The nation’s mayors sent a strong message to the Trump administration: If the federal government won’t take the lead on fighting climate change, they will.

At their annual summit that concluded Monday, the bipartisan U.S. Conference of Mayors, which represents more than 1,400 mayors nationwide, passed several resolutions pushing back against President Donald Trump’s policies on climate change. It included a call to Congress and the president to commit to environmental initiatives such as the Paris climate agreement and the Clean Power Plan. The country’s largest coalition of cities also passed a landmark resolution supporting cities’ transitions to 100 percent renewable energy by 2035. The resolution was passed unanimously, the Guardian reported.
