Environmentalists are expected to face off with oil company officials at a legislative hearing Monday on continuing Oregon's clean fuels program.
Environmental groups want the Legislature to extend the Oregon Clean Fuels Program beyond its current expiration in 2015. The move would allow the state to go beyond a reporting requirement and begin forcing fuel providers to reduce the amount of greenhouse-gas emissions.
Oil companies and large-volume fuel users say the state is moving too fast and risks raising fuel costs significantly.
Oregon was one of the first states to approve a low-carbon fuel standard in 2009, requiring fuel producers to reduce the carbon content of their fuel by 10 percent from their 2010 levels. The Environmental Quality Commission has created a pollution-reporting mandate but has not fully implemented the standard.
