In the next few months Gordon Brown will make one of the most important decisions of his career that will determine whether the UK pursues a high or low carbon economy.
If he gives the Kingsnorth coal-fired power station the green light, it will pave the way for a whole new generation of coal-fired power stations*.
Burning coal is the single biggest cause of climate change. Leaders of Friends of the Earth, Oxfam, Greenpeace, RSPB, WWF, Christian Aid, People & Planet, the Women's Institute and Tearfund have all signed the letter below calling on the Prime Minister to say yes to the massive scaling-up of clean, green energy and no to new coal plants like Kingsnorth.
We have enough wind, wave and solar energy to switch to green energy without the lights going off.
Don't let Gordon Brown lock Britain into decades of high carbon emissions. Join the leaders of our coalition by adding your name to this letter to Gordon Brown (using our handy form).
* Coal-fired power stations that have no means of capturing and storing their carbon dioxide emissions.
