Description: Map illustrates the 2020 emissions for stationary sources in the AB 617 International Border Community. Stationary emissions are composed of reported facility data (stationary point) and aggregated stationary sources. Stationary facilities emission data is based on Air District's report for annual emissions for permitted facilities. Stationary aggregate emission data presented in tons per year are based on the latest CARB State Implementation Plan emission inventory and are projected to 2020 using the most up-to-date growth and control factors at the regional scale. Stationary aggregate source emissions are distributed to more specific locations using the latest spatial surrogates resulting in high-resolution 1x1km emission grids for the community. Examples of spatial surrogates include population, housing, employment, land cover type, etc.
