12 Principles of Green Chemistry (Articles are invited based on these principles)

Developed by Paul Anastas and John Warner*, the following list outlines an early conception of what would make a greener chemical, process, or product.

  • Prevention
    It is better to prevent waste than to treat or clean up waste after it has been created.
  • Atom Economy
    Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product.
  • Less Hazardous Chemical Syntheses
    Wherever practicable, synthetic methods should be designed to use and generate substances that possess little or no toxicity to human health and the environment.
  • Designing Safer Chemicals
    Chemical products should be designed to affect their desired function while minimizing their toxicity.
  • Safer Solvents and Auxiliaries
    The use of auxiliary substances (e.g., solvents, separation agents, etc.) should be made unnecessary wherever possible and innocuous when used.
  • Design for Energy Efficiency
    Energy requirements of chemical processes should be recognized for their environmental and economic impacts and should be minimized. If possible, synthetic methods should be conducted at ambient temperature and pressure.
  • Use of Renewable Feedstocks
    A raw material or feedstock should be renewable rather than depleting whenever technically and economically practicable.
  • Reduce Derivatives
    Unnecessary derivatization (use of blocking groups, protection/ deprotection, temporary modification of physical/chemical processes) should be minimized or avoided if possible, because such steps require additional reagents and can generate waste.
  • Catalysis
    Catalytic reagents (as selective as possible) are superior to stoichiometric reagents.
  • Design for Degradation
    Chemical products should be designed so that at the end of their function they break down into innocuous degradation products and do not persist in the environment.
  • Real-time analysis for Pollution Prevention
    Analytical methodologies need to be further developed to allow for real-time, in-process monitoring and control prior to the formation of hazardous substances.
  • Inherently Safer Chemistry for Accident Prevention
    Substances and the form of a substance used in a chemical process should be chosen to minimize the potential for chemical accidents, including releases, explosions, and fires.
