2. Atom Economy

3. Less Hazardous Chemical Syntheses

4. Designing Safer Chemicals

5. Safer Solvents and Auxiliaries

6. Design for Energy Efficiency

7. Use of Renewable Feedstock's

8. Reduce Derivatives

9. Catalysis (vs. Stoichiometric)

10. Design for Degradation

11. Real-time analysis for Pollution Prevention

12. Inherently Safer Chemistry for Accident Prevention
