Abstract:

There have been a considerable body of studies on the relationship between daily transport activities and CO₂ emissions. But, how these emissions vary across different weather conditions within and between seasons of the year are largely unknown. Since individual activity-travel patterns are not static but vary across different weather conditions, it is immensely important to understand how the CO₂ emissions vary due to the change of weather. Using Swedish National Travel Survey data, with emission factors calculated through European emission factor model ARTEMIS, this study is a first attempt to derive the amount of CO₂ emission changes subject to the change of weather conditions. A series of econometric models were used to model travel behaviour variables that are crucial for influencing individual CO₂ emissions. The marginal effects of weather variables on the travel behaviour variables were derived. The results show an increase of individual CO₂ emissions in warmer climate and in more extreme temperature conditions, while increasing precipitation amount and snow depth shows limited effects on individual CO₂ emissions. It is worth noting that the change of CO₂ emissions in the scenario of a warmer climate and a more extreme temperature tends to be larger than the sum of changes of CO₂ emissions in each single scenario. Given that warmer climate and more extreme weather would co-occur more frequently in future, this result suggests even larger individual CO₂ emissions in such a future climate than expected.
