Fort Lauderdale Net Zero Plan 2025

APPENDIX A: METHODOLOGY  123

of the following (1) emissions reductions of the LA scenario, and (2) emissions reductions from strategy implementation. The quantitative GHG impact model used to showcase the City’s pathway to net zero uses 2019 as the baseline year. Impacts from each of the strategies in the Plan are calculated by assigning a percent reduction in underlying activity level (e.g., energy consumption, waste generated, miles traveled); a percent reduction in activity blended emissions rate (i.e., CO 2 e/MMBtu, CO 2 e/ton of waste); or both simultaneously compared to the BAU every 10 years, starting in 2030 and ending in 2050. The percent reduction in energy consumption assumed in the model, as a cumulative result of the actions within each strategy in the Plan, corresponds with the operating entity reducing its activity by that percentage, whether it be a reduction in energy usage , vehicle miles traveled, or waste processed. This would reduce the overall activity, which would in turn reduce GHG emissions to make progress toward the net zero goal. Assumed activity reductions are based on an assessment of each strategy’s reasonable reduction potential over time, as needed to achieve reductions for that strategy. The assigned percent reduction in the blended emissions factor corresponds to reduction in emissions for every unit of energy consumed by the activity. Rather than reducing the activity to reduce emissions, the entity can instead reduce its emissions by changing its source of energy to less carbon intensive sources. In the forecast modeling, this is considered separately from grid decarbonization, which is part of the LA scenario, and would require an entity to produce carbon-free energy on site or switch to alternative fuels to meet these projections. Reducing reliance on grid decarbonization and increasing power production on-site would improve the likelihood that the entity could sustain its activity needs while reducing emissions in the process. Strategy components that both reduce energy usage and blended emissions rate simultaneously (such as replacing a natural gas water with a more efficient electric equipment) are quantified by calculating emissions impact from a reduction in activity level and blended emissions rate simultaneously. Similar to reductions in activity consumption (energy, waste, etc.), reductions in blended emissions factors for each strategy are set based on reasonable reduction potential over time, based on an assessment of other cities’ climate action plans. Emissions reductions projections are quantified by adding strategy emissions impacts to LA impacts and calculating the remaining projected emissions for each year. For the purpose of tracking progress toward the City’s net zero goals, the remaining emissions are compared to the 2019 baseline emissions overall and for each sector.
