"In California, forestry is the only sector that has a positive effect on air quality," says Sierra Pacific Industries
Mark Harmon, professor of forest science at Oregon State University, echoed CBD's criticisms, calling SPI's claims misleading and scientifically invalid. Harmon was quoted in CBD's lawsuit saying: "Harvesting forests generally reduces carbon stores and results in a net release of carbon to the atmosphere."
While the science remains unsettled, CBD claims progress. Three years ago, the organization convinced the state to conduct greenhouse gas analyses. "Now," Nowicki said, "[we've] established that these analyses need to be there."
