Predictors of Willingness to Reduce Carbon Footprint and Effects of Survey Question Phrasing

Abstract

To minimize and prevent the many negative effects associated with climate change people must reduce their carbon footprints. Our objectives were to determine whether a person’s likelihood to take political action against climate change, perceptions about fracking, and education level affect their willingness to reduce carbon footprint, and whether phrasing of a survey question affects how people respond. To this end, participants’ responses were used from the publicly available nationally representative 2015 Cornell National Social Survey (CNSS) of 1,000 United States adults. Statistical analysis involved estimation and comparison of odds ratios (ORs) and the associated 95% confidence intervals (95% CIs). Findings indicated that willingness to reduce carbon footprint was positively associated with being likely to take political action against climate change (OR=6.53, 95% CI: 4.63-9.20) and with having gone to college (OR=1.43, 95% CI: 1.06-1.94). Conversely, support for fracking had a negative association with willingness to reduce carbon footprint (OR=0.42, 95% CI: 0.31-0.56). In CNSS, the question about carbon footprint was phrased in five different ways that either mentioned the danger from climate change or the benefit from reducing climate change, and linked the benefit or danger to humans or birds. It was discovered that how the question is asked matters. Participants appeared more affected by mention of humans than animals, though reactions to benefit and danger were not consistent. These findings will aid education efforts about climate change and carbon footprint and also help in the design of future surveys on the topic.
