Norway wants to be a world environmental leader at a key UN meeting next week -- but the government is backing a dirty investment that could mean game over for the climate, and it’s up to us to stop them.

Norwegian giant Statoil is a major player in the Canadian tar sands, one of the dirtiest and most carbon-intensive fuels known. In fact, the tar sands contain so much carbon that extracting it would be a death sentence for the planet. But Statoil is two-thirds owned by the Norwegian state, and the government can order the company to stop this disastrous project.

In days, Prime Minister Jens Stoltenberg will arrive at a crucial meeting of heads of state in Rio de Janeiro to trumpet Norway’s climate leadership to the world. So let’s raise our voices before he gets there to ensure he stops this dirty investment and doesn’t tar our climate reputation. Sign the petition -- it will be delivered to the media when 10,000 people have signed -- and send this to everyone you know.
