Governor Ralph Northam has pledged to put $20 million from the Volkswagen diesel-emissions settlement toward the purchase of zero-emission school buses, the governor’s office has announced. The program, to be administered by the Department of Environmental Quality (DEQ), will help local school systems to replace about 75 diesel-fueled buses and reduce CO2 emissions by 36 million pounds per year, the administration says. It’s a nice little feel-good story. But, as I attempted to conduct some elementary cost-benefit analysis, I found that the numbers don’t make sense. And even if they did, there are probably more cost-effective ways to save the planet from the climate apocalypse. Here’s how it works. DEQ will reimburse local school systems up to $265,000 per electric bus, which is approximately the difference in cost between purchasing a diesel-powered bus and an electric bus. While the electric buses can save $2,000 a year in fuel costs and $4,400 and maintenance, the extra up-front investment is a big hurdle. The new program eliminates that barrier, creating financial savings for the locality and a reduction in CO2 emissions as well. So far, so good. How much in CO2 reductions w...
