Mayor Bill De Blasio Pledges to Cut New York Carbon Emissions by 40% by 2030

Bill de Blasio, the mayor of New York City, has pledged to reduce his city’s carbon footprint by 40% by 2030. de Blasio followed Pope Francis's lead, invoking the pope's call on the world to take bold action on climate change.
The remarks were presented at a rare Vatican meeting of mayors from around the world who gathered to discuss the environmental challenges facing their cities and the correlation between global warming and modern slavery. De Blasio, who arrived at Vatican City a few hours late after his flight from New York was diverted by fog, said it had become “painfully obvious” that political leaders had to set “difficult goals for ourselves” in the fight against global warming.
