<p>CAPCOA developed methodologies for quantifying and analyzing greenhouse gas (GHG) emissions generated by proposed land use and infrastructure developments. The methodologies will be used to evaluate a development&rsquo;s contribution to global climate change for the purposes of environmental impact assessment. The analytical team devised methods and identified tools available for quantification of emissions generated by construction activities; vehicle trips associated with operation of proposed land use development; area-source emissions associated with on-site space heating, water heating, and landscape maintenance; and indirect emissions associated with energy consumption. The project involved providing strategic input about California Environmental Quality Act (CEQA) compliance requirements related to GHG analysis and mitigation. Additionally, evaluation of the applicability of the newly-developed analytical methods to different project types was performed and example calculations were provided. A quantitative threshold framework was established to determine whether proposed land use and infrastructure developments would be consistent with state-wide GHG reduction goals, while accommodating future projected growth in both the state&rsquo;s economy and population. The methodologies and metrics prepared will help local governments evaluate proposed development&rsquo;s potential to contribute to global climate change, under the context of CEQA. This work was presented in CAPCOA&rsquo;s CEQA &amp; Climate Change document released January 2008. Quality assurance reviews of the document were also conducted.</p>
