What are the global policy reviews?
To understand what makes plastic policy effective, 100 different policies that addressed plastic were identified. These policies included:
Legally binding policies
- bans on plastic bags
- bans on single use plastic products (SUPPs)
- taxes on plastic products
- recycling regulations
- extended producer accountability
- industry commitments
- affirmative action
- information instruments
- plastic pacts
These policies were then reviewed against a set of criteria to establish what made them effective or ineffective. For more information see our Methods page.
