Environmental issues in New York City are affected by the city's size, density, abundant public transportation infrastructure, and location at the mouth of the Hudson River.
New York's population density has environmental pros and cons. It facilitates the highest mass transit use in the United States, but also concentrates pollution. Gasoline consumption in the city is at the rate the national average was in the 1920s,[1] and greenhouse gas emissions are a fraction of the national average, at 7.1 metric tons per person per year, below San Francisco, at 11.2 metric tons, and the national average, at 24.5 metric tons.[2] New York City accounts for only 1% of United States greenhouse gas emissions while housing 2.7% of its population.[2] In September 2012, New York was named the #1 "America's Dirtiest City," by a Travel+Leisure readership survey that rated the environmental quality of 35 prominent cities in the United States. Governors Island in New York Harbor is planned to host a US$1 billion research and education center poised to make New York City the global leader in addressing the climate crisis.[3]
