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 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…

Unlocking Ukraine’s Hydrogen Opportunity: A Roadmap
Ukraine’s energy sector has been severely affected by the Russian Federation’s full-scale invasion. The power sector went from having a large capacity surplus before the war to a power deficit in 2024 due to Russia’s attacks. This has focused attention on energy security and restoring the reliability of supply. Hydrogen demand from conventional applications in refining and ammonia has also plunged, falling 80%, with most of these assets in southern Ukraine, where the frontline and occupied areas are located. Overall economic damage from the war has been extensive, with reconstruction costs previously estimated by the World…

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…

Integrating Variable Renewable Energy in Kenya
Key challenges and strategic priorities Building on its renewable energy success, Kenya is now focused on managing a secure and reliable electricity system. With nearly 90% of the generation mix derived from renewable sources and electricity access rising from 37% in 2013 to 79% in 2025, the country has established itself as a regional leader in energy development.Integrating Variable Renewable Energy in Kenya explores how Kenya can strengthen its power system amid rising shares of variable renewable energy (VRE). The report identifies Kenya’s system to be operating in Phase 3 of the IEA’s VRE integration framework, where…

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…

IEA Guide to Reporting Energy Technology RD&D Budgets
This manual, developed by the International Energy Agency (IEA), provides comprehensive guidance for national experts responsible for reporting energy technology research, development, and demonstration (RD&D) budgets. It outlines the methodology and classification system used to collect and structure RD&D data across IEA member countries, ensuring consistency and comparability. The manual is divided into two main sections: fundamentals of RD&D budget reporting and a detailed classification of energy technologies. It defines RD&D in alignment with the OECD Frascati Manual and clarifies the scope of public and private sector reporting. It also provides instructions for completing the IEA…

Ramping up Heat Pumps in Moldova: A Roadmap
Buildings account for more than half of Moldova’s final energy consumption, with three-quarters of that used for space and water heating. At the same time, Moldova lacks domestic hydrocarbon resources and imports more than 80% of its primary energy. Heat pump technology offers Moldova an effective means of accelerating the transition in building heating.The recent expansion of Moldova’s solar and wind capacity also means that heat pumps can now play a greater role in cutting greenhouse gas emissions and lowering local air pollution. Finally, Moldovan’s 2024 referendum, endorsing the goal of European Union membership, underscores…

Ukraine’s Energy Security
A pre-winter assessment As Ukraine enters its fourth winter of war, ensuring that residents retain reliable access to heat and power is of the utmost importance. While Ukraine made strong strides in rebuilding and strengthening the resilience of its energy system this past spring and summer, the situation remains fragile, and the risk of huge disruptions and widespread destabilisation remains – particularly as Russia expands the scope and sophistication of its attacks.This analysis builds on the IEA’s September 2024 report, Ukraine’s Energy Security and the Coming Winter. It provides an update on the latest developments through October…
