In a striking move just a day into his tenure, Department of Transportation Secretary Sean Duffy has made it abundantly clear that his agency will not address the significant impact of vehicle pollution on the escalating crisis of climate change. In a recent memo dispatched to the National Highway Traffic Safety Administration, Duffy has advocated for a thorough reassessment of fuel economy standards, aiming to align with President Donald Trump’s agenda of promoting fossil fuels, including oil, natural gas, and biofuels. The memo argues that the current fuel economy standards are “artificially high,” which, according to Duffy, has rendered new vehicles unaffordable for many American consumers and poses a potential threat to the US auto industry.
This development marks yet another significant shift in policy as the leadership in the country transitions again. During Trump’s first presidency, there was a notable rollback of the fuel efficiency standards that were previously put in place by Barack Obama. In contrast, when Joe Biden took office, the Environmental Protection Agency (EPA) introduced its most stringent standards ever. Prior to the current administration’s policies, Trump’s transition team hinted at a reversal of the previous administration’s efforts to enhance fuel efficiency standards and encourage the adoption of electric vehicles. While this recent announcement is not unexpected, it is particularly concerning given various international reports highlighting that the planet’s rising temperatures will lead to severe and catastrophic weather events.
