A recent report by the California Air Resources Board claims that the state’s plan to reduce global warming emissions will save consumers $14 billion in fuel costs, thanks to increased fuel efficiency. But according to an article in the Orange County Register by policy analyst William Yeatman, the costs have been underestimated, while the benefits are overblown. For starters, the California board used the highest possible estimate for future gas prices, even through increased fuel-efficiency would lower the price of fuel. In addition, since lower fuel costs are an incentive for more driving, this plan would likely increase air pollution and traffic in California cities, and would even lead to more deaths on the highway due to lighter cars.
