Welcome to the European Commission’s web page on transport decarbonisation. Here, you can discover our ongoing efforts to reduce greenhouse gas (GHG) emissions across the road, aviation, and maritime sectors. With transport accounting for more than a quarter of the EU's GHG emissions, taking swift action to decarbonise this sector is essential for achieving climate neutrality in Europe by 2050.
Transport represents almost a quarter of Europe's greenhouse gas emissions and is the main cause of air pollution in cities.
Discover what the EU is doing to tackle CO₂ emissions from road transport.
International shipping is a large and growing source of greenhouse gas emissions. We support global action to tackle these emissions.
Aviation is one of the fastest-growing sources of greenhouse gas emissions. We want to reduce aviation emissions in Europe and beyond.
