This indicator shows the San Diego's total annual greenhouse gas emissions citywide, combining emissions from buildings, transportation, waste, water, and wastewater. The green circles on the chart show the City's targets for total emissions reductions by 2030 and 2035.
The chart displays two separate lines rather than one continuous line. The first covers 2015–2019 and the second covers 2019–present, reflecting a refinement in how emissions are calculated between the City's 2015 and 2022 Climate Action Plans. Because the two methods produce slightly different results, there are two distinct data points for 2019 — one calculated using the older method, and one using the newer — which is why the lines do not connect.
