04/22/2013 As shown above, the two largest categories of emissions are related to transportation (highway travel, local travel, and off-road equipment) and building energy use (both residential and commercial & industrial). 2.1 Electricity and Natural Gas Emissions In 2005, electricity and natural gas use for buildings and facilities accounted for 48 percent of Redwood City's total emissions. Residential buildings accounted for 15 percent (99,144 MTCO2e), commercial/industrial facilities (including municipal facilities)accounted for 22 percent (149,810 MTCO2e), and direct access energy use accounted for 10 percent (68,542 MTCO2e). Direct access is when end use customer buys electricity or natural gas on the wholesale market, rather than from PG&E. Of the total 317,496 MTCOZe emitted, 53 percent (169,446 MTCO2e) was the result of electricity consumption, and 47 percent (148,050 MTCO2e)was the result of natural gas consumption.

The GHG emissions associated with electricity use is based on an emissions factor specific to PG&E's territory and is calculated annually by PG&E and then made available to Cities. The source of the emission factor used for the 2005 baseline inventory is the PG&E Power/Utility Protocol (PUP) spreadsheet of the PG&E California Climate Action Registry Report. In future inventory years, the emission factor may be found in the Additional Optional Information tab of PG&E's Electric Power Sector report spreadsheet, which is part of PG&E's Report to The Climate Registry. PG&E's specific emissions factor is calculated by dividing PG&E's total emissions from their power plants (in pounds of CO2) by the total amount of 34 RESO.#15258 MUFF#205
