Twelve Principles of Green Chemistry

Meaning statusEstablishedSource recordDirect document linkedWhy these are different

Definition

The Twelve Principles of Green Chemistry, articulated by Paul Anastas and John Warner (1998), are the design framework for sustainable chemistry: prevent waste rather than treat it; maximise atom economy; design less hazardous syntheses; design safer chemicals; use safer solvents; increase energy efficiency; use renewable feedstocks; avoid derivatives; use catalysis; design for degradation; use real-time analysis for pollution prevention; and minimise accident potential. They are the field's constitution — adopted by the ACS Green Chemistry Institute and embedded in education and industry practice.
