A coalition of environmental groups has sued the state’s air pollution regulator over its recent, contentious changes to a core climate program — the state’s Low Carbon Fuel Standard — that they say is exacerbating climate change. Just a month earlier, California Republicans had attacked the same policy, saying it would cause higher gas prices.

The groups, which include San Joaquin Valley residents, filed two lawsuits on Wednesday in Fresno County Superior Court. One lawsuit seeks to force the California Air Resources Board to cut pollution from large farms that make biogas from manure, which the fuel standard program encourages. It’s led by the environmental justice group Defensores del Valle Central para el Aire y Agua Limpio.
