  • Solid Waste
  • Water
  • Wastewater

Modernizing the City’s approach to monitoring progress achieving a net zero goal, moving forward we will measure progress towards “0” rather than measuring against a historic baseline¹. This will ensure the monitoring results are more transparent and consistent with the most current available information, and also easier to understand so that the public, stakeholders and decision makers can independently assess the City’s progress and budgeting of resources.

¹ The data presented uses the most up-to-date calculations of greenhouse gas emissions and inventories within our Climate Action Plans. Climate action progress and projects often rely on estimated assessments where previous records do not exist. Therefore, revisions are made frequently to previous publications to ensure data is as accurate as possible, especially when computational models improve, and recalculation provides updated information. The City of San Diego currently collaborates with the Energy Policy Initiatives Center – University of San Diego (EPIC) to develop analysis used in climate policy and planning efforts.
