It uses an inventory scope and framework consistent with international and national GHG inventory practices. The inventory includes estimates for carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2O), and fluorinated gases with high global warming potentials (High-GWP) which includes hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF 6), and nitrogen trifluoride (NF 3). CARB is responsible for maintaining and updating California's GHG Inventory per H&SC section 39607.4. The inventory provides estimates of anthropogenic GHG emissions within California, as well as emissions associated with imported electricity natural sources are not included in the inventory. In concert with data collected through various California Global Warming Solutions Act (AB 32) programs, the GHG inventory is a critical piece in demonstrating the state's progress in achieving the statewide GHG target. Webinar Presentation Slides Ĭalifornia's annual statewide greenhouse gas (GHG) emission inventory is an important tool for establishing historical emission trends and tracking California's progress in reducing GHGs. Note: Carbon dioxide equivalent values are calculated using the IPCC's Fourth Assessment Report 100-year Global Warming Potential values. It provides easy-to-read graphs and explanations to illuminate California's progress in its commitment to reduce climate-changing emissions.Ģ000–2020 GHG Emissions Trends Report Data used for figures in the report is available for download. Links to additional data and documentation can be found below. The California Greenhouse Gas Emissions for 2000 to 2020, Trends of Emissions and Other Indicators, summarizes and highlights the major annual changes and notable longer-term trends of each year's GHG inventory.
