The California Air Resources Board, California Energy Commission, and California Public Utilities Commission
invite you to a Joint Agency Symposium and Integrated Energy Policy Report Workshop:
Methane Emissions from California’s Natural Gas System: Challenges and Solutions.


New!!! June 6-7 Symposium Audio Recording:

Audio recordings of the presentations are available here.


Sessions will focus on methane emissions from natural gas systems and discuss the options offered by current science and technology to detect, measure, and reduce emissions related to the natural gas used by California consumers:

    ·    ARB and CEC/CPUC Research Priorities and Needs
    ·    Current and Upcoming Methane Emissions Research
    ·    Current and Emerging Technologies to Detect and Measure Methane Emissions
    ·    Policy Panel Discussion on Potential Legislative, Regulatory, and Mitigation Actions
    ·    Showcase of Methane Detection and Measurement Technologies


To bring industry, academics, government and non-government entities, and other interested stakeholders together to:

    ·    Discuss the current understanding of methane emissions across the natural gas supply chain 
    ·    Share ideas to increase knowledge and inform policies
    ·    Foster stakeholder interaction on current research and promote dialogue for next steps 

An in-depth look at methane emissions and reduction opportunities related to California’s consumption of natural gas is important given California-based initiatives to reduce methane emissions, federal methane regulations introduced in 2015, and Governor Brown's emergency proclamation on the gas leakage at the Aliso Canyon Natural Gas Storage Facility.  The symposium will help support several state programs such as:

    ·    2030 Greenhouse Gas Target Scoping Plan 
    ·    2016 Integrated Energy Policy Report Update 
    ·    Short-Lived Climate Pollutant Strategy (SB 605)
    ·    Low Carbon Fuel Standard
    ·    CPUC proceedings on natural gas transmission and distribution (SB 1371)
    ·    Requirements to study methane hot spots and conduct life-cycle greenhouse gas emissions of natural gas produced and imported into California (AB 1496)
    ·    Strategies to maximize benefits of natural gas, including biomethane, as an energy source (AB 1257)
    ·    Environmental Justice policies
    ·    Coordinated state response to leakage at the Aliso Canyon Natural Gas Storage Facility

NEW!!! Research Opportunities:

If you are interested in submitting a research idea for the Board's consideration, you can do so through our website here.  ARB's annual research plan is designed to address the Board's priority research needs.  The Board is primarily interested in projects that will assist in addressing the future reserach needs in the general areas of Health and Air Quality Standards, Exposure Assessment, Technology Advancement and Pollution Prevention, and Global Climate Change.  

You may also sign up for the ARB Research Activities listserv here and you will be sent a notice when ARB has solicitations for specific project proposals.
