Methane, a potent greenhouse gas that traps about 30 times more heat than carbon dioxide, is commonly released from rice fields, dairies, landfills, and oil and gas facilities—all of which are plentiful in California. Now the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has been awarded $6 million by the state to find "super emitters" of methane in an effort to quantify and potentially mitigate methane emissions.
