Which choices contribute most to climate change? Most people miss the mark, one study found

  • A recent National Academy of Sciences study found many Americans misjudge how personal choices contribute to climate change.
  • Experts attribute this misjudgment to marketing emphasis on low-impact actions like recycling rather than high-impact behaviors such as flying or eating meat.
  • The study highlights that skipping a round-trip flight, which emits over 1,300 pounds of CO2 per passenger, matches or exceeds carbon savings from avoiding meat or living car-free for months.
  • Madalina Vlasceanu said people “over-assign impact to low-impact actions” like recycling and underestimate flying’s carbon footprint, while Brenda Ekwurzel noted deliberate confusion supports outdated policies.
  • The findings suggest improving public access to clear information could better align behavior with impactful climate actions and policy reforms.
