Air Quality/Non-GHG Emissions

In keeping with New York City’s goal of reducing GHG emissions, we are converting the generating equipment at our steam and electric generating stations. Currently, those stations burn No. 6 oil as backup fuel to natural gas. But we’re converting to No. 4 oil as backup fuel because it’s lighter and contains a lower concentration of criteria pollutants. All Con Edison units will be converted to have the capability to burn No. 4 oil by the winter of 2019–20 as required by Local Law 38.
