The State of California has been supporting regional climate change research for more than a decade. These studies have complemented research at the national level and have been designed to inform climate policy deliberations and actions in California. This Research Catalog provides basic information about past and ongoing climate change related studies that state agencies have conducted or commissioned since the early 2000s. The purpose of this catalog is to document California’s research efforts and to facilitate the exchange of information.

In this project, Lawrence Berkeley National Laboratory developed a carbon footprint modeling framework that characterizes the key underlying technologies and processes that contribute to household carbon footprints in California and the United States.
Assessment of Landfill Gas Monitoring Well Viability and Its Effect on Greenhouse Gas Emissions
Lead Agency: Cal Recycle
Principal Investigator(s): Raymond H. Huff, R.E.A.
(SCS Engineers, Inc)
Year finished: 2007, Budget: $153,625
Published/Product: http://www.calrecycle.ca.gov/publications/default.asp?pubid=1311 Notes
Research examines landfill gas (LFG) monitoring well functionality in California using data gathered at 20 landfills. Results used to assist the California Energy Commission in refining its GHG emission models.
Assessment of Residential Natural Gas Emissions
Lead Agency: CEC
Principal Investigator(s): Marc Fischer
(Lawrence Berkeley National Laboratory)
Year finished: 2017, Budget: $500,000
This is the first study designed to estimate the magnitude of residential methane leakage. Since results indicate that leakage from residential (and perhaps commercial buildings) may constitute a non-trivial fraction of California's natural gas-related methane emissions to the atmosphere, additional research is needed. A systematic study that quantifies leakage from residential structures in California including both single and multi-family buildings across potentially relevant explanatory factors (e.g., geographic region, size, age of construction, assessed value, and owner occupied vs. rental classes) will greatly reduce uncertainty in this area.
The objective is to analyze biomass and biogas resources and their integration into local fuel infrastructure in both urban and rural/agricultural environments, to determine the associated emissions of GHG and criteria pollutants, and to evaluate the potential air quality co-benefits of biomass and biogas use.
CONTRACTOR SHALL EVALUATE THE POTENTIAL AND CONSTRAINTS OF CARBON-NEUTRAL ELECTRICITY AND VEHICLE FUEL (HYDROGEN, BIOGAS) SUPPLY, BASED UPON REGIONAL RENEWABLE BIO-RESOURCES. TO PROVIDE A RANGE OF RENEWABLE BIO-RESOURCES, CONTRACTOR WILL FOCUS ON TWO DISTINCT REGIONS: THE SOUTH COAST AIR BASIN, AND SAN JOAQUIN VALLEY. CONTRACTOR WILL ANALYZE BIOMASS RESOURCES AND THEIR INTEGRATION IN LOCAL FUEL INFRASTRUCTURE IN THOSE REGIONS, DETERMINE NET EMISSIONS OF GREENHOUSE GASES AND CRITERIA POLLUTANTS, AND DETERMINE RESULTING AIR QUALITY IMPACTS.
Assessment of the Potential Environmental Impacts of Alternative Energy Scenarios for California
Lead Agency: CEC
Principal Investigator(s): Kammen, Dan
Year finished: 2014, Budget: $200,574
The proposed project will include an assessment of the environmental footprint of the energy scenarios identified in the California's Carbon Challenge report. The researcher will estimate the geographical footprint of the different energy technologies mandated by the scenarios. This will include not only the amount of land for energy development, but also assessment metrics to place these land demands into context, such as the ecological sensitivity of the area identified for future energy development. Similar efforts will be conducted to assess consumptive water demand; criteria air pollutant emissions, and climate change effects.
Association between Long-Term Ultrafine Particulate Matter Exposure and Premature Death
Lead Agency: ARB
Principal Investigator(s): Michael Kleeman
Year finished: 2014
The objective of the proposed study is to perform a state-of-the-science exposure assessment for UFPM’s based on measurements and regional models and to determine whether UFPMs are positively associated with premature death in California using an established epidemiological cohort.
ATMOSPHERIC INVERSE MODELING METHODS OFFER THE POTENTIAL TO ACCURATELY QUANTIFY CURRENT GHG EMISSIONS AND FUTURE REDUCTIONS, REDUCING UNCERTAINTY IN INVENTORY ESTIMATES. LAWRENCE BERKELEY NATIONAL LABORATORY (LBNL) WILL EMPLOY INVERSE MODELING BY COMPARING MEASURED AND PREDICTED ATMOSPHERIC GHG CONCENTRATIONS IN AN ANALYSIS THAT EXPLICITLY CONSIDERS SOURCES OF ERROR. SPECIFICALLY, LBNL WILL 1) CONTINUE AND EXTEND GHG MEASUREMENTS AT EXISTING LBNL MEASUREMENT SITES, 2) IMPLEMENT GHG MEASUREMENTS AT A NEW SITE THAT SAMPLES AIR REPRESENTATIVE OF THE RIVERSIDE AND SAN BERNADINO REGIONS, AND 3) APPLY AN INVERSE MODELING FRAMEWORK TO ESTIMATE GHG EMISSIONS FROM THE MAJOR EMISSION REGIONS OF CA. THIS FOCUSED RESEARCH WILL ENABLE CARB TO 1) CONTINUE AND INTEGRATE MEASUREMENTS OF THE FULL-SUITE OF GHGS (CO2, METHANE, NITROUS OXIDE, AND HIGH GLOBAL WARMING POTENTIAL GASES) AT THE SUTRO TOWER AND WALNUT GROVE SITES INTO THE CARB NETWORK, 2) EXPAND THE CARB MEASUREMENT NETWORK TO COMPREHENSIVELY SAMPLE GHG EMISSION SOURCES IN THE SOUTH COAST AIR BASIN, AND 3) CONDUCT COMPREHENSIVE INVERSE MODELING TO QUANTIFY CA’S CURRENT GHG EMISSIONS USING THE COMBINED MEASUREMENT ASSETS AVAILABLE FOR CA. THE PRODUCTS WILL BE A RIGOROUSLY DEFENSIBLE ESTIMATE OF ANNUAL TOTAL ANTHROPOGENIC GHG EMISSIONS AND A MEASUREMENT AND MODELING SYSTEM CAPABLE OF CONTINUING THOSE ESTIMATES INTO THE FUTURE.
