The plastic tax would have to be insanely high to be effective. The story of California’s plastic bag tax is a cautionary tale. Taxing the bag minimally was ineffective since everyone just paid the extra $2 a grocery trip for the disposable bags. California then tried an outright ban, but had to limit the ban because a large volume of pre-packaged items are already in plastic bags. The limit was based on bag thickness, so all the stores started handing out thicker bags at checkout. Despite the increased durability of the thicker bags, consumers discarded them at the same rate as the old thinner bags. Since each bag was made of more plastic there was more plastic waste than before the tax and ban.
