Reducing Greenhouse Gas Emissions

Despite the addition of several energy-intensive facilities and processes — such as the Catskill-Delaware Ultraviolet Disinfection Facility, the Croton Water Filtration Plant, Combined Sewer Over ow facilities, and Biological Nutrient Removal — as mandated by federal and state authorities, DEP has reduced its greenhouse gas emissions by more than 20% since scal year 2006, with a goal of an 80% reduction by 2050, by pursuing a four-pronged strategy:

1.Demand-Side Solutions, including on-site energy conservation and ef ciency, on-site equipment and operational improvements, and citywide water demand management;

2. Supply-Side Solutions, including on-site clean energy generation using anaerobic digester gas (“biogas”), as well as other on-site bene cial uses of biogas;

3.Traditional Renewable Energy Solutions, including non-biogas renewable energies such as hydropower, solar photovoltaic systems, geothermal, and more; and

4.Energy and Carbon Offsets, including off-site bene cial use of biosolids and biogas, as well as carbon sequestration by green infrastructure, restored wetlands, and DEP-acquired forested lands.
