California's new ambitious greenhouse gas reduction targets.
Yesterday California Governor Jerry Brown issued an executive order establishing the state's greenhouse gas reduction target 40 percent below 1990 levels by 2030 (Executive Oder B-30-15). This new executive order is another step reducing California's greenhouse gas emissions after the California Global Warming Solutions Act of 2006 (AB 32) which set reduction targets to 1990 levels by 2020. LBNL models predict we're on target to meet the 2020 goals but will need more effort ot meet the ultimate 2050 goals.
Research in this area demonstrates that to achieve 80% greenhouse gas reductions by 2050 that moving to low-carbon and renewable energy will be important, but also investment in carbon capture and sequestration (CCS) technology. Integrated climate protection into planning and land use policies, such as smart growth planning, will also help California meet its targets. Much of the technological innovations to cut greenhouse gas emissions by 2050 hinges on the role of electricity to move away from carbon based fuels across economic sectors. And yes, high-speed rail could also be part of the solution.
