2017 GHG Emissions Inventory <br /> <br />Pleasanton Climate Action Plan Update 19 <br />Off-Road <br />Off-road emissions were calculated using the California Air Resources Board’s OFFROAD2007 modeling <br />tool.45 At the time of this inventory, the 2017 version of the tool was still not available. OFFROAD2007 <br />was used to obtain emissions for Alameda County, shown below in Table 9. The proportion of <br />emissions attributed to the City of Pleasanton was based on a ratio for effective change in service <br />population, calculated to be 0.0806, using demographic data from the Department of Finance. The <br />effective change in service population was calculated by taking the sum of new population and jobs in <br />Pleasanton from 2016-2017 and dividing by the total sum of new jobs and population in Alameda <br />County for 2016-2017. No change or decreases in a jurisdiction’s demographic data were counted as <br />zero. Demographic data used is shown below in Table 10. Total emissions from off-road transportation <br />in 2017 was 58,852 MT CO2e, shown in Table 11. <br />Table 9 Estimated Off-Road Emissions for Alameda County 2017 <br />Source CO2/day CH4/day N2O/day MTCO2e/year <br />Agricultural Equipment 44.49 0.004043 0.000570 14,819.72 <br />Airport Ground Support Equipment 52.53 0.005930 0.003753 17,777.87 <br />Construction and Mining Equipment 1,181.69 0.101368 0.007014 392,841.72 <br />Dredging 0.00 0.000000 0.000000 0.00 <br />Entertainment Equipment 2.61 0.000115 0.000000 865.80 <br />Industrial Equipment 292.98 0.088145 0.016153 99,248.92 <br />Lawn and Garden Equipment 77.83 0.115765 0.050340 31,262.29 <br />Light Commercial Equipment 159.90 0.041037 0.025518 55,567.60 <br />Logging Equipment 0.00 0.000000 0.000000 0.00 <br />Military Tactical Support Equip 0.00 0.000000 0.000000 0.00 <br />Oil Drilling 2.11 0.000153 0.000000 698.51 <br />Other Portable Equipment 0.04 0.000003 0.000000 13.94 <br />Pleasure Craft 63.54 0.041389 0.013664 22,621.27 <br />Railyard Operations 0.04 0.000002 0.000000 11.67 <br />Recreational Equipment 11.18 0.096323 0.016988 6,087.09 <br />Transport Refrigeration Units 182.23 0.014037 0.001260 60,581.77 <br />Total 2,071.17 0.508310 0.135259 702,398 <br />MT CO2e: metric tons of carbon dioxide equivalent; VMT: vehicle miles traveled <br /> <br />45 California Air Resources Board. 2007.
