Check Out A Guerrilla Art Group's Great Takedown Of Corporate Sponsors At The Paris Climate Talks

These were not the ads the sponsors were looking for.

While President Obama and the leaders of more than 150 nations are meeting in Paris for the U.N. Climate Conference, the U.K.-based guerrilla art collective Brandalism has plastered the French capital with more than 600 fake ads "critiquing the corporate takeover of the COP21 climate talks," targeting the companies sponsoring the talks.

"Amidst the French state of emergency banning all public gatherings following the terrorist attacks on 13 November in Paris, the 'Brandalism' project has worked with Parisians to insert unauthorised artworks across the city that aim to highlight the links between advertising, consumerism, fossil fuel dependency and climate change," the group said in a statement.

The spoof ads targeting AirFrance, Volkswagen, Dow Chemicals and others were created by more than 80 artists from 19 countries across the world, including some who were featured in Banksy's Dismaland exhibit this summer. "By sponsoring the climate talks, major polluters such as Air France and GDF-Suez-Engie can promote themselves as part of the solution - when actually they are part of the problem," said Brandalism's Joe Elan.

In addition to taking on the sponsors, some of the posters are encouraging people to take part in the "Climate Games," described as "the world's largest disobedient adventure game."
