From Beaufort, South Carolina to Cape Cod, Massachusetts, and from Jefferson City to Providence, policymakers are pursuing a familiar approach: banning plastic bags while claiming environmental victory. However, this strategy rarely involves scrutinizing whether bans actually benefit the environment or whether they inadvertently create worse outcomes while preventing technologies that could genuinely address plastic pollution.
Scientific evidence undermines assumptions about plastic bag superiority. According to a Danish Environment Review, “a paper bag must be reused at least 43 times just to break even with the climate impact of a single plastic bag.” Research indicates paper bags generate significantly higher carbon footprints—over three times greater than single-use plastic alternatives—and produce substantially more solid waste.
The tradeoffs involved in bag bans receive insufficient attention. While paper bags may reduce littering impacts, they typically impose greater burdens on climate, eutrophication, and acidification compared to plastic alternatives. Policymakers emphasize visible beach pollution but ignore consequences like acid rain and forest clearing required for paper production.
Practical recycling concerns about plastic bags, while real, do not justify blanket prohibitions. Though plastic bags can jam sorting equipment at recycling facilities, the contamination challenge stems from insufficient consumer education and inadequate collection infrastructure—problems solvable through investment rather than elimination policies that shift difficulties upstream to paper manufacturers.
