The San Diego County Board of Supervisors on Wednesday voted unanimously to rescind a plan that was widely panned by environmentalists and ultimately rejected by the courts.
The Sierra Club's, Mike Bullock, said the county's first try at meeting state standards for greenhouse gas reductions just fell short.
"They said they would have a plan that's enforceable and that they would achieve some important state-mandated climate targets and it turned out they did not do that," Bullock said.
Bullock said the vote represents an opportunity for the county to develop an effective plan that reduces the region's carbon footprint with other communities using it as a model.
Besides concerns about transportation, environmentalists want the county to consider energy efficiency and renewable energy, and they want the plan to deal with development and the ability to adapt to changing conditions.
Nicole Capretz, the executive director of the Climate Action Campaign, said everyone has a stake in a successful effort.
"At the end of the day, climate change is one of the greatest risks to our future, and especially for the future of our kids and grandkids," Capretz said. "That's why it's incumbent on us. It's incumbent on the county to do the right thing, and to make this a plan that's enforceable."
State officials gave all municipalities until 2035 to have 100 percent of the power coming from renewable sources and they have until 2050 to dramatically reduce greenhouse gas emissions.
