In France, The "Autorité de la Concurrence" -ADLC (French Competition Authority) may deliver opinions. An association of importers of petroleum products asked it his opinion on statistics of sales made by each warehouse of petroleum products on each area of the national territory, published monthly. By notice on May 15, 2012, the Authority replied that such statistics on each operator are welcome because they generate transparency on the retail market, although it should be that statistics cover all of the territory and are published every six months or annually.
