Environment and Climate Change
Making London greener, cleaner and ready for the future.
Our vision: building a greener London for everyone
London’s environment connects every aspect of life in the city. It is the air Londoners breathe, the water they drink and the parks where they meet and spend time. The state of London’s environment affects everyone who lives in and visits the city – it helps Londoners to stay healthy, allows businesses to thrive and keeps London functioning from day to day.
Our London Environment Strategy sets out an ambitious vision for improving London’s environment for the benefit of all Londoners, including:
- cleaning up the toxic air that damages the health of young and old alike
- creating new green spaces where they are needed most
- tackling the city’s environmental challenges.
By making new connections we're confident we will make London greener, cleaner and ready for the future.
