Scaling Up Transition Finance Executive Summary
Successful transitions need finance that goes where the emissions are Actions by the world’s most emissions-intensive sectors, companies, and countries are crucial to placing the world on a sustainable pathway. Yet, investments that could deliver meaningful reductions in their environmental footprint often do not receive sufficient financial support. Currently, finance is drawn heavily to certain “green” assets and activities—most prominently renewable power. While vital, these investments alone cannot deliver all the changes needed to cut global emissions, especially in areas where clean technologies are not yet commercially available or cost competitive. This is where transition finance comes…

Global Energy Review 2025 Key findings
Global energy demand grew by 2.2% in 2024 – faster than the average rate over the past decade. Demand for all fuels and technologies expanded in 2024. The increase was led by the power sector as electricity demand surged by 4.3%, well above the 3.2% growth in global GDP, driven by record temperatures, electrification and digitalisation. Renewables accounted for the largest share of the growth in global energy supply (38%), followed by natural gas (28%), coal (15%), oil (11%) and nuclear (8%).Emerging and developing economies accounted for over 80% of global energy demand growth. In China, growth…

Renewables 2021 Biofuels
Forecast summary Global demand for biofuels is set to grow by 41 billion litres, or 28%, over 2021-2026 in the main case. The recovery to pre-Covid-19 demand levels accounts for one-fifth of this demand growth. Government policies are the principal driver of the remaining expansion, but other factors such as overall transport fuel demand, costs and specific policy design influence where growth occurs and which fuels grow quickest. The combination of these influences pushes Asian biofuel production past that of Europe during the forecast period. Policies in the United States and Europe help demand for renewable…

Renewables 2025 Renewable heat
Heat accounted for almost half of total final energy consumption and 37% of energy-related CO2 emissions in 2024 Annual heat consumption expanded by 6% globally over 2018-2024. Renewable energy, excluding traditional uses of biomass, met only half of this increase, with its share in global heat consumption rising to 14% in 2024. Nearly 80% of global growth in renewable heat use was in the form of bioenergy (especially in industry) and renewable electricity (mainly in buildings).Industry sector renewable heat use grew the most in China over the last six years, driven by the expansion of industries such…

Global Hydrogen Review 2025 Five key questions about hydrogen
Is the slow progress of projects derailing the hydrogen sector? Recent headlines reporting project delays, cancellations and downward revisions of ambitions for the adoption of low-emissions hydrogen, have led many to question whether the industry has hit another “hype cycle” like those in the 1970s, 1990s, and early 2000s. However, a deeper analysis reveals a different story. Despite falling short of the ambitious targets from the early 2020s, the sector is achieving remarkable milestones that demonstrate clear progress.The scale of electrolyser projects is growing fast. In 2021, the world's largest reached 30 MW. In 2025, a 500 MW project…

Energy Efficiency 2025 Executive summary
Global energy efficiency progress sees improvement in 2025, but remains off track to meet global goal Global energy efficiency progress is set to improve by 1.8% in 2025, up from around 1% in 2024. Preliminary estimates indicate that several key regions are showing some signs of stronger progress compared to their average since 2019. For example, energy intensity progress in 2025 is estimated to be over 3% in the People’s Republic of China (hereafter “China”) and over 4% in India, well above their averages in the years since 2019. In the United States and the European Union (EU…
