Abstract
This paper describes the methodology and data used to determine greenhouse gas (GHG) emissions attributable to 10 cities or city-regions: Los Angeles County, Denver City and County, Greater Toronto, New York City, Greater London, Geneva Canton, Greater Prague, Barcelona, Cape Town and Bangkok. Equations for determining emissions are developed for contributions from: electricity; heating and industrial fuels; ground transportation fuels; air and marine fuels; industrial processes; and waste.
A simplified version of an intergovernmental panel on climate change (IPCC) method for estimating the GHG emissions from landfill waste is applied. 3 measures of overall emissions are suggested: actual emissions within the boundary of the city; single process emissions (from a LCA perspective) associated with the city’s metabolism; and life-cycle emissions associated with the city’s metabolism. The results and analysis of the study are published in a second paper.
