In the run up to the 15th United Nations Climate Change Conference (COP15) that takes place in Copenhagen next week, you’ll currently see a number of billboard ads on Copenhagen airport from an advertising campaign commissioned by Greenpeace. The ads feature photoshopped images of world leaders in 2020, apologizing for their mistake to decline necessary measures to stop climate change.

“It’s an apology from the future aimed at putting pressure on – and just maybe making these world leaders think twice about the consequences of their action or inaction now,”

explains the writer of the ads Toby Cotton of new agency Arc Communications.

“The brief from Greenpeace International was simple,” he continues, “to put pressure on world leaders to create a fair and binding agreement at Copenhagen.”
