Energy Efficiency 2025
Market Report Energy Efficiency 2025 is the IEA’s primary annual analysis on global energy efficiency developments, showing recent trends in energy intensity and demand, investment, employment and policy. The report provides sector-specific analysis on industry, buildings, appliances and transport and explores system-wide themes such as emissions reductions, energy security, affordability and competitiveness. This report is launched in parallel with an update to the IEA Energy Efficiency Progress Tracker, which can be accessed through the IEA website.

Household Energy Affordability: Data and Indicators
A methodological framework for national monitoring Effective policy requires robust monitoring of household energy affordability, yet no unified methodological approach currently exists. The upcoming IEA report Household Energy Affordability: Data and Indicators, to be published in July, addresses this gap. This executive summary presents its key elements, including a robust methodological framework structured around dimensions, indicators and data to support policy discussions and national monitoring efforts.

Scaling Up Transition Finance Sectoral insights
…only greenhouse gas (GHG) emissions but also, among others, high water use, land degradation and biodiversity loss. Transition finance can unlock high-impact projects that lower emissions and avoid or mitigate other impacts, guided by practical KPIs.Natural gas: Natural gas is set to remain a part of the global energy mix for many decades but the applicability of transition finance to gas varies by country and sector and over time. Priority should be placed on front-loading methane abatement, reducing emissions from liquefied natural gas (LNG) liquefaction providing infrastructure for low-emissions gases and helping, alongside other technology options…

Global Methane Tracker 2026 Recent insights from methane emissions studies
Advances in measurement and data processing Methane detection has improved markedly in recent years by making better use of existing satellite arrays and launching new devices, improving airborne instrumentation and calibration, and deploying tower, stationary and handheld detectors more widely. Overall, detection limits have been optimised, coverage has broadened and observation times have increased. Meanwhile, advances in data processing have enhanced both the speed and the quality of analysis.These advances yield better coverage and sharper insights into the sources and scale of methane emissions. They also confirm that effective methane management requires multi-scale measurement frameworks that combine space…

How governments can best support consumers during this energy crisis
How governments can best support consumers during this energy crisis The conflict in the Middle East has triggered a major shock to global energy markets, with the effective closure of the Strait of Hormuz triggering the largest supply disruption in the history of oil markets and significantly impacting supplies of natural gas and a range of energy-related commodities.As concerns over supply security have grown, prices have risen across several parts of the energy system, increasing pressure on household budgets, public finances and economic activity more broadly. In response, many governments have announced emergency measures to protect consumers from…

Global Energy and Climate Model Techno-economic inputs
The Global Energy and Climate Model (GEC Model) uses macro drivers, techno-economic inputs and policies as input data to design and calculate the scenarios. The values for the different data categories and scenarios used in the GEC Model 2025 can be downloaded here.In particular more details regarding power generation technology costs for the Current Policies Scenario, the Stated Policies Scenario and the Net Zero Emissions by 2050 Scenario can be downloaded in excel format, including detailed projections at the 2050 horizon regarding overnight capital costs, annual O&M costs, efficiencies and other contributors to electricity costs at regional…

Financing the Modernisation of Power Systems Beyond Coal Executive summary
The role of coal in power systems is evolving This report assesses the potential applications, limitations and relevance of transition credits in Southeast Asia. Coal is the largest source of power generation worldwide and the largest source of energy-related carbon dioxide emissions. All Southeast Asian countries with coal in their power generation mix have adopted commitments to reduce coal-fired generation or emissions targets that imply a significant decline in coal consumption in the coming decades. To meet these targets, the International Energy Agency (IEA) has long emphasised that a range of strategies can be deployed to reduce coal…

The Implications of Oil and Gas Field Decline Rates
…and, by extension, for market balances.The International Energy Agency (IEA) has long examined this issue, and a detailed understanding of decline rates is at the heart of IEA modelling and analysis, underpinning the insights provided by the scenarios in the World Energy Outlook.This new report – based on analysis of the production records of around 15 000 oil and gas fields around the world – explores the implications of accelerating decline rates, growing reliance on unconventional resources, and evolving project development patterns for the global oil and gas supply landscape, for energy security and for investment. It also provides regional insights.
