Biofuels
Country and regional highlights
The United States Inflation Reduction Act makes USD 9.4 billion available for biofuels
Energy
Biofuel demand increased by 6% in 2022, continuing the recent pace of growth
Technology deployment
Biofuel production technology needs to diversify to sustainably take advantage of existing waste and residue feedstocks
Innovation
Technologies that can convert woody feedstocks into biofuels need to be proven at scale in the next few years

Direct Air Capture
Country and regional highlights
The United States is leading the race on policy support for DAC
CO2 capture
DAC plants currently operate on a small scale, but with plans to grow
Energy
How can we capture CO2 directly from the atmosphere?
Innovation
A small but growing DAC technology portfolio is emerging
Supporting infrastructure
DAC deployment for carbon removal relies on the availability of low-carbon energy sources and CO2 storage
Policy
Government support for DAC is growing in major markets

Gas Flaring
CO2 emissions
The volumes of natural gas flared in 2022 were around the same level as in 2010
Technology deployment
Oil producers have a range of readily available options to reduce and avoid flaring, with a number of new technologies also under development
Policy
A number of countries have introduced policies to reduce flaring
Investment
Operators that sell high-flaring assets are often passing on a problem to other operators that may be less willing, or less able, to cut down on flaring

Paper
Country and regional highlights
There is growing ambition on electrifying heat in the European paper industry
CO2 emissions
Emissions intensity has seen a decade of reductions, but further effort is needed going forward
Energy
Further energy efficiency improvements and fuel switching are needed to get on track with the Net Zero Scenario
Activity
While production has been relatively flat over much of the past decade, growth in emerging economies may drive a moderate increase in the coming years

Aluminium
Country and regional Highlights
Technological progress is being made in a range of countries, while the expected expansion of China’s emissions trading systems will be key to reducing direct emissions
CO2 emissions
Further action to reduce emissions intensity will be needed to get on track with the NZE Scenario
Energy
While the energy efficiency of aluminium production has improved, fuel switching needs to accelerate

Bioenergy
Led by bioenergy, renewable fuels could approach 6% of energy demand from industry, buildings and transport in 2030
By 2030, renewable fuels are set to account for 5.5% of energy consumption from the industry, building and transport sectors. Demand is due to expand in all regions, but it is concentrated in China, Brazil, Europe, India and the United States, which collectively support more than two-thirds of the forecasted growth. All five countries and regions have dedicated support policies for several – and, in some cases, all – renewable fuels. These vary by fuel, sector and country, but they often include…

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…

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…
