Short summary
Methane and carbon dioxide emission rates were calculated for facilities across several sectors in New York State using aerial observations. Of the sampled facilities, landfills dominated the methane emission rates, while combustion facilities had the highest carbon dioxide emission rates, followed by landfills. The self-reported Environmental Protection Agency (EPA) inventory mostly underestimates landfill methane emissions, apart from a few facilities with comparable numbers.
