ECO SWISS was established in 1997 as a successor to the 'Association for the Promotion of Water and Air Hygiene', which was founded in 1969.

The association was created to promote corporate environmental protection and has since been actively involved in shaping federal environmental legislation by providing statements during consultations.

The inspectorate with exhaust air measurements has been one of the services offered since the beginning. Activities of the inspectorate in the field of corrosion protection as well as waste water control were given up by 1997 at the latest. The last conference with lectures and supplier exhibition was also held in 1997 at the former HTI Brugg-Windisch, by the way, the topic at that time was «The use of combined heat and power and heat pumps in industry».

The FCOS industry solution «Occupational health and safety in chemical-processing SMEs and biotech companies» has existed with its current orientation since 2004.

In 2007, the «Large Tank Farm» department was added.
