David Cameron is about to decide whether or not to accept the targets recommended by his own climate change experts. The prime minister promised to stick to these targets and to lead “the greenest government ever,” but now there’s a real danger that he will break that promise.

We need to make sure our MPs are telling David Cameron to listen to the experts and to keep his promise. If we all email our MPs right now, we can send a powerful message.
