This translates to a 28 percent reduction in total Pleasanton GHG <br />emissions from 2005 to 2017, which exceeds the GHG emission target established in the 2012 CAP. <br />Table 18 summarizes GHG emission changes in Pleasanton from 2005 to 2017, and Table 19 <br />summarizes changes in activity data.49 Between 2005 and 2017, Pleasanton reduced GHG emissions in <br />every sector except for nonresidential gas, which may have increased due to growth in development of <br />the commercial and industrial sectors within the City. Major GHG emissions reductions were achieved <br />in the waste and wastewater sectors, although these sectors make up smaller proportions of overall <br />Pleasanton emissions as shown in Figure 4. It is worth noting that large GHG emissions reductions from <br />electricity usage were driven largely by PG&E’s electricity fuel mix, which saw a significant decrease in <br />carbon intensity50 from 2005 to 2017. Although there was an increase in passenger vehicle miles <br />traveled (VMT), GHG emissions associated with the passenger on-road transportation sector declined <br />because of the increased fuel efficiency of vehicles as detailed in Tables 18 and 19.18 <br /> <br />49 Table 17, Table 18, Table 19, and Figure 4 may present data in different ways, but they are summarizing the same data. On-road <br />transportation includes both passenger and commercial on-road transportation. <br />50 Carbon intensity is the amount of carbon by weight emitted per unit of energy consumed. For example, as the percentage of renewable <br />energy sources used to produce electricity increases, the carbon intensity of that electricity decreases.
