Cars and Vans
…standards is important as even in the Net Zero Emissions by 2050 Scenario, nearly 80% of cars and vans on the road in 2030 are still powered with internal combustion engines. Sales of heavier, less efficient SUVs reached around 46% of global sales in 2022, while electric vehicles were just 14% of sales. More and more countries are formulating vehicle efficiency standards and some are even putting in place zero-emission vehicle sales requirements. To be in line with the Net Zero Emissions by 2050 Scenario, all car and van sales will need to be zero-emission by with 2035.

Electrification
Country and regional highlights
Electrification gains momentum across countries and sectors
CO2 emissions
In the Net Zero by 2050 Scenario, from now to 2030 most electrification-related emission reductions occur in transport
Energy
The share of electricity in energy demand will need to increase by 4% per year to get on track with the Net Zero by 2050 Scenario

Trucks and Buses
Electrification of road transport goes beyond cars and the ambition is growing
Globally, almost 50 000 electric buses were sold in 2023, equating to 3% of total bus sales and bringing the global stock to approximately 635 000 in total. Several European countries (such as Belgium, Norway and Switzerland) and China achieved sales shares above 50% in 2023, and more than one-fifth of bus sales were electric in Canada, Chile, Finland, the Netherlands, Poland, Portugal and Sweden.
Sales of electric trucks increased 35% in 2023 compared to 2022, meaning that total sales of electric trucks surpassed electric buses for…

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…

Energy Efficiency
11th Annual Global Conference on Energy Efficiency
The International Energy Agency’s 11th Annual Global Conference on Energy Efficiency is being co-hosted by IEA Executive Director Dr Fatih Birol and Canada’s Minister of Energy and Natural Resources Tim Hodgson on 29 and 30 June 2026. Hydro-Québec, a recognised leader in energy efficiency, will also help drive industry engagement at the event.
The 11th edition of the IEA’s landmark event comes at a pivotal moment. Many governments around the world are focused on stronger action on energy efficiency as a key policy priority in order to ensure…

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…
