London mayoral election: Who said what on the environment?

"Air quality is a national disgrace. London is facing fines of around £300m because of it. We can’t wait a minute longer to take real action."

"Solar is becoming more efficient by the day, for reasons we all now know well - I will do everything in my power to support London’s clean energy."

"Our transport system is becoming more overcrowded every year... It’s becoming increasingly difficult to sustain London’s water and energy supplies."

"I want my daughters to grow up in a city that is cleaner and greener, in which people aren't dying because the air is so filthy."

"As Mayor, I will set up a new London Energy Company to ensure that Crossrail is powered by 100% clean electricity."

"The debate on environmental issues has gone off the rails; it has been polarised too much and everybody is hearing the same message: doom and gloom."

"We need a new electric car charging network with at least 25,000 charging points for cleaner vehicles, including the new taxis."

"I will expand the use of solar across the city, and support communities who want to set up their own green energy generation schemes."

"Making London an attractive place for walking and cycling is vital and I have no hesitation in advocating the pedestrianisation of Oxford Street."

“Heavy vehicles will be banned from inner-London in daylight hours. London will be a 24-hour city, with a 24-hour tube.”
