Reducing the human carbon footprint is a "moral imperative," University of California President Janet Napolitano said Tuesday as she vowed to turn the system's 10 campuses into a living laboratory for solutions that can be scaled up to state, national and global levels.
Napolitano made the comments at a two-day climate change summit at UC San Diego, where researchers are discussing their blueprint for actions that they say the state and the world should undertake to tackle the problem -- including reducing the carbon footprint of the wealthiest 1 billion people.
The plan will be presented at next month's landmark climate change conference in Paris.
UC officials say global warming could be slowed dramatically by reducing greenhouse gases such as methane emissions by 50 percent and black carbon by 90 percent over the next 15 years. The wealthiest need to cut back dramatically, while green energy needs to be made more available to the poorest 3 billion people, the plan says.
UC experts are asking religious leaders to help foster change.
"Addressing these challenges and reducing our carbon footprint is a moral imperative," Napolitano said, adding that the university system is on track to meet its goal of becoming carbon neutral by 2025.
"I anticipate that by 2025, when the University of California is carbon neutral, that the rest of the world in seeking climate solutions will say, `Well, let's go back to 2015 when they had that summit at UC San Diego and let's see if we can do what the University of California did,"' said Napolitano, the former Homeland Security secretary and governor of Arizona.
The university has reached an agreement to buy 80 megawatts of solar power, the largest such purchase by any U.S. university, Napolitano said. UC also has vowed to target $1 billion of its investment portfolio toward renewable energy and other climate change solutions over the next five years.
If the world reduced its carbon dioxide emissions by 80 percent by 2050, that could slow the disastrous impacts of climate change by 25 years, UC researchers say.
Gov. Jerry Brown, who also spoke at the summit Tuesday, said the problem requires bringing together the state's best minds to cross partisan lines and move the nation away from relying on fossil fuels.
"We up against a very powerful opposition," Brown said, referring to Republican opponents who have blocked drastic carbon-reducing measures that they say will harm job growth.
Brown said denying climate change will hurt the economy in the end by causing the planet irreversible damage. He told the audience of mostly scientists that he recently sent Republican presidential hopeful Ben Carson, a neuroscientist, a flash drive containing the U.N. Synthesis Report on climate change after Carson said he has not seen evidence of global warming.
Brown has set some of the nation's most ambitious goals against global warming, including reducing the state's carbon dioxide emissions to 40 percent below 1990 levels, shifting its electricity production to at least 50 percent from renewable sources and increasing energy efficiency in buildings by 50 percent. He has called for the goals to be met by 2030.
"While California is not a planet, it is a global leader," Brown said. "What we do will be disseminated. It'll spread."
