President Trump announced he was pulling the U.S out of the Paris agreement on climate change, Thursday. Several city governors and mayors reacted by lighting buildings up green to symbolize that they disagreed with his decision, according to reports.

Several city governors and mayors reacted to the President’s decision by lighting buildings with green to show their disagreement. US cities situated on the east coast and even some places outside the U.S including Paris adopted the symbol.

Green is used to represent the color of the environment. The Governor of New York was one of the first to hit Twitter, he tweeted a photo of the Kosciuszko Bridge, BBC reports.
