Last week, President Biden made a major environmental announcement that his administration will be largely restoring Obama-era vehicle fuel economy standards through 2025, which had been rolled back under the Trump administration. It’s a big deal because 30% of the country’s greenhouse gas emissions come from transportation.

Beyond restoring the standards, the president directed his agencies to develop more stringent standards beyond 2025 model years, for light- as well as medium- and heavy-duty vehicles. The goal should be 50% of new vehicles sales as zero emission in 2030.

To discuss the announcement, I appeared on KQED Forum on Tuesday and KTVU Channel 2 News in the San Francisco Bay Area last week. The radio audio is linked above and I’ve included the KTVU video below.
