VERT (Verification of Emission Reduction Technologies Association), legally known as VERT-Verein, is a non-profit organization founded in 1993 in Switzerland. Originally established as AKPF during the NEAT tunneling project, it promotes Best Available Technologies (BAT) for reducing emissions from internal combustion engines, with a primary focus on diesel particulate filters (DPF) and retrofit systems.
VERT develops rigorous testing protocols, certifies high-efficiency emission control technologies—such as DPFs achieving over 98% filtration of solid nanoparticles (20-300 nm)—and publishes the VERT Filter List as an international standard. Its procedures, harmonized with Swiss norm SN 277206, ensure durability after 2,000+ operating hours, low backpressure, no toxic secondary emissions, and reliability in real-world applications.
Pioneering nanoparticle measurement and DPF retrofitting, VERT has influenced global regulations, including mandatory DPF use in European tunneling, U.S. mining, and low-emission zones. Over 400,000 vehicles worldwide, including off-road machinery, feature VERT-certified systems. Members include engine makers, filter manufacturers, universities, and research institutes. VERT supports clean air initiatives, hosts annual forums, and advances retrofit programs for urban mobility and industrial sectors.
Also known as Verification of Emission Reduction Technologies Association and VERT-Association.
Electrically regenerating diesel particulate filter certified by CSA for Canadian underground mining/tunnelling; also certified by Canmet and VERT and approved by US MSHA.
