements can have important impacts on the budgetary position of national and sub-national entities. In the European Union…

Sustainable Transport for Georgia: A Roadmap
The International Energy Agency (IEA) developed this Sustainable Transport Policy for Georgia roadmap under the European Union-funded five-year EU4Energy programme, which supports evidence-based energy policy and data capabilities in Eastern Partnership countries, including Georgia.The roadmap supports sustainable transport planning at national and city levels, summarising legislation, planning documents, and research on passenger and freight transport. Key metrics include accessibility, safety, convenience, equity, energy efficiency, emissions reduction, congestion and service reliability. Policies and targets are proposed to help Georgia meet the United Nations’ Sustainable Development Goals and achieve its Nationally Determined Contribution (NDC) pledges.The government of…

What Next for the Global Car Industry
An Energy Technology Perspectives Special Report The global car industry has operated under relatively stable conditions for decades. The world’s largest car manufacturers are based in the European Union, Korea, Japan and the United States, and – more recently – in China, and the car industry is a major contributor to the economy in these countries. The strength of many of these car makers is built on decades at the forefront of technological innovation around the internal combustion engine (ICE), as well as highly integrated and optimised supply chains that allow for vehicles and their components to be produced at low…

Gaining an Edge
The Role of Energy Efficiency in Enhancing Competitiveness Energy efficiency delivers more than energy savings and emission reductions – it can also improve the competitiveness of countries and firms. From increased profitability to job creation, energy efficiency helps firms compete amid high costs, growing demand, and rising trade pressures. In today’s global context, energy efficiency is not only a matter of energy policy, but also of economic policy.The report analyses historical progress in industrial energy efficiency and its role in enhancing industrial competitiveness. It includes comparisons of firm-level energy efficiency, identifying performance gaps and opportunities for further improvement. Drawing…
