The 12 Principles of Green Chemistry

Core guidelines established by Paul Anastas and John Warner that define sustainable chemical practice and innovation.

1

Prevent Waste

Design chemical syntheses to prevent waste, leaving no waste to treat or clean up.

2

Atom Economy

Design syntheses so that the final product contains the maximum proportion of the starting materials.

3

Less Hazardous Synthesis

Design syntheses to use and generate substances with little or no toxicity to humans and the environment.

4

Safer Chemicals

Design chemical products to be fully effective yet have minimal toxicity.

5

Safer Solvents

Avoid using solvents, separation agents, or other auxiliary chemicals when possible.

6

Energy Efficiency

Minimize energy requirements and conduct reactions at ambient temperature and pressure.

7

Renewable Feedstocks

Use raw materials from renewable sources rather than depleting fossil fuels.

8

Reduce Derivatives

Minimize or avoid chemical derivatizations which require additional reagents and generate waste.

9

Catalysis

Use catalytic reagents in preference to stoichiometric reagents for greater efficiency.

10

Design for Degradation

Design products to break down into innocuous substances after use to prevent environmental accumulation.

11

Real-Time Analysis

Develop analytical methodologies for real-time monitoring to prevent formation of hazardous substances.

12

Accident Prevention

Choose substances and their forms to minimize potential for accidents including explosions and fires.
