Engine Technology Forum Defends Advanced Diesel and SCR Tech at EPA Hearing

The Engine Technology Forum brought its case for advanced diesel technology and selective catalytic reduction (SCR) systems to an EPA hearing, according to GlobeNewswire. The group used its testimony to argue that modern diesel engines and their emissions-control hardware deserve a place in ongoing regulatory discussions.

SCR systems are the aftertreatment setups that rely on a urea-based solution to cut nitrogen oxide emissions from diesel exhaust. By highlighting the technology at the hearing, the Forum signaled that continued refinement of diesel emissions controls — rather than an outright move away from the fuel — remains a priority for the industry.

The testimony lands as regulators weigh how to treat diesel within a broader shift toward electrified and lower-emission transport. The Forum’s position places advanced diesel and SCR hardware as part of the near-term emissions solution, a stance that will likely draw counterarguments from groups pushing for faster electrification.
