8.D. - Page 75 <br /> Calculatinq Emissions <br /> In general,err�issions can be quantified in twv way�. <br /> 1. Measurement-based methodologies refer to the direCt measureinent of greenhouse gas eini�sions from a <br /> monitoring sy�tem. Emissions measLned this way may include those errritted from a flue of a pow�r plant, wastewater <br /> treatment plant, landfill, or industrial facility. This method is the most accurate way of inventorying eini�sions from a <br /> given source,but is generally available for only a few sources of emissions. <br /> 2. Calculation-based methodologies refer to an estii�ate of einissions CalCUlated b�sed upon meas�'able activity <br /> data and emission factors.Table 3 provides exai�les of corninon ernissions calculations. <br /> Table 5: Basir_ Fmissinns Calr_ulatinns <br /> � � � <br /> Electrici Cons tion(ldlowatt hours) COzemitted/kWh COz emitted <br /> Natural Gas Cons 'on(therms) COz emitted/therm COz emitted <br /> Gasoline/Diesel Cons 'on( ons) COz emitted/ on COz emitted <br /> Waste GeneratedbyGoverninent Operations <br /> (tons) CH4 emitted/ton of waste CH4 errritted <br /> The Scopes Framework <br /> This inventory reports greenhouse gas erni�sions by sector and additionally by"scope", in line with the LGO Protocol <br /> and WRI/WBCSD GHG Protocol Corporate Standard <br /> Scope 1: Direct err�issions from soLnces within a local governinent's operations t1�at it owns and/or controls, with the <br /> exception of direct COz emissions from biogenic soLnces. This includes stationary combustion to produce electricity, <br /> steam,heat,and poww�rr equipment;mobile combustion of fuels;process emissions from phy�ical or chemical processin� <br /> fugitive err�issions tl�at result from production, processing, transrr�ission, storage and use of fuels; leaked refrig+erants; <br /> and other soLnces. <br /> Scope 2: Indirect emissions associated with the consLnnption of purchased or acquired electricity, stearr� heating, or <br /> coolin� <br /> Scope 3: All other emissions soLnces tl�at hold policy relevance to the local governinent that can be meastned and <br /> reported. This includes all indirect emissions not covered in Scope 2 that occur as a result of activities within the <br /> operations of the local governinent. Scope 3 erni�sion soLnces include (but are not limited to) tailpipe erni�sions from <br /> employ�e coininutes, ernploy�e business travel, and emissions resulting from the decornposition of governinent- <br /> generated solid waste. <br /> I I ' � ii i 1 i i i i <br />
