Résumé
REACH legislation stands apart from other environmental and health legislations in two major respects. First, it enshrines a legal principle of reversal of burden of proof by making firms responsible for demonstrating the harmlessness of the products they use. Second, it requires firms to disclose all the toxicological and environmental information at their disposal on the substances they use. This article looks at the impact of information-sharing arrangements and the influence of REACH legislation on competition and innovation.
