We can make a greener, more liveable London and expand Heathrow

London can still become a world-leading green city with a third runway at Heathrow as long as it backs solar roofs, electric cars and a bigger congestion zone

The next mayor of London needs to be committed to making our city a better place to live; both more affordable and greener. The high cost of renting, public transport and low wages are one side of the challenge' while the need to reduce CO2 emissions, tackle air pollution and offer new sources of green jobs are the other.

Across the world, many other cities and countries are tackling the challenge with much more speed. London cannot afford to be left behind in this new global competition for more liveable cities.
