New York City has published a report claiming that its emissions of greenhouse gases (GHG) declined from 2008 to 2009. According to the report, the reductions put the city on track to meet its goal of a 30-percent reduction in GHG emissions below 2005 levels by 2030.  

The city reported emissions in 2009 of 49.3 million metric tons of carbon dioxideequivalent, a 12.9-percent reduction from 2005 levels and a 4.2-percent reduction from 2008 levels, even though the city’s population grew and the number of its buildings increased. The report attributes the reductions to less carbon-intensive and more efficient electricity generation, reduced per capita energy consumption and reduced emissions of sulfur hexafluoride. The targeted reduction goals are based on a long-term sustainability plan put in place by the city in 2007.
