"President Trump today fired another volley in his all-out assault on our environment. His executive order rolling back the Clean Power Plan is a profoundly short-sighted swipe at our children's future. While the Environmental Justice Unit in my office will continue aggressively taking on polluters - and our City and State are in the vanguard of promoting forward-thinking environmental protections - today our nation took a giant step backwards. This is the moment we most need to combat climate change. Tomorrow will be too late."
