Fort Lauderdale Net Zero Plan 2025

124  APPENDIX A: METHODOLOGY

Cost Analysis High-level carbon abatement costs expressed in dollar per metric ton of carbon dioxide equivalent ($/MTCO 2 e) were obtained from sources including the International Energy Agency, the World Bank, and publicly available cost data from similar initiatives in other cities. The $/MTCO 2 e cost was then applied to the projected annual carbon reductions relative to the legislative-adjusted baseline for 2025 through 2030. These cost estimates are intended to provide rough amounts to facilitate initial implementation planning efforts. More precise costs should be obtained as the details of implementation efforts are filled out. For community-focused strategies, the data available to quantify costs borne by the City were limited. These estimates are derived using the abatement costs outlined above multiplied by the percentage expected to be borne by the City, supplemented by labor cost estimates expressed in full-time equivalent hours for city personnel and vendors. This approach is intended to communicate the level of coordination and planning required for community actions and initiatives. These costs are also quantified at the strategy level. Qualitative estimates for costs borne by the community are included at the action level. While the overall GHG impact of strategies is estimated at both the municipal and community level, cost estimates provided in this Plan focus exclusively on the anticipated costs to the City at the strategy level. Community strategies also include a qualitative estimate for costs borne by the community. Assumptions and Limitations To forecast GHG emissions under multiple scenarios, several assumptions were required. This section provides an overview of the assumptions and limitations of the modeling used in this Plan. Although Fort Lauderdale has been tracking GHG emissions since 2010, the City selected 2019 as its baseline year for its net zero goals because 2019 was one of the first years that offered improved data for its inventory, particularly in the transportation sector. The GHG emissions report for 2019 encompasses scopes 1, 2, and a limited subset of scope 3 emissions. Chapter 2 of this report defines emission scopes. It is important to note that additional non-energy emissions not directly related to energy production or consumption have not been included in the baseline inventory and are therefore not accounted for in the modeled projections. Among these, hydrofluorocarbons are of particular concern because of their widespread use and significantly higher global warming potential compared to carbon dioxide. Commonly used in air conditioning, refrigeration, and spray cans, the EPA closely monitors and regulates hydrofluorocarbons. For future emissions outlined in the BAU scenario, change over time was calculated based on historical population, activity, and economic data fluctuations between consecutive years. This
