The impact of low-carbon consumption options on carbon footprints in the Nordic region

Abstract

Changes in personal consumption play an important role in the reduction of greenhouse gases (GHGs) to stay within the 1.5-degree warming carbon footprint budget. Affluent countries have high carbon footprints from a consumptive perspective and therefore have a high potential to reduce emissions from personal consumption. To study this potential, we look at the consumption-based carbon footprints of respondents from a carbon footprint calculator survey from the Nordic countries to compare the carbon footprints of those who participated in selected low-carbon consumption options to those that did not. The total sample size of the survey is 8,000 households. We analysed seven low-carbon consumption options within the domains of diet, transportation and housing energy. An input-output based hybrid assessment model was used to calculate the consumption-based carbon footprints. In addition to analysing these options separately, we also analysed them in combination. The lowest carbon footprints were associated with those respondents who did not own a car or had a vegan or vegetarian diet, and the largest difference in emissions was associated with not flying and not owning a car. Rebound effects for the consumption options were largely limited and were mostly not significant. Participation rates in the low-carbon consumption options were generally low. These results underscore the need for higher rates of adopting multiple low-carbon consumption options and can inform policy on which consumption options could be the most impactful.
