Are the laws working?

This comprehensive spreadsheet of effectiveness data was prepared by Scientist Action and Advocacy Network (ScAAN) in partnership with

The Effectiveness Spreadsheet is linked in Surfrider Foundation’s Plastic Bag Law Activist Toolkit, and the toolkit features summaries of the findings from U.S. studies currently available.

Please email if you know of other effectiveness studies that should be added to the Effectiveness Spreadsheet.

Effectiveness Protocol

Collecting data on the effectiveness of local bag laws is very important in testing what laws and fees work in practice. The data can also be helpful when talking to legislators and the community. If you or your organization want to help in collecting data, follow the protocol linked here. Having a consistent collection methodology will ensure that data is useful and comparable later on.

We suggest partnering with a local University or non-profit group to assist in data collection and analysis.
