On Monday, California Governor Jerry Brown signed a bill mandating that the state's utilities move to 100-percent zero-emission electricity generation by 2045. Brown also issued an executive order today requiring the state to become carbon neutral by 2045, that is, mandating that the state remove as much greenhouse gas from the atmosphere as it puts into the atmosphere. One of the most interesting aspects of the zero-emissions bill signed today is that it also specifies that California can't increase the carbon emissions of another state to get cheap electricity. It appears that buying electricity from a coal plant in Nevada is fine if that electricity had been supplied prior to the bill's passing, but seeking out new out-of-state natural gas-fired plants to buy from would not be allowed. The bill's ambitiousness is compounded by the executive order that Gov. Brown signed today. The order requires California to become carbon neutral by 2045. "The achievement of carbon neutrality will require both significant reductions in carbon pollution and removal of carbon dioxide from the atmosphere, including sequestration in forests, soils, and other natural landscapes," Brown's executive order states (PDF).
