Info

Employee commuting is an important government operations sector that could not be incorporated in to this report due to restrictions on data. Emissions from employee commuting are scope 3 emissions generated when employees combust fossil fuels commuting to and from government facilities. Other local governments who were able to quantify employee commute emissions found that this sector is normally one of the largest emitting sectors, comprising between 20 and 30 percent of total emissions. While local governments do not directly control how employees commute, County policy can have a significant impact in encouraging employees to use alternate modes of transportation to commute. Community Inventory Results In 2005, the San Diego County community emitted approximately 4,197,665 metric tons of CO 2 e. As shown in Figure ES.2 and Table ES.2 below, the transportation sector was by far the largest source of emissions, generating approximately 2,909,342 metric tons of CO 2 e, or 69 percent of total 2005 emissions. Transportation sector emissions are the result of diesel and gasoline combustion in vehicles traveling on both local roads and state highways that pass through the jurisdictional boundaries of San Diego County.

Electricity and natural gas consumption within the commercial / industrial sector, the second greatest source of 2005 emissions, generated 615,687 metric tons CO 2 e, or 15 percent of the total. Similarly, electricity and natural gas use in unincorporated San Diego County’s residential sector produced 505,963 metric tons CO 2 e, or 12 percent of total community emissions. The remaining four percent of emissions are from methane released by landfills in the base year, and from the estimated future methane emissions that will result from the decomposition of solid waste and wastewater that was generated by the San Diego County community in the base year.
