94 <br />Orange County GHG Inventory <br />3 2005 GHG INVENTORY <br />The inventory section of the report provides estimates of the GHG emissions within the <br />communities as a whole and emissions produced by local government operations. in the baseline <br />year 2005. In the sections below, emissions from each module (community and local government) <br />are broken down into five different sectors to provide a detailed analysis of each module. This <br />model of categorizing emissions into modules and sectors follows the Cities for Climate <br />protection (CCp) protocol which has been developed to facilitate and standardize emissions <br />inventories that take part in the CCP program. It is important to note that the local government <br />operations module is a subset of the community module and to add them together would be <br />double- counting emissions. <br />3,1 Community Inventory <br />3.1.1 Overview <br />The community inventory provides an estimate of all of the GHG emissions produced within <br />Orange County both by residents in their homes and by local businesses and agencies as they <br />carry out their operations. Five key sectors are included in the community inventory: residential, <br />commercial/institutional, industrial, transportation, and solid waste. <br />During 2005, Orange County (including Carrboro, Hillsborough and Chapel Hill) produced <br />approximately 2,777,281 tons of GHGs. Table 3 provides a summary of the energy used and GHG <br />emissions produced by each of the sectors. Figure I provides an illustration of the contribution to <br />emissions from each sector. The transportation sector was the largest contributor to total <br />emissions, responsible for 48% of the GHG emissions produced within the county. This was <br />followed by the commerciaVinsiitutional sector (29 %) and the residential sector (20 %). The <br />industrial sector (2 %) and solid waste sector (1 %) contributed a relatively small amount to total <br />emissions. <br />5 Numbers may not add correctly because of rounding. <br />Orange County GHG Inventory and Local Action Plan Document 23 <br />
