Mike Bloomberg made New York City a global leader in fighting climate change and pioneering sustainability measures, while also building hundreds of acres of new parkland and re-opening major areas of the waterfront that had been abandoned by industry decades ago.


NYC became a national leader in combating climate change and was on schedule to reduce the city's carbon footprint by 30% by 2030.

NYC established the nation’s most comprehensive sustainability plan, including a new national model for Green Building Codes.

In 2013, NYC's Citi Bike system was the largest bike share program in the country.
