Friends of the Earth have launched an online march asking for a strong climate law, as Thom Yorke mentioned earlier. On the FOE website you can upload a video to ask your MP about that law.
Thom Yorke has posted a video where he reminds Gordon Brown that he’s “committed to a bill to reduced C02 emissions double quick time. And if he doesn’t: it will come down on him like a ton of bricks.”
If you want to join the march, check the Friends Of The Earth website for more information.
