  • Increase energy efficiency
    Run chemical reactions at room temperature and pressure whenever possible
  • Maximize atom economy
    Design syntheses so that the final product contains the maximum proportion of the starting materials. Waste few or no atoms.
  • Analyse in real-time to prevent pollution
    Include in-process monitoring to minimise or eliminate the formation of byproducts
  • Use renewable feedstocks
    Use starting materials {also known as feedstocks) that are renewable rather than depletable.
  • Minimise the potential for accidents
    choose the materials for the process which are non-explosive or non-flammable wherever it is possible
  • Prevent waste
    Design chemical syntheses to prevent waste. Leave no waste to treat or clean up.
  • Avoid chemical derivatives
    Minimize the production of unnecessary compounds. Derivatives use additional reagents and generate waste.
  • Design safer chemicals and products
    Design chemical products that are fully effective yet have little or no toxicity.
  • Design less hazardous chemical syntheses
    Design syntheses to use and generate substances with little or no toxicity to either humans or the environment.
  • Use catalysts, not stoichiometric reagents
    Use catalysts which are effective in small amounts and can carry out a single reaction many times. Don't use stoichiometric reagents which react only once.
  • Use safer solvents and reaction conditions
    Avoid using solvents, separation agents or other auxiliary chemicals. If you must use these chemicals, use safer ones.
  • Design chemicals and products to degrade afte use
    Design products that break down to innocuous substances after use
