While the federal government continues to tangle with Congress over a climate-change law, the California Air Resources Board on Dec. 16 endorsed its own cap-and-trade regulation.
The measure sets a statewide limit on the emissions from sources responsible for 80% of California’s greenhouse-gas emissions and establishes a price signal needed to drive long-term investment in cleaner fuels and the more efficient use of energy, according to CARB. The regulation is designed to provide covered entities with the flexibility to seek out and implement the lowest-cost options to reduce emissions.
