Staff Meeting on
Improved Greenhouse Gases Inventory Methods for
The California Energy Commission staff, in coordination with staff from CalRecycle and the California Air Resources Board, will sponsor a meeting to report on the results of a research project designed to develop a new model to estimate methane emissions from California landfills.

Staff at the Energy Commission, CalRecycle, Air Resources Board, and stakeholders will meet with the project's principal investigators, Dr. Jean Bogner of Landfills+, Inc. and Dr. Kurt Spokas from the U.S. Department of Agriculture, to discuss the results of a research project funded by the Energy Commission's Public Interest Energy Research (PIER) Program. This project developed a user-friendly model for annual methane emissions inclusive of seasonal soil moisture, temperature, and methane oxidation rates in daily, intermediate, and final cover materials. The investigators measured seasonal methane emissions from daily, intermediate, and final cover materials at landfills in California and completed complementary laboratory studies to assist with the development and field validation of the model. The freely-available California Landfill Methane Inventory Model (CALMIM) is currently being Beta-tested by a number of California users. Options for full implementation of the model after the completion of the Beta testing will be explored.
Accurate estimates of greenhouse gas emissions are an integral part of fulfilling the mandates of the California Global Warming Solutions Act of 2006 (Assembly Bill 32). Existing emission inventory methodologies for several source categories, including landfills, are currently being improved. Landfills are one of the major sources of methane emissions in California. Methane is a potent greenhouse gas with 25 times the global warming potential of carbon dioxide on a 100-year timeframe. To accurately quantify landfill emissions, consideration must be given to key variables such as site-specific cover materials and methane oxidation in daily, intermediate, and final cover materials, which is related to seasonal temperature and moisture variations. Improving the methane emission inventory for California landfills is an important step towards achieving a more accurate overall greenhouse gas inventory for the state.
