How Cities are Tackling Climate Change

Inefficient buildings contribute to climate change, but mayors can help: “If we want to achieve what science tells us we need to—which is halving emissions by 2030 on the way to net zero at or before 2050—let’s start where the problem is, which is in buildings. If you step back, there are some really interesting innovations to drive change quickly. Under two mayors, New York has done really interesting work. Mike Bloomberg decided that he would require commercial buildings over a certain size to post their energy consumption so that their tenants would know what it was … And what Mayor Bill de Blasio did was pass an ordinance that required buildings to dramatically lower their greenhouse gas emissions between now and 2030.”
