In 1994 the cooperative obtained the franchise for the Gamm Vert brand becoming the first franchisee in the French overseas territories network.

Set up in 1977, Gamm Vert is a subsidiary of the group INVIVO (the 1st European agricultural sales, purchasing and service cooperative). The brand is a market leader in the area of "green" distribution and has over 700 stores throughout France, Luxembourg and in Poland.

25% of customers are members of the cooperative and benefit from particular special offers.

Gamm Vert represents more than 43% of the turnover of the Coopérative des Avirons: 17 million euros in 2004/2005.
