2010 Greenhouse Gas Emissions Inventory

The City conducted a municipal GHG emissions inventory in 2010 (using 2007 data) to create a baseline against which GHG emissions reductions can be calculated in order to show progress toward goals.

The inventory includes emissions from seven municipal sources.

The inventory revealed that 90.9 % of all municipal GHG emissions came from three sources and the largest source of our emissions is energy used in buildings, specifically for heat & hot water and electricity.

The remaining 9.1% of municipal GHG emissions came from the following 4 areas:
