The Healthy Waterways initiative brings together 15 London boroughs and partners to cut air pollution along canals and rivers. Working with boaters, it tackles emissions from diesel and solid fuels through awareness campaigns and a long-term strategy for cleaner air and sustainable waterways.

Wood burning is now one of the biggest sources of harmful air pollution in London. It contributes around 15% of the city’s PM₂.₅ emissions, tiny particles that can damage lungs, trigger asthma, and even increase risks of heart disease and dementia. The London Wood Burning Project brings boroughs together to raise awareness, support enforcement, and help residents choose cleaner alternatives to domestic wood burning.

Since 2019, the Cleaner Construction for London team has worked with contractors and suppliers to audit over 3,700 sites. Specialist inspectors visit construction sites and have directly assessed more than 10,000 machines.
