The workshop, held Aug. 9 at the Fair Oaks Community Center in Redwood City, was the first of three planned to help the county try to figure out how to reduce greenhouse gas emissions in unincorporated areas to 1990 levels. The reduction, mandated by a state law passed in 2006, must take place by 2020.
The effort is being helped along by a federal Department of Energy grant of $350,000, which is being used to develop what the county is calling an Energy Efficiency Climate Action Plan.
The information gathered in the process will be used to update parts of the county's general plan and zoning code with policies and programs that will reduce greenhouse gas emissions.
Matthew Seubert, the county planner who is heading the program, called ReCharge San Mateo County, said the county has already found some ways of reducing greenhouse gas emissions. The county has adopted "green" building ordinances that encourage practices that cut energy use, and any new public buildings must conserve energy.
Some public buildings now have solar panels and the county has banned polystyrene food containers in unincorporated areas. County employees are encouraged not to drive to work alone and there is a county-wide recycling program.
Nora De Cuir of PMC, the consultants who have been hired to help with the ReCharge project, promised that the result of the study will not just sit on a shelf. "In day-to-day activities in the county, it will be used," she said.
The ReCharge program concerns only unincorporated areas of the county. Incorporated cities and towns must come up with their own plans to meet the state's requirements.
PMC has already determined the amount of greenhouse gases that existed in the county's unincorporated areas in 2005, the base year for the project. They measured carbon dioxide, methane, nitrous oxide and fluorinated gases (such as hydrofluorocarbons) and came up with just under a million metric tons of the gases.
They also determined where those gases come from. The biggest sources were transportation (52 percent), commercial energy (17 percent) the landfill (13 percent) and residential energy (10 percent).
That leaves the county with the goal of trying to figure out how to make its transportation, building, water, waste, and energy systems more efficient. Completion of the ReCharge project is scheduled for October 2012.
Ms. De Cuir, the PMC consultant, said that decisions about which methods will be used to reduce greenhouse gases will include looking at how much each action will reduce gases, how much it will cost, other benefits it will provide, and what funding sources will be available.
