Are plastic bag laws effective? The good news is there are plastic bag laws being adopted throughout the U.S. with the intention of curbing the use of single-use plastic bags. However, how effective these laws are can vary.
With this in mind, PlasticBagLaws.org partnered with Scientist Action and Advocacy Network (ScAAN) to develop a comprehensive spreadsheet of plastic bag law effectiveness data. ScAAN’s members are doctoral students, PhD-holding research scientists, and professors who donate their skilled labor and expertise to our partner organizations. ScAAN’s members volunteer pro bono to compile brief, targeted literature reviews, and analyze pre-existing data.
The Effectiveness Spreadsheet is linked to in Surfrider Foundation’s Plastic Bag Law Activist Toolkit and the toolkit features summaries of the findings from U.S. studies currently available. Examples of summaries from the spreadsheet:
A key takeaway from the studies summarized is that Fees on All Bags and Ban/Fee Hybrids laws are effective at reducing overall carryout bag consumption through changing consumer behavior.
“All studies show that after a Ban/Fee Hybrid was implemented, many more people started bringing reusable bags—and the number of people who chose not to use a bag at all at the register increased dramatically in places like Richmond, CA, Santa Monica, CA, and Chicago, IL,” said Jenn Laura Lee, President of ScAAN. “In Washington, DC, residents reported seeing fewer bags around the neighborhood.”
