The aim of the campaign is to raise public awareness of the new EU Registration, Evaluation and Authorisation of Chemicals (REACH) policy being debated in the European Parliament. Lush believes the legislation could undermine the existing European Cosmetics Directive and lead to a re-introduction of animal testing for cosmetic ingredients.
From July 17, the beauty retailer will be dressing every window in its European stores with a Vote here against animal testing display.
One-off voting days, which will use polling booths, will also be held at the retailer's flagship stores.
Lush will deliver all the votes it collects to relevant government bodies and MEPs.
Animal rights campaigner Andrew Butler, who used to work for PETA, has been appointed campaign manager.
