VERT is a Nonprofit Association of filter, catalyst, instrument, and engine manufacturers, universities, and research associates.
The VERT® Association, founded in Switzerland in 1993, originated during the New Transalpine Railways Program. Since then, VERT® has developed some of the most important particle filter testing procedures, supported international partners with retrofit programs, and established a worldwide scientific network of manufacturers of systems, engines, vehicles, and PN measurement devices, as well as environmental, medical, and technical research facilities specialized in Air Quality and nanoparticle emissions control.
VERT organizes the international VERT Forum and ETH Nanoparticle Conference every year.
