More stringent and broader coverage of fuel efficiency standards for light-duty vehicles is needed
For cars and vans, increasing fuel efficiency standards is important as even in the Net Zero Emissions by 2050 Scenario, nearly 80% of cars and vans on the road in 2030 are still powered with internal combustion engines. Sales of heavier, less efficient SUVs reached around 46% of global sales in 2022, while electric vehicles were just 14% of sales. More and more countries are formulating vehicle efficiency standards and some are even putting in place zero-emission vehicle sales requirements. To be in line…

COP28 Tripling Renewable Capacity Pledge 2025: Update
…reflected government ambition toward the tripling pledge.This report is an update to the 2024 analysis with extended geographical coverage. It reviews all new NDCs submitted until the end of COP30 and quantifies renewable ambitions for 2030. It also examines updated national policies and plans for almost 200 countries from June 2024 to December 2025 to identify how national renewable capacity ambitions have changed since the last report. This analysis benchmarks renewable ambitions in new NDC submissions against national plans. The report also assesses how they both align with the tripling global renewable capacity by 2030 pledge.Renewable Energy Progress…

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 security
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores energy security. Why is energy efficiency important for energy security? Energy efficiency can help mitigate energy security risks by reducing the reliance on fossil fuel imports, improving grid reliability, and acting as a buffer to supply shocks. Key facts Efficiency gains from the last two decades avoided the need for 20% more fossil fuel imports in IEA countries. Energy efficiency and demand response can support grid reliability by reducing peak demand. For instance, more efficient air conditioners in India could lower the impact of heatwaves on…

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…

World Energy Employment 2025
The World Energy Employment (WEE) report series provides comprehensive tracking and analysis of the global energy workforce, including estimates of its size and distribution across regions, sectors, and technologies. It also assesses how energy labour requirements evolve to 2035 across all IEA scenarios.The WEE 2025 – the fourth edition – examines how skilled labour needs and shortages have changed since the series first highlighted these issues in 2022, and explores their implications for education and training systems, wages, policy, and the global buildout of energy infrastructure. This year’s report introduces, for the first time, detailed occupation-level estimates that offer…

Energy Efficiency Policy Toolkit
To accelerate action on energy efficiency, the IEA created the Policy Packages for Energy Efficiency in 2022 to support governments in designing and implementing effective energy efficiency measures by combining policies across three core pillars: regulation, information, and incentives.The IEA then developed an Energy Efficiency Policy Toolkit that integrates the Policy Package for Energy Efficiency, with concrete examples for each end-use sector. The Toolkit shares strategic principles to guide policy makers to enhance and expand their energy efficiency policies and programmes.Building on this foundation, the Energy Efficiency Policy Toolkit, updated on the occasion of the 10th Annual Global Conference on Energy Efficiency in…
