The  Presidential  Green
Chemistry  Challenge
Program  Scope  and  Objectives
        President Clinton announced the Presidential Green
        Chemistry {Challenge on March 16, 1995, as part of the
        Reinventing Environmental Regulations Initiative to "pro-
        mote pollution prevention and industrial ecology through a
        new EPA [U.S. Environmental Protection Agency] Design
        for the Environment partnership with the chemical indus-
        try." EPA's" Office of Pollution Prevention and Toxics is
        leading this;.voluntary partnership program with other EPA
        offices, otlifefederal agencies, members of the chemical
        industry, tKtde associations, scientific organizations, and
        academia. """'
        The Presidential Green Chemistry Challenge was estab-
        lished to recognize and promote fundamental and
        innovative chemical methodologies that accomplish pollu-
        tion prevention and that have broad application in industry.
        For purposes of the program, green chemistry is defined as
        the use of chemistry for source reduction, the highest tier of
        the risk management hierarchy as described in the Pollution
        Prevention Act of 1990. Green chemistry involves a reduc-
        tion in, or elimination of, the use or generation of '
        hazardous substances—including feedstocks, reagents, sol-
        vents, products, and byproducts—from a chemical process.
        Green chemistry encompasses all aspects and types of chem-
        ieal processes—including syndiesis, catalysis, analysis,
        monitoring, separations, and reaction conditions—that
        reduce negative impacts on human health and the environ-
        ment relative to the current state of the art.

              SCOPI  Focus AREAS
              The Presidential Green Chemistry Challenge recognizes and promotes the
              following green chemistry methodologies:

              L The use of alternative synthetic pathways for green chemistry, such as
                  • Catalysis/biocatalysis,
                  • Natural processes, such as photochemistry and biomimetic synthesis, or
                  • Alternative feedstocks that are more innocuous and renewable
 , "i                 (e-g-> biomass).
