Here\u2019s how the system works: The state\u2019s climate regulations require the transportation fuels industry to lower the carbon dioxide levels in its products over time\u2014or purchase credits from other parties that cut fuel emissions, including cattle farmers.<\/p>\n
Dairies generally spray cattle manure into giant open lagoons, where microbes gobble up organic matter and produce methane as a by-product. But if farmers set up what are known as anaerobic digesters, the sludge is redirected into covered vessels that capture the biogas, which can be converted into natural gas and injected into a pipeline. It can then be used to fuel certain vehicles or generate electricity in a power plant. Either way, petroleum companies can pay those farmers for Low Carbon Fuel Standard (LCFS) credits, to meet regulatory requirements in lieu of reducing the emissions from their own fuels.<\/p>\n
Burning biogas in a bus or turbine still releases carbon dioxide, but the idea is that this process reduces market demand to extract natural gas from the ground and avoids the release of methane, which is a far more powerful greenhouse gas (at least initially). In fact, methane is so much more powerful that under California\u2019s program, \u201cadding one average biogas-powered vehicle to the fleet would produce enough LCFS credits to cover the deficits incurred by 26 similar gasoline-powered vehicles,\u201d according to Aaron Smith, a UC Berkeley economist.<\/p>\n
But there\u2019s a problem with this carbon math. California assumes that methane exerts about 25 times the warming effect of carbon dioxide over a 100-year period. That\u2019s not how it really works in the atmosphere, though.<\/p>\n
Methane is very powerful, but it also breaks down quickly, generally within a couple of decades. Meanwhile, carbon dioxide builds up cumulatively in the atmosphere\u2014and much of whatever we emit will continue heating up the planet for hundreds to thousands of years.<\/p>\n<\/p><\/div>\n
