Greenhouse Gas Inventory Report

A greenhouse gas (GHG) inventory/carbon footprint calculation was completed for calendar year 2010.  This is the third consecutive year that the District has calculated its carbon footprint.  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 2010 Greenhouse Gas Inventory, the District’s total GHG emissions for calendar year 2010 are 4,757 metric tons (MT) of carbon dioxide equivalent or CO2e. To put this amount into context, the District's total GHG emissions for 2010 are roughly equivalent to the amount of emissions that would be produced through the annual electricity consumption by 583 typical residential households.

The District's inventory for 2010 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 2,665 MT CO2e which represents 56% of total 2010 emissions.
