The City of San Jose, to their credit, is one of the few cities that conducted litter surveys both before and after the city’s bag ban. Results showing the percentage reduction of single-use plastic carryout bags (i.e. plastic grocery bags) as a component of litter have been cited by the city as proof that the city’s bag ban is effective. Likewise, environmental groups nationwide have touted these same results as a justification for promoting new bag bans and opposing repeal efforts. Unfortunately, the City of San Jose did not conduct litter surveys in a controlled and scientific manner, did not correctly analyze survey data, and did not put survey results into proper perspective. As a result, the data collected is unreliable for computing a meaningful figure of merit, such as the percent reduction in plastic carryout bag litter resulting from the city’s plastic bag ban.

Yet, despite these shortcomings, the litter surveys did reveal several surprising facts that have escaped the notice of city officials, the media, and those in other cities who cite San Jose’s claims:

  • That only half of ALL plastic bag litter found in sampled areas on city streets and creeks consists of single-use plastic carryout bags; hence, a bag ban would at most eliminate only about half of all plastic bag litter.
  • That only about 10% of litter in creeks consists of single-use plastic carryout bags; hence, a bag ban affects at most 10% of ALL litter in creeks, leaving the remaining 90% unresolved. Therefore, all of the cost and cleanup efforts still need to be implemented since this will not meet the 100% reduction goal required under the federal Clean Water Act.
  • That the number of single-use plastic carryout bags found during all of the litter surveys in 2009, 2010, and 2011 (prior to the bag ban) average only 1,000 bags per year, or less than 1 for every 1,000 people, or the equivalent of what two (2) people out of a population of more than 1 million would use annually!

The use of unreliable and questionable survey data to project large percentage reductions of an insignificant number of littered plastic grocery bags combined with a complete lack of evidence of any cost savings to the city or to the people show that the bag ban was never justified from the beginning, and that the ongoing cost burden to San Jose families is likewise unjustified.
