California Wildfire Emissions: Summary Graphs
This webpage contains key graphs associated with California’s Wildfire Emission Inventory. For additional information about the methodology and data sources, or to download data or explore the data in an interactive map, see the main California Wildfire Emission Estimates webpage for more information.
Notes:
- These graphs represent vegetations burned in wildfires. CARB staff is currently developing a new emission inventory pipeline for estimating emissions of structures and automobiles burned in wildfire. The new data are expected to be available in late 2026.
- The numbers in these graphs include all fire events in the CAL FIRE Fire History Geo-database. They include "Wildland Fire Use (WFU)," which refers to fires that are managed to accomplish specific pre-stated resource management objectives in predefined geographic areas outlined in fire management plan.
- There are slight differences in scope of coverage in the time series. CARB revamped the methodology in the 2025-2026 inventory cycle and reanalyzed 2015-2023 using new methodology but could not reanalyze 2000-2014 due to limitations in input data from non-CARB sources. As a result, 2000-2014 include only natural land types (e.g., forest, shrubland, grassland), while 2015-2024 include all land types (adding agricultural and developed lands).
