Greenhouse Gas Inventory Report

In 2009, a greenhouse gas (GHG) inventory/carbon footprint calculation for calendar year 2008 was completed. To create the GHG inventory, the General Reporting Protocol developed by the California Climate Action Registry (CCAR) was used. As indicated in the report, titled 2008 Greenhouse Gas Inventory, the District’s total GHG emissions for calendar year 2008 are 5,378 metric tons (MT) of carbon dioxide equivalent or CO2e. To put this amount into context, the District's total GHG emissions for 2008 are roughly equivalent to the amount of emissions that would be produced through the annual electricity consumption by 660 typical residential households.

The District’s inventory for 2008 included GHG emissions from all the electricity, natural gas and fuel used in the District’s operations including: groundwater pumping and supply, reservoirs and storage tanks, surface water supplies, fleet, administration and other buildings, capital improvement projects, small equipment, employee commuting, and air travel. By far the largest contributing emissions category for the District is groundwater pumping and supply emissions at 3,801 MT CO2e which represents 71% of total 2008 emissions.
