The Minnesota Pollution Control Agency recently featured Spectro Alloys' emissions reductions from replacing diesel forklifts with more efficient units. Here's a summary of the benefits from the MPCA website (link above):
They replaced a pair of old diesel forklifts (a Tier-0 and a Tier-1) that essentially had no emission controls. A DERA grant helped them purchase two new forklifts that meet the latest emissions standards (Tier-4), cutting fine-particle pollution by 99 percent. That is nearly one ton of pollution, the equivalent of cutting the annual pollution of 19,000 average cars. Big reductions are also seen in nitrogen oxides (58%), hydrocarbons (87%) and carbon monoxide (97%).
In addition to the two units replaced as part of this grant program, we replaced 6 other diesel forklifts with electric forklifts in 2017. From an operational and environmental standpoint it was a win/win!
