Cummins’ Electrification Announcement is All Talk

Engine Manufacturer Remains Part of Trade Group Fighting Against Strong Truck Pollution Standards

Larisa Manescu,

WASHINGTON, DC – Cummins just announced a new electrification brand “Accelera” and a project with Blue Bird that plans to put 1,000 electric school buses on the road in the next 12 to 18 months.

Cummins is still a part of the Truck and Engine Manufacturers Association, a trade association that has fought for years to delay progress on the transition to electric trucks. The EMA urged the EPA to adopt weak federal NOx standards during the agency’s May 2022 public hearing, though it claims to support strong standards. 

The association has also been fighting in numerous states for years to block standards that will accelerate the adoption of electric trucks and buses. 

Ford recently left the EMA, and environment, health, and consumer advocacy organizations have been pressuring other members to ditch the organization

In response, Katherine García, Director of the Sierra Club’s Clean Transportation for All campaign, released the following statement:

“It’s great to see Cummins supporting the nation’s transition to electric school buses, which are better for our climate, our kids and bus drivers, and the health of our communities. But Cummins’ new brand announcement doesn’t make up for the company’s participation in the problematic Truck and Engine Manufacturers Association. If Cummins is serious about electrification it should step away from the industry group that has for years fought state and federal clean truck regulations.

“A true commitment to a pollution-free future is for all EMA members to follow Ford’s lead and withdraw from the trade group.”
