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

Voluntary policies

  • 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.
