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…

Electric Vehicles
Global electric car sales continue to break records as affordability improves
Despite recent economic headwinds that have put pressure on the auto sector, global sales of electric cars have continued to break records as electric models become increasingly affordable. Electric car sales exceeded 17 million globally in 2024, reaching a sales share of more than 20%. Just the additional 3.5 million electric cars sold in 2024 compared with the previous year is more than the total number of electric cars sold worldwide in 2020.
In 2025, sales of electric cars are expected to surpass 20 million, accounting for over…

Chemicals
Country and regional highlights
Important steps to deploy low-emissions chemicals production technologies are being taken in several regions
CO2 emissions
CO2 emissions must decouple from production by 2030 to get on track with the NZE Scenario
Energy
Energy consumption for feedstock will continue to rise with production, but process energy intensity declines rapidly in the NZE Scenario
Activity
Primary chemical production is set to keep growing in the NZE Scenario
Innovation

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

Coal
Global coal demand to remain on a plateau in 2025 and 2026
Despite unusual trends across several major markets in the first half of 2025, global coal demand is likely to remain broadly unchanged to 2027 as underlying structural drivers of the world’s coal use remain stable.
Global coal demand increased to a new all-time high in 2024 of around 8.8 billion tonnes, up 1.5% from 2023, as rising consumption in China, India, Indonesia and other emerging economies more than offset declines in advanced economies in Europe, North America and northeast Asia. However, several of those…

Electrolysers
Country and regional highlights
Progress is spread across different continents, from China, which leads on installed capacity, to the European Union, which have adopted important policies, and other regions like India and the Middle East moving forward with a small number of large-scale projects
Technology deployment
Global installed electrolyser capacity reached 1.4 GW at the end of 2023, almost double the one at the end of 2022

Nuclear Power
A new era for nuclear energy beckons as projects, policies and investments increase
As the world’s second-largest source of low-emissions electricity after hydropower, nuclear power today produces just under 10% of global electricity supply. Now, fresh momentum around the world has the potential to open a new era for nuclear energy.
Power generation from the global fleet of nearly 420 active nuclear reactors is set to reach a record high in 2025 as Japan restarts production, maintenance works are completed in France, and new reactors begin commercial operations in various markets, including China, Europe, India and Korea…

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…

Behavioural Changes
Country and regional highlights
Governments have supported or mandated behavioural changes in buildings and on roads
CO2 emissions
Behavioural changes can quickly reduce CO2 emissions
Activity
Growth in activity is inevitable as economies develop and populations increase, but behavioural changes can help to offset these increases
Policy
Russia’s invasion of Ukraine and the resulting energy crisis have increased the salience of behavioural changes
