It's a basic question faced by millions of shoppers every day: paper or plastic? Making the best choice for the environment, however, is less simple.
Last November, Californians approved Proposition 67, which upheld a 2014 ban on the issuing of single-use plastic bags in grocery and drug stores. As a result, shops were able to continue charging customers around a dime for reusable plastic or paper bags. The ban seems effective because it should lead to a reduction in plastic waste. More importantly, the extra charge aims to incentivize people to bring their own reusable bags to the store. But let's face it, many shoppers still forget, which brings us back to that darn choice we often have to make at the checkout line.
So, which option is better?
[...]The U.K. Environment Agency, a governmental research group, conducted a similar inquiry around the same time period. Its report[PDF] was a life cycle assessment comparing the environmental impacts of a variety of grocery bags. From extensive research, some of the study's key findings concluded that:
- Single-use plastic bags outperformed all alternatives, even reusable ones, on environmental performance.
- Plastic bags have a much lower global warming potential.
- The environmental impact of all types of bag is dominated by the resource use and production stages. Transport, secondary packaging, and end-of-life management generally have minimal influence on their performance.
- Whatever type of bag is used, the key to reducing the impacts is to reuse it as many times as possible.
The ecological break-even point with a cloth grocery bag comes on its 131st use.
