Municipal Energy Use & GHG Emissions

DCAS Energy Management oversees New York City's municipal energy accounts and greenhouse gas (GHG) emissions reduction initiatives in partnership with all City agencies. In this role, DEM is leading the effort to meet the City's ambitious goal of reducing its energy consumption and GHG emissions 30% by 2017, as described in the New York City's long-term sustainability plan, PlaNYC.

A 30% reduction from 2006 translates into 1.05 million metric tons of greenhouse gas reductions annually by 2017. This estimate is based on updates to the FY 2006 GHG emission baseline in the 2013 Inventory of New York City Greenhouse Gas Emissions.  The greenhouse gas emission reductions will come from several different sectors of government operations, illustrated in the pie chart below.

DEM’s programs fall into four main categories:

Managing City
Energy Accounts

Building Efficiency

Clean & Renewable Energy


The Department of Transportation manages GHG emission reductions from energy efficiency upgrades to street lighting; the Department of Sanitation manages GHG emission reductions from solid waste following the City's Solid Waste Management Plan; and the Mayor’s Office of Environmental Coordination manages GHG emission reductions from new construction.
