Paris is grabbing the world's attention again, but this time, it's with environmental messages aimed at the world leaders, including Obama, that gathered for the COP21 climate conference on Monday. 600 fake posters denouncing major corporations were installed behind the glass at bus stops around the city by Brandalism, a UK-based project. 82 artists from 19 countries joined them to help fight corporate control in advertising.

"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," Joe Elan from Brandalism said in their press release.

"Because the advertising industry force feeds our desires for products created from fossil fuels, they are intimately connected to causing climate change," Elan said. "We are taking their spaces back because we want to challenge the role advertising plays in promoting unsustainable consumerism."
