California Gov. Jerry Brown signed an energy agreement with Mexican national officials promoting cross-border energy efficiency and renewable energy programs. Brown also signed a climate change agreement with Mexican national government officials in Mexico City to cooperate on initiatives to reduce greenhouse gas (GHG) emissions. “California and Mexico both take the low-carbon imperative with utmost seriousness, and [the state] cannot do it alone; with this new partnership with Mexico we can make real progress on reducing dangerous GHG emissions,” Brown said.
