But can’t an EV purchaser take pride that his car reduces global warming? Well, not really. A study last year by the Norwegian University of Science and Technology
found that, for a vehicle with a 100,000 kilometer lifetime (when batteries would need replacement), EV environmental impacts were “indistinguishable from those of a diesel vehicle.” The reason is that manufacture of an EV emits about double the carbon dioxide required to manufacture a diesel or gasoline car, primarily to build the metal batteries of the electric.

The study also found that “EVs exhibit the potential for significant increases in human toxicity, freshwater eco-toxicity, freshwater eutrophication, and metal depletion impacts, largely emanating from the vehicle supply chain.” In other words, production of electric car batteries may become a major source of pollution. Suppose we go slowly on promoting electric cars, Mr. President?
