Following President Donald Trump's decision to withdraw the U.S. from the historic Paris climate agreement, everyone from former president Barack Obama to most of Twitter has condemned the move.
In an effort to protest the decision, many political and business leaders from around the world have confirmed their support of the international pledge to address global warming. On Thursday night, that support was highlighted by a number of city halls, monuments and landmarks, which lit up in green in solidarity with the Paris accord.
In the French capital, where City Hall glowed green, Anne Hidalgo, Mayor of Paris, said cities will stay committed to saving the environment, "regardless of Trump's decision."
New York Governor Andrew Cuomo tweeted that the One World Trade Center and the Kosciuszko Bridge had been lit green in solidarity.
City Halls in Boston and New York followed suit. "City Hall shines green tonight because New York City will honor the goals of the #ParisAgreement," Mayor Bill de Blasio tweeted.
The Wilson Building in Washington, D.C., turned green "in honor of D.C.'s continued commitment to the #ParisAgreement #ClimateMayors," Mayor Muriel Bowser said.
Mexico City and Montreal were among the other cities to join in.
