Greenpeace teams were out today around Copenhagen, lining various routes from the airport and through the city with a message for heads of state that politicians talk but leaders act. And we've followed them all the way to the parliament building where they're due to have dinner later this evening.
'Don't betray our children's future' was projected on the scaffolding at the top of the Folketing in English, German and Spanish to target many of the key dignitaries in their first or second languages.
Because the security is so tight around the parliament building right now, our photographer was only able to get so close to catch this picture but it's something for those leaders to think on as they tuck into their hors d'oeuvres.
