A study by the National Academy of Sciences in 2025 found that many people in the United States have the wrong idea about which personal actions help most in fighting climate change. The research asked participants to rank activities such as switching to electric cars, carpooling, and reducing food waste. Results showed that people gave excessive attention to small but visible habits like recycling, while ignoring high-impact actions such as avoiding flights, not owning a dog, and using renewable energy. Experts explained that climate change is mainly caused by greenhouse gases from burning fossil fuels, and the most pivotal actions lower these emissions.

Researchers said marketing often emphasizes visible habits, making them seem more important. Psychologists stated that recycling feels easier to remember than invisible emissions from flights. Air travel releases large amounts of carbon dioxide, and dog ownership raises emissions due to pet food production. Renewable energy from solar and wind can greatly cut emissions. Better public awareness can lead to more intentional and constructive climate-friendly actions.
