Abstract
Existing research comparing regulatory processes for environmental and health hazards in Europe and North America indicates that there are considerable differences in the ways that countries with quite similar legal and political traditions approach both the scientific evidence on which policy is made and the frameworks that are used to implement such policy. Such differences may be even more extreme between countries with vastly different cultures and political traditions. This article describes and accounts for such differences in political, legislative, administrative, regulatory, and judicial systems that may present obstacles to reaching international accord.
