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.
