Cleaning up transport is one of the most pressing challenges of our time. It is the only major sector in which emissions have grown since 1990, making it a key contributor to the air pollution and climate emergencies.

But cleaning up transport is possible, and many of the tools to do this already exist in cities – we just need the political will to implement them.

By donating to the Clean Cities Campaign, your contribution will go to our hosting organisation Transport & Environment and ensuring that campaigns like ours continue to provide the evidence and momentum to decarbonise transport in Europe.
