Washington, DC, April 07, 2026 (GLOBE NEWSWIRE) -- Selective Catalytic Reduction (SCR) systems and the use of diesel exhaust fluid (DEF) have drawn renewed attention across the agricultural, trucking, and equipment sectors following recent actions and guidance from the U.S. Environmental Protection Agency (EPA).
To help stakeholders better understand these advanced emissions control technologies and the evolving regulatory landscape, the Engine Technology Forum (ETF) will host a webinar on Monday, April 20, from 2:00 to 3:00 p.m. ET.
The webinar will feature technical experts in SCR systems, DEF industry leaders, and policy specialists who will explain how SCR technology reduces emissions, the critical role of DEF, and how manufacturers and users are responding to recent EPA guidance. Speakers will also discuss policy developments, market trends, and the future of advanced diesel engine technology.
“For more than a decade, modern diesel engines have delivered near‑zero emissions and improved fuel efficiency – since 2010 for highway vehicles and since 2014 for most off‑road engines and equipment,” said Allen Schaeffer, Executive Director of the Engine Technology Forum. “SCR systems and DEF are central to these achievements. This session will be valuable both for those with long experience using these technologies and for those just getting started. We’ll address how industry is implementing new EPA guidance while continuing its commitment to customers and cleaner air.”
The webinar will cover:
- How SCR systems work and their role in today’s advanced diesel engines, including the importance, supply, and production of DEF
- Why SCR systems are used and the benefits they deliver in emissions reduction and fuel efficiency
- Recent EPA guidance on SCR and DEF systems and how manufacturers are responding and implementing the guidance
Featured panelists:
- Dr. Louise Arnold, New Business Development & Regulatory Affairs (US), Johnson Matthey
- Alan Smith, Senior Director Focus Industries, Brenntag North America LLC
- Allen Schaeffer, Executive Director, Engine Technology Forum
The webinar is free to attend, but advance registration is required.
