Researchers discover authentic USPS evaluation on electrical mail vans “considerably flawed”

College of Michigan (U-M) researchers declare “considerably flawed” evaluation led the USA Postal Service (USPS) to downplay the environmental advantages of electrical mail vans.

The Postal Service has used its evaluation to justify not making its total fleet of next-generation mail vans electrical, which has drawn criticism from the White Home, Congress, and environmental teams. U-M claims its researchers performed a extra rigorous examine that also confirmed a a lot bigger emissions discount than the unique evaluation.

“U-M researchers performed a cradle-to-grave greenhouse-gas emissions evaluation—often 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 stated in a press launch. The LCA has a broader scope than the unique USPS examine, which solely thought-about emissions from precise use of the autos.

The controversy 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 vans can be electrical. That led environmental teams and a coalition of states to sue the USPS.

The USPS gave into strain this summer time, and now plans for 50% of its preliminary procurement of the next-generation autos to be electrical, and when mixed with different varieties of autos within the fleet, 40% will probably be electrical.

U-M researchers appeared on the authentic plan of 10% EVs, evaluating it to an all-electric fleet. They discovered that greenhouse gasoline emissions underneath the ten%-EV state of affairs can be 15% increased 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 vans. The USPS examine appeared to imagine the grid will not get any cleaner than the current—however in fact it nearly definitely will.

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

These findings counsel the USPS ought to be electrifying at a fee a lot increased than even the raised 40% threshold, Greg Keoleian, senior creator of the examine, stated within the launch. The Inflation Discount Act, which leads to an in depth revamp of the EV tax credit score and, for a time, a limited number of eligible EVs, included one other $3 billion towards USPS electrical autos—so the second for a higher dedication is now.
