Measuring Plastic Bag Laws Effectiveness
Are the laws working?
This comprehensive spreadsheet of effectiveness data (embedded below) was prepared by Scientist Action and Advocacy Network (ScAAN) in partnership with PlasticBagLaws.org. Please email info[at]plasticbaglaws.org if you know of other effectiveness studies that should be added to the Effectiveness Spreadsheet.
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 this protocol. Having a consistent collection methodology will ensure 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.
