8% is the amount that New York City's greenhouse-gas emissions have risen between 1995 and 2005.

58.3 million tonnes is the amount of greenhouse gas emitted by the city in 2005 — almost as much as the entire Republic of Ireland, but just 1% of total US emissions.

2.7% is the proportion of the US population that lives in the city — making New Yorkers almost three times greener, on average, than the typical American.
