Gas Market Report, Q2-2026
This edition of the IEA's quarterly Gas Market Report provides a comprehensive review of developments during the 2025/26 heating season and a special spotlight on the effects of the war in the Middle East on international gas markets. Amid the major supply shock caused by the disruptions to shipping through the Strait of Hormuz and attacks on regional energy infrastructure, it examines the conflict’s implications for gas supply and demand at both the regional and global levels. The report also analyses the consequences for storage, shipping and prices – providing critical insights on evolving market trends.The loss of nearly…

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…

…energy retrofits led to a 81% reduction in self-reported illness among households. Meanwhile, the evaluation of the Warm Up New Zealand Programme concluded that 90% of all benefits are health-related, with hospital admissions for respiratory conditions dropping by 43%, saving the country over USD 1 billion in health costs. In Ireland, in an analysis of the Warmth and Wellbeing Scheme, participants report that the improved efficiency of their homes reduced the number of doctor visits by 50% and lowered hospital admissions by 40%.In addition to physical health, energy efficiency can also lead to improvements to mental health…

…transport and industry; support targeted measures where progress is lagging; and build shared ownership of the transition.A well-defined roadmap would provide the predictability required for investment, help avoid bottlenecks in supply chains and workforce skills, and ensure that Portugal’s 2030 and 2045 goals remain achievable. This effort could build on the ongoing revision of the Roadmap for Carbon Neutrality 2050, led by the Portuguese Climate Agency, which offers an opportunity to integrate sectoral pathways under a coherent national framework.2. Ensure a fair and effective energy transition by empowering the groups most impacted by, and critical to…

…tax credits for new projects starting in 2026. In contrast, the United Kingdom allocated an all-time high allocation to the Low Carbon Contracts Company, managing the contract-for-difference in the country, with USD 56 billion in 2025 alone.Since 2015, government spending in the buildings sector has grown sixfold to reach USD 56 billion in 2025, largely directed towards energy efficiency retrofits and space heating electrification. Key programmes include Italy’s Superbonus (USD 24 billion since 2021), the United States’ tax credits for residential energy efficiency property (USD 39 billion since 2015), Germany’s building efficiency and renewable energy programme (USD 56 billion since 2021) and…

Businesses see competitive value of energy efficiency, but smaller firms struggle to access solutions
…position in global markets. Yet not all firms have the same capacity to quickly improve their energy efficiency.New analysis of the 2025 IEA Industrial Competitiveness Survey – which covered 1 000 companies across 14 countries – shows that business leaders view energy efficiency as closely linked to their competitive performance. But the survey also highlights a persistent divide: while large companies are often well positioned to capture these benefits, many that are small and medium-sized face barriers that limit their ability to invest in efficiency and compete on the same terms. Energy efficiency drives competitiveness across all sectors, with select industries…

Energy Efficiency Policy Toolkit Transport
Introduction Private cars and vans were responsible for more than 25% of global oil use and around 10% of energy-related CO2-emissions in 2023. Doubling global annual energy intensity improvement by 2030 would require the efficiency of cars to improve by 5% each year. An integrated policy approach combining regulation, information and incentives is the most effective way to achieve this goal.Regulations such as fuel economy standards and heavy-duty vehicle standards encourage manufacturers to introduce more efficient vehicles, thereby significantly reducing greenhouse gas emissions. Countries with regulations and/or efficiency-based purchase incentives in place improve efficiency…

Global Energy and Climate Model Accelerating Clean Cooking and Electricity Services Scenario (ACCESS)
…billions of people in around 100 countries remain without access to basic modern energy services. Today nearly 2 billion people lack access to clean cooking and 730 million people lack access to electricity. Millions of households, businesses and public institutions such as clinics and schools operate without reliable modern energy. This limits productivity and hinders socioeconomic development. It also perpetuates the use of traditional biomass, with damaging consequences for health and the environment.The Accelerating Clean Cooking and Electricity Services Scenario (ACCESS) charts a path to achieve universal access to clean cooking and electricity based on the best rates of progress achieved historically…

…and lead to lower vacancy rates and longer equipment lifespans. Key facts Energy efficient buildings can command a premium on sale and rental price in both the residential and commercial sectors. Studies show that sale price premiums for energy efficient buildings range from 3% to 15% in residential buildings and 13 to 20% in commercial buildings. Key analysis Studies show that individuals and businesses are willing to pay a higher rent and/or sales price for property with improved energy performance, such as that expressed in energy performance certificates. Evidence from the United States and Germany suggests that sales price…
