On Thursday evening, green lights gave the home of D.C. government, the John A. Wilson Building, a verdant glow—signaling that the city is in solidarity with Paris and the climate accords.

D.C. will keep working towards the goals of a historic global climate agreement, even as President Donald Trump announced on Thursday that the United States will withdraw from it.

“As the mayor of a major city, I have a special obligation to protect our environment for generations to come and to create policies and programs that reflect the values of the residents I serve,” Mayor Muriel Bowser said, adding that the city would work with other cities and countries towards the goals of the Paris Accord: a voluntary agreement to mitigate rising temperatures and greenhouse gas emissions.

Bowser is a member of the Climate Mayors, an initiative bringing together city leaders to tackle climate change issues. On Thursday, the group pledged to “adopt, honor, and uphold the commitments to the goals enshrined in the Paris Agreement. We will intensify efforts to meet each of our cities’ current climate goals, push for new action to meet the 1.5 degrees Celsius target, and work together to create a 21st century clean energy economy.”

A growing number of municipalities, universities and companies are trying to commit to the Paris Accord, even without Trump and the federal government on board.
