The legislation, which now heads to the Democratic governor's desk, would require steep reductions in a variety of climate-changing gases known as short-lived climate pollutants, including methane, HFC gases used in aerosols and air conditionnts and soot, known as black carbon. While these pollutants live in the atmosphere for relatively short periods, they have an outsized impact on climate change, according to legislative researchers.
"With this bill we prove again that California doesn't shy away from tackling major climate change legislation. We lead," said Sen. Ricardo Lara, D-Bell Gardens, who wrote the bill and brokered the compromise with the dairy industry.
The compromise package, tied to $50 million in methane emissions funding, would set a requirement that dairies and livestock producers reduce methane emissions from manure to 40 percent below their 2013 levels by 2030. It allows for the regulation of cow flatulence — another source of methane emissions — if experts determine that technology exists to reduce it.
California would also be pushed to significantly increase composting in order to reduce organic waste, which emits greenhouse gases when it breaks down in landfills. SB1383 sets a goal of reducing the flow of food products to landfills by 50 percent within four years.
