Boston City Hall Was Lit Green For Environment, Walsh Says

Boston City Hall was lit green Thursday night, showing that "Boston stands with the environment," Mayor Marty Walsh said.

Earlier Thursday, President Trump announced the nation would withdraw from the Paris climate accord. Walsh and many other mayors across the country said they would work to reduce emissions, despite Trump's decision.

"We must protect our future," Walsh said in a tweet.

Other city halls were lit up as well, including in Paris and New York City.
