Greenhouse gas emissions declined in Sonoma County in 2011 for the third straight year, reflecting an expansion of renewable energy sources and a down economy, which lowered demand for power and transportation.
Still, Sonoma County's goal of reducing emissions 25 percent from 1990 levels by 2015 remains elusive, officials said Tuesday.
The annual report card by the Climate Protection Campaign was presented at the Sonoma County Strategies for Sustainability, a conference that drew 160 people from government, industry and the public to discuss better environmental practices.
"We have to try harder," said Michael Kyes, Sebastopol's vice mayor, who was attending the conference.
Setting such a lofty goal is important, even if it might not be met, said Gary Helfrich, executive director of the Sonoma County Bicycle Coalition.
