University of Michigan (U-M) researchers declare “considerably flawed” analysis led the United States Postal Service (USPS) to downplay the environmental advantages of electric mail trucks.

The Postal Service has used its analysis to justify not making its total fleet of next-generation mail trucks electric, which has drawn criticism from the White House, Congress, and environmental teams. U-M claims its researchers carried out a extra rigorous examine that also confirmed a a lot bigger emissions discount than the original analysis.

“U-M researchers carried out a cradle-to-grave greenhouse-gas emissions evaluation—generally known as a life-cycle evaluation, or LCA—of the 2 eventualities and reached some vastly totally different conclusions than the Postal Service did,” the college mentioned in a press launch. The LCA has a broader scope than the original USPS examine, which solely thought of emissions from precise use of the autos.

The debate over electrifying the USPS mail truck fleet began greater than 18 months in the past, with the surprise announcement that solely 10% of the USPS next-generation supply trucks can be electric. That led environmental teams and a coalition of states to sue the USPS.

The USPS gave into stress this summer season, and now plans for 50% of its preliminary procurement of the next-generation autos to be electric, and when mixed with different kinds of autos within the fleet, 40% will likely be electric.

U-M researchers seemed on the original plan of 10% EVs, evaluating it to an all-electric fleet. They discovered that greenhouse fuel emissions underneath the ten%-EV state of affairs can be 15% greater than estimated by the USPS, whereas emissions from an all-electric fleet can be 8% decrease than the USPS estimate.

The U-M examine additionally factored in estimated reductions in electrical energy grid emissions over the focused 20-year lifespan of the brand new mail trucks. The USPS examine appeared to imagine the grid will not get any cleaner than the current—however in fact it nearly actually will.

That makes an enormous distinction. With grid decarbonization estimates factored in, U-M researchers predict that an all-electric fleet would end in as much as 63% decrease greenhouse fuel emissions than the company estimated, over the lifetime of the fleet.

These findings counsel the USPS needs to be electrifying at a price a lot greater than even the raised 40% threshold, Greg Keoleian, senior creator of the examine, mentioned within the launch. The Inflation Reduction Act, which leads to an intensive revamp of the EV tax credit score and, for a time, a limited number of eligible EVs, included one other $3 billion towards USPS electric autos—so the second for a better dedication is now.
