Aims & Scope

This journal publishes papers that aid in the development, demonstration, and commercialization of cleaner products and processes as well as effective environmental policy strategies. As its title suggests, the journal has two major thrusts: Clean Technologies and Environmental Policy. The Clean Technology thrust addresses the science and engineering of clean technologies. Moreover, it examines mathematical and computer-based methods and models for designing, analyzing, and measuring the cleanliness of products and processes. The Environmental Policy thrust covers research advances in scientific, social, behavioral, and economics disciplines that are relevant to complex environmental policy issues. In addition to research papers, the journal offers policy-oriented commentaries from world renowned leaders in environmental technology and policy research. It also features special issues focusing on topics of international concern.
