Plastic Bags and the Environment

Plastic bags are the most environmentally friendly option at the checkout. They’re 100% recyclable and highly reused. Studies show that alternatives which seem “greener” actually place a greater burden on the environment because they require more natural resources to produce and transport, they emit more carbon throughout their lifecycles and they need more energy to recycle – if they’re recyclable at all. On top of that, studies show bag bans and taxes haven’t meaningfully reduced overall litter or waste anywhere they’ve been tried.1

  • ENERGY SAVINGS: Plastic bags require 70% less energy to manufacture and consume 96% less water than what’s used to make paper bags.
  • DISPOSAL ADVANTAGES: Once disposed, reusable bags take up to 9.3% more space than plastic bags in landfills.
  • REUSABLE COTTON BAGS AREN’T REUSED ENOUGH: Standard reusable cotton grocery bags must be reused 131 times "to ensure that they have lower global warming potential than" a plastic bag used only once.2
  • NO OIL INVOLVED: American-made plastic bags are produced from byproducts of natural gas, not oil.3


The results are in: Bag bans and taxes don’t help to reduce waste, litter or marine debris.

Ban and tax ordinances have never been successful at meaningfully reducing litter, waste or marine debris. Not anywhere. What they have been shown to do is heap unfair costs on low- and fixed-income families and add more red tape to local businesses. The environment doesn’t benefit, and neither do people.

  • LANDFILL WASTE INCREASES: Plastic bags account for just half of 1% of U.S. waste, and without plastic grocery bags, people purchase replacement bags — often made of thicker, heavier plastic — and then send those bags to the landfill instead.4
    • In Austin, landfill waste increased after a bag ban because shoppers used and disposed of thicker plastic reusable bags in the place of standard plastic grocery bags.
  • LITTLE TO NO IMPACT ON OVERALL LITTER: Plastic retail bags comprise a very small portion of litter less than 2% – making bans and taxes ineffective when it comes to reducing overall litter.5
    • In Washington, D.C., a bag tax hasn’t improved litter or reduced bag use at all.6 According to a Washington Post investigation, D.C. collected roughly $10 million since 2010 without making any environmental progress. And the tax revenue keeps growing every year.7
    • A year after California implemented a statewide ban on plastic bags in 2016, an Ocean Conservancy survey showed a negligible 0.2% decrease in plastic bag litter as a percentage of overall litter.8

 

  • UNINTENDED CONSEQUENCES:
    • In Thurston County, Washington, a bag ban resulted in double the use of more resource-intensive paper bags.
