Consumers are still buying diesel engines, even though more fuel-efficient choices exist, writes an Automotive News reader in a letter to the editor.…

Jayant Kairam, director of global public policy for Walmart, said while government policies should promote “technology-neutral” pathways to decarbonizing transportation, a major investment in charging infrastructure for heavy-duty vehicles is nonetheless necessary to realize enough GHG cuts.
Meanwhile, Allen Schaeffer, executive director of the Diesel Technology Forum, said vehicle electrification is not a “one-size-fits-all” solution, and urged the audience to “not lose sight of the near-term opportunities” for biofuels that can work with existing infrastructure and engines.
“EVs may not be the perfect solution for all applications,” Schaeffer said, noting that switching diesel engines to biofuels brings immediate drops in GHGs. “We should value carbon reduction however we can get it,” Schaeffer said, noting the longevity of diesel engines, which currently account for 76 percent of commercial vehicle engines in the country.
Schaeffer further noted ways in which diesel technology and battery technology can work together, such as with hybrid engines or diesel generators as backup for EV charging stations using renewable power.
