Hydrogen
Low-emissions hydrogen projects are set to grow strongly despite wave of cancellations and persistent challenges
Worldwide hydrogen demand increased to almost 100 million tonnes in 2024, up 2% from 2023 and in line with overall energy demand growth. The vast majority of this was met by hydrogen produced from fossil fuels without measures in place to capture associated emissions. Sectors that have traditionally used hydrogen, such as oil refining and industry, remained the biggest consumers.
The uptake of low-emissions hydrogen is not yet meeting the expectations set by industry and governments in recent years, especially in light of…

Space Cooling
Country and regional highlights
Updated energy efficiency standards and new policies target emissions associated with space cooling
CO2 emissions
Progress on efficiency and power decarbonisation have not been sufficient to curb emissions growth from rising space cooling demand
Energy
In 2022 energy consumption for space cooling further increased by more than 5% from 2021
Activity
More than half of floor area additions to 2030 will occur in areas of the world with a high need for space cooling

Methane Abatement
Global energy-related methane emissions remain near record highs
In recent years, many countries and companies have set targets to reduce methane emissions, with commitments now covering over half of global oil and gas production. However, methane emissions from the energy sector plateaued near record highs in 2025 – revealing a large implementation gap.
Still, there is significant scope for further action. Around 70% of fossil fuel methane emissions in 2025 came from the top 10 emitting countries. Meanwhile, the methane intensity of oil and gas production varies widely across countries – with the best performers scoring more than 100 times better…

Natural Gas
…to undergo major changes by the end of this decade. The unfolding coming wave of liquefied natural gas (LNG) production capacity is set to rebalance the global gas market, enhance energy supply security and improve the affordability of natural gas.
About 300 billion cubic metres (bcm) per year of LNG export capacity – a record – is set to be added by 2030, primarily supported by liquefaction capacity additions in the United States and Qatar. This expansion could translate to a net LNG supply increase of 250 bcm a year, which could drive prices lower and spur higher demand, according to forecasts.
