CITY OF PLEASANTON CLIMATE ACTION PLAN UPDATE measure implementation progress. By reviewing what measures from CAP 1.0 have been successful and why, our team can tailor the CAP 2.0 measures to the specific hurdles and successes found in the first CAP iteration. We will analyze emissions on both a gross and per-capita basis to illustrate how population changes may have affected the overall change in Pleasanton's emissions, consistent with state guidance in SB-32. (In order to account for population changes,the state has shifted towards establishing per-capita emissions targets.) Pleasanton's significant growth in recent decades—from a population of 51,000 in 1990 to over 83,000 in 2017—would likely make achieving GHG reduction targets on a gross basis unrealistic. Additionally,to the extent that the 2017 inventory makes this data available,we will also evaluate emissions reductions at the scope, sector,and policy/program levels.We will reference these findings when updating the City's reduction targets; if granular data is available,we will also incorporate the results into our criteria weighting and/or evaluation of potential new strategies(see Tasks 6 and 7). For example, if the 2017 inventory shows significant progress in reducing transportation emissions but emissions growth in the solid waste sector,we can dig into the reasons behind the divergence and focus on improving solid waste reduction policies in the CAP 2.0. Deliverables: • Draft and final GHG inventory peer review and progress-tracking memo • Updated GHG inventories(if required to improve consistency or resolve methodology problems) Task 3a — Vulnerability & adaptation assessment While reducing emissions is the City's dominant focus, it is also important to acknowledge that climate change is already having local impacts—from increased heat and wildfire risk to changing precipitation patterns—and that these impacts will only become more severe,even if emissions are sharply curtailed.Therefore, it will be valuable to include an assessment of the community's vulnerability to current and projected climate impacts and review potential adaptation opportunities.As part of this task, Cascadia will review existing documents related to climate impacts such as the local Hazard Mitigation Plan and the California Climate Change Assessment technical reports;we will draw from this research to form a clear picture of the top climate-driven threats in Pleasanton and how they are likely to change in the coming decades. Once we have established the city's most severe climate impacts,we will assess vulnerability by weighing sensitivity— that is, how severe a potential impact will be—against adaptive capacity,or how feasible it is to lessen the severity of a given impact.Those impacts with high sensitivity and high adaptive capacity will likely present the greatest opportunities for cost-effectively reducing Pleasanton's vulnerability, as they seriously impact the community but can be addressed in a relatively straightforward manner. Deliverables: • Draft and final memo summarizing local vulnerability and adaptation opportunities, including a ranking of adaptation actions based on sensitivity and adaptive capacity Task 4— Update the City's emissions forecast Using our team's customizable emissions forecasting model, along with relevant information from the existing GHG emission inventories,we will forecast"business as usual"("BAU")scenarios for community-level emissions in Pleasanton for 2025, 2030, 2045, and 2050,consistent with SB-32, B-55-18, and S-3-05.These years have been selected based on a combination of State goals and interim milestone years (such as 2025)which will help in short- term planning and measure selection. We will build the BAU scenarios to address the most significant emission sources, including energy, building, mobility, waste, and sequestration, unless otherwise determined in collaboration with the client team.
