California's Global Warming Solution Act of 2006 mandates that facilities emitting more than 25,000 metric tons of carbon dioxide equivalents annually from stationary combustion must report emissions starting this year. This could affect public agencies that have diesel generators, landfill gas flares, wastewater digester gas combustion, water pump engines, and/or green waste grinders. It's also likely that the rule will be extended in the future to cover more specific sources — such as landfills.
