The VERT Association is a Swiss-based non-profit organization focused on enabling use of best available technology (BAT) for combustion engine exhaust emissions control in retrofit and original equipment as well as to assure best retrofit practices.

The association runs the VERT Filter List, an international standard for validating emissions testing particle filters.

The association is closely associated with Technik Thermische Maschinen (TMM) and the University of Bern’s IC Engine and Emissions Control Laboratory (AFHB).
