As mayor aims to win third term, what has he achieved so far on air pollution, the climate crisis and nature?
When Sadiq Khan launched his campaign for a third term as Labour mayor of London, he put his green policies front and centre, highlighting his work on air pollution, the climate crisis and nature.
For seasoned Khan watchers, this came as little surprise. The mayor, who last year published a book called Breathe: Seven Ways to Win a Greener World, has been widely praised for his work tackling air pollution, as well as his efforts on nature restoration and getting London to net zero by 2030.
The introduction and expansion of the ultra-low emission zone, which excludes the most polluting vehicles from the capital and has contributed to roadside N02 emissions dropping by 50%.
The introduction of thousands of new electric buses and taxis, and the continued expansion of the cycle network and promotion of walking.
A rewilding programme that has reintroduced a range of species, including beavers, expanded green spaces, and included a mass tree-planting programme.
