World leaders in Copenhagen failed to deliver the agreement necessary to keep us safe from climate change. In response Greenpeace is mobilising the largest movement civil society has ever witnessed, to demand a fair, ambitious, legally binding climate treaty.

Use their action below to show your solidarity.

Current EU commitments to 20% emissions cuts (based on 1990 levels), rising to 30% if a strong global deal is agreed, are simply not enough.

The target for the EU needs to be at least 40% if we want to avoid the danger level of a 2°C rise in global warming. Please write to Gordon Brown using his CAFOD action asking him to put pressure on the other EU leaders to sign up to the required 40% emissions reduction.

The RSPB's Letter to the Future will be used to hold politicians to account over climate change and the destruction of our environment, so the more names, the more impact!

The UK needs to commit to a minimum of 40% emissions reductions (based on 1990 levels) to stand a 50:50 chance of avoiding global temperature rises exceeding the danger level of 2°C.

Use Friends of the Earth's action to write to Ed Miliband, Secretary of State for Energy and Climate Change, to demand the UK commits to at least 40% reductions and puts up more money to help those people who will be hit first & worst by the effects of climate change.

COP15 ended so badly, Christian Aid want you to write to Gordon Brown asking him to get the negotiations up and running again.
