The Implications of Oil and Gas Field Decline Rates Executive summary
Discussions on the future of oil and gas often overemphasise demand drivers and underappreciate supply drivers Debate over the future of oil and natural gas tends to focus on the outlook for demand, with much less consideration given to how the supply picture could develop. This asymmetry is misplaced and a thorough understanding of the rate at which production from existing oil and gas fields declines over time is more important than ever. The International Energy Agency (IEA) has long examined this issue. Decline rates – the annual rate at which production declines from an existing oil or gas field – underpin…

Global Hydrogen Review 2026 Cost acceptability
Analysis of the costs of hydrogen in different end-uses enables identification of the maximum acceptable costs for hydrogen users, i.e. the maximum amount that can be spent on the hydrogen feedstock within a low-emissions pathway while maintaining the same total levelised cost of production as the incumbent pathway to produce the same commodity.This can enable policy makers and investors to identify sectors with both high maximum acceptable hydrogen costs and high potential volumes that can serve as lead markets for low-emissions hydrogen. Cost acceptability can be influenced by policies and depends on technologies, fuels and…

World Energy Outlook 2022 An updated roadmap to Net Zero Emissions by 2050
Introduction In 2021, the IEA published its Net Zero by 2050: A Roadmap for the Global Energy Sector, which sets out a narrow but achievable pathway for the global energy sector to reach net zero emissions by 2050. However, much has changed in the short time since that report was published.The global economy rebounded at record speed in 2021 from the COVID-19 pandemic, with GDP growth reaching 5.9%. As energy intensity improvements stalled, global energy demand increased by 5.4%. Surging energy demand was in part met by increased use of coal, resulting in a 1.9 gigatonnes…

Multiple Benefits of Energy Efficiency for Business Turning the opportunity into reality
Across sectors, the evidence consistently shows that the value of energy efficiency extends far beyond energy savings, often matching or even exceeding them.A key challenge is that much of this value is not systematically captured in investment decisions. Business cases are often built on energy savings alone, overlooking gains in productivity, resource efficiency, product quality, brand reputation and workforce health. Reflecting these wider benefits can significantly strengthen investment cases and improve how efficiency projects compete for capital.This report draws on available evidence to highlight these broader benefits and why they matter in practice. The steps below show how…

World Energy Investment 2025 Source, flows and destination of global energy-related investment spending
Most energy investment is supported by commercial finance and made by private sponsors, but the sources of finance vary widely by technology and region. Today, 75% of the available finance for investment in the energy sector is commercial finance, but domestic and international public finance play important roles that vary widely across regions and sectors.

Pledges to Progress 2025 Pledges to Progress Company Assessment
The assessment shown below sets out actions reported by 116 oil and gas companies to achieve the goals set out in the Oil and Gas Decarbonisation Charter, agreed at COP28. It is a baseline assessment, in that the evaluations for each metric are based on public company reporting published in 2024, which often rely on data and progress from 2023, i.e. before the OGDC was launched.This is not an assessment of environmental performance. It tracks 25 specific aspects of target-setting, implementation strategies and disclosure, based on a framework put together by the International Energy Agency (IEA), the…
