The Value of Demand Flexibility
Benefits beyond balancing This policy brief, developed under the International Energy Agency’s Digital Demand-Driven Electricity Networks (3DEN) Initiative, examines the value of demand flexibility as a core component of modern electricity systems, with a strong emphasis on its role in improving energy efficiency. As electricity demand grows and power systems become more electrified, decentralised and renewable-rich, managing when and how electricity is used is increasingly as important as expanding supply.The brief sets out a clear framework for understanding demand flexibility and highlights its contribution to an efficiency-first approach to power system planning and operation. By…

Clean Energy Transitions Programme 2024
Annual report 2024 The Clean Energy Transitions Programme (CETP) is the International Energy Agency’s flagship initiative for accelerating clean energy transitions worldwide. Since its inception in 2017, the CETP has played a vital role in tackling the diverse challenges of energy transitions across the globe, fostering partnerships and providing tailored, actionable solutions. The programme is structured around three key pillars: directly supporting national transitions; strengthening multilateral co‑ordination; and delivering global analysis to inform policy dialogue.With significant milestones achieved in 2024, the CETP has supported over 320 high‑level meetings with policy makers, conducted 735 workshops and technical exchanges with…

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…

Financing CCUS at Scale
How to Mobilise Private Capital Carbon capture, utilisation and storage (CCUS) is an important area of attention for governments and financiers as both look to balance policy and investment goals. Recent financial investment decisions of major projects show promise in a sector that is gaining momentum, but its future success depends on viable business models and effective risk allocation across the value chain.In this context, Financing CCUS at Scale is the IEA’s latest report on what it takes to move CCUS projects from the drawing board to operation. Building on expert interviews with leading financial institutions, the report…

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…
