Global Energy Review 2025 CO2 Emissions
Energy sector carbon emissions reached a new record in 2024 Total energy-related CO2 emissions increased by 0.8% in 2024, hitting an all-time high of 37.8 Gt CO2. This rise contributed to record atmospheric CO2 concentrations of 422.5 ppm in 2024, around 3 ppm higher than 2023 and 50% higher than pre-industrial levels. In 2024, CO2 emissions from fuel combustion grew by around 1% or 357 Mt CO2, while emissions from industrial processes declined by 2.3% or 62 Mt CO2. Emissions growth was lower than global GDP growth (+3.2%), restoring the decades-long trend of decoupling emissions…

Outlook for Biogas and Biomethane Biogas and biomethane outlook to 2050
The landscape for biogases is very different now compared to our last Outlook in 2020, with total demand 32% higher in 2040 in the STEPS than in the New Policies Scenario at the time. Whereas natural gas prices in 2020 were at record lows, the Russian invasion of Ukraine in 2022 triggered interest in developing biomethane to substitute imported natural gas. The revised figure is driven in part by strengthened policy incentives, notably in Europe and China. There is a strong continued use case for biogases in the Outlook scenarios. Electricity's share in total final consumption increases from 20…

Competitiveness
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores competitiveness. Why is energy efficiency important for competitiveness? Increasing energy efficiency can improve competitiveness at both the firm level – by reducing costs, improving operations and increasing product value – and at the country level, by reducing the amount of energy required to produce economic output. Key facts Today the world’s industries produce nearly 20% more value added with a given amount of energy, compared with two decades ago. In the industrial sector, energy management can lead to more than 10% in annual energy cost savings within…

Energy Technology Perspectives 2026 Executive summary
Despite headwinds, the markets for clean energy technologies and fuels are expanding rapidly Deployment of many clean energy technologies, fuels and materials has been growing fast, but shifting policies, economic conditions and technological progress are creating uncertainty about their prospects and economic potential. Against this backdrop, the IEA’s flagship technology publication Energy Technology Perspectives (ETP) aims to separate the signal from the noise, by providing timely data, scenarios and analysis across deployment, manufacturing, trade, competitiveness and security. At a time when misjudging the moment risks wasting capital or stalling momentum, this report has been designed to help decision makers…

Global Methane Tracker 2026 Key findings
No sign that global energy-related methane emissions fell in 2025 despite progress in some areas The fossil fuel sector accounts for around 35% of methane emissions from human activity, yet there is still no sign that methane emissions from fossil fuel operations are falling, despite well-known and proven mitigation pathways. Oil, gas and coal production output reached record highs in 2025, and the International Energy Agency (IEA) estimates that methane emissions from these activities total 124 million tonnes (Mt) a year: oil is the largest source at 45 Mt, followed by coal at 43 Mt, and natural gas at 36 Mt. A…
