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.

Global Energy and Climate Model
Scenario analysis of future energy trends Global Energy and Climate Model Over the past four years, the IEA has worked to develop a new integrated modelling framework: the IEA’s Global Energy and Climate (GEC) Model. This model is now the principal tool used to generate detailed sector-by-sector and region-by-region long-term scenarios across IEA's publications, including the World Energy Outlook series and Energy Technology Perspectives series.In 2021, the IEA adopted for the first time a new hybrid modelling approach relying on the strengths of both models. The integrated framework of the IEA’s Global…

Pledges to Progress 2025
An assessment of transparency of the oil and gas industry’s emissions reduction efforts At COP28, more than 50 of the world’s leading oil and gas companies launched the Oil and Gas Decarbonization Charter (OGDC), laying out a series of ambitions to achieve net zero operational emissions by 2050. As global methane and flaring emissions continue to rise, these ambitions are more important than ever to reduce energy waste and mitigate the harmful consequences of climate change.To support accountability and transparency, the International Energy Agency (IEA), the United Nations Environment Programme (UNEP) International Methane Emissions Observatory (IMEO) and…

Policy Toolbox for Industrial Decarbonisation
The Policy Toolbox for Industrial Decarbonisation is a repository of policy instruments available to assist governments as they design, develop and implement their strategies for industrial decarbonisation. This work, undertaken as part of the Climate Club's Work Programme, builds on the policy toolbox outlined in IEA’s 2022 Achieving Net Zero Heavy Industry Sectors in G7 Members report, with the addition of further details on the instruments and considerations for implementation.A robust industrial decarbonisation policy strategy is likely to include multiple different instruments, as governments choose the instruments that are most suited to their individual circumstances and objectives…

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…

Advancing Methane Emissions Reductions by National Oil Companies
National oil companies (NOCs) are responsible for around half of all global oil and gas production today and their actions strongly influence methane abatement prospects. More than 30 NOCs have joined the Oil and Gas Decarbonization Charter (OGDC) and are engaging in initiatives to tackle methane emissions and flaring. There is a major opportunity for NOCs looking to implement best practices in methane management to learn from the experience of peers in order to deploy strategies that are adapted and tailored to their circumstances. Best practices include adopting measures to limit flaring and venting, implementing leak detection and repair programmes…

Cost of Capital Observatory
Tracking the cost of capital for clean energy projects in emerging and developing economies The Cost of Capital Observatory is an initiative from the IEA, the World Economic Forum, ETH Zurich and Imperial College London. The aim of the Observatory is to increase transparency in the energy sector and inspire investor confidence, especially in emerging and developing countries where data on financing costs is scarcer.The Observatory is divided into three sections:A Dashboard that provides free data on the cost of capital for energy projects in emerging and developing economies, updated with 2023 and 2024 data in July and…

Prospects for Natural Gas Certification
This report offers an overview of the role of certification in natural gas supply chains, provides a broad mapping of existing initiatives, highlights selected regulatory and market developments, identifies areas where improvements may be needed, and presents recommendations to support the development of credible certification frameworks.Certified natural gas refers to gas whose environmental and social attributes – such as greenhouse gas (GHG) emissions performance, water use, local community impacts and worker safety – have been independently verified against defined criteria or benchmarks. In 2024, around 7.5% of global natural gas production was certified, with volumes primarily originating from North America…

Economic growth
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores economic growth. Why is energy efficiency important for economic growth? Energy efficiency allows countries to generate more economic activity using the same amount of energy. It is also linked to increased labour productivity and other economic benefits. Key facts Compared with 2000, today’s global economy produces 36% more GDP per unit of energy. Energy efficiency progress over the last 20 years means that close to an extra USD 50 trillion can today be produced using the same amount of energy. This energy efficiency bonus is equivalent to…

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…
