- Dependent on context
- Hard to craft to avoid loopholes
- Costly to enforce
Would that be taxing pollution at production? Perhaps. With external audits (other businesses auditing each other may be more sustainable than a singular auditing agency).
Harder to do for global markets. Only way to do some regulation is to tax upon exportation.
Does that include sustainable waste management? Recycling, re-usability.
