choices) that are relevant to reductions in greenhouse gas emissions from transportation12. <br />Examples of relevant initiatives include the Safe Routes to Schools Program and pursuit of <br />Bicycle Friendly Community standards. Key partners include NCDOT, the Durham - Chapel <br />Hill - Carrboro Metropolitan Planning Organization, Triangle Transit, Chapel Hill Transit, UNC, <br />and the Carrboro Bicycle Coalition. <br />Conclusion #1: At this juncture it is difficult to assess how transportation emissions have <br />changed and could change over time. In addition, the community based method which is limited <br />to trips in Carrboro is not able to capture changes associated with community members' larger <br />transportation behaviors and choices. A helpful step for tracking changes /reductions in <br />transportation emissions for future community inventories could be the development of a new <br />dataset and methodology. Confidence in emissions estimate is less than in the buildings sector <br />where energy use data is more directly measured through metered utility accounts. <br />Conclusion #2: Carrboro has been involved in important initiatives that have reduced greenhouse <br />gas emissions from transportation for the past 1 -2 decades, and has established plans, dedicated <br />resources and partners, and community capacity to continue with these efforts. Vehicle MPG has <br />also steadily increased for several decades. This also is in some contrast to the situation with <br />emissions associated with buildings. All things considered, it seems reasonable that the <br />transportation sector may have a stronger foundation in historical emissions reductions, however, <br />as discussed, additional work is required to more accurately assess historical emissions and <br />assess what might be possible for reductions by 2025. <br />Renewable Ener�y <br />The North Carolina Sustainable Energy Association ( NCSEA) tracks renewable energy <br />installations in North Carolina. Based on the NCSEA estimate of 268 kilowatts (kW) of <br />renewable energy generation (via photovoltaics, or "PV ") for 52 installations in Carrboro, the <br />total PV generation as of 2016 is a little under I% of the total electricity demand. A <br />considerable majority of the solar capacity in Carrboro was installed in 2014 and 2015 as part of <br />back -to -back "Solarize" campaigns13. To make significant progress towards the 50% emissions <br />reduction target by 2025, renewable generation will have to ramp up quickly. <br />What is a reasonable estimate of the maximum amount of solar electricity that can potentially be <br />generated in Carrboro based on physical realities of terrain, solar insolation (available sunshine), <br />and the nature of the built environment? It can be inferred, hypothetically, by extrapolating from <br />an estimate included in the Chapel Hill greenhouse gas inventory14, that 3% of Carrboro may be <br />suitable for solar installations from rooftops, open land, and parking lots, and a total of 116k <br />megawatt hours (MWh) of potential annual energy generation could mitigate up to 8 1 k <br />" These documents are available at biqi: / /www.townofc irrlioro.orL. 719 / "FrLinsLiorfiaE:ion <br />13 hfl�EC�:/ /solarize- nc.orp /IocaE:ions/ <br />14 hflE:p:/ /ie.unc.cduLFilcs /2016 /0:1 /communiEy carbon re.�f (p.21) <br />FA <br />
