Light trucks overwhelm EVs' carbon-cutting benefits to date

Electric vehicle sales have grown rapidly over the past several years. In 2012, only about 53,000 EVs were sold in the United States, counting both battery electric and plug-in hybrid models. By 2018, the annual tally of new EVs sold in the United States reached 361,000. It then tapered to 327,000 in 2019, the last full year of data before the 2020 pandemic. The vast majority of EVs are Teslas, with the big jump in 2018 due to the introduction of the Tesla Model 3. With overall light vehicle sales on the order of 17 million per year (pre-pandemic), EVs comprised about 2% of the U.S. market as of 2019.

The challenge is quite real when the market is pulling one way while regulations are pulling another.

Nevertheless, environmental need -- and indeed policy-fostering public sentiment to address global warming -- does not go down when pump prices fall.
