Abstract:

In response to concerns of climate change, individuals are often provided with information on greenhouse gas emissions (GHGs) whether for trips or for purchases such as personal vehicles. Currently in the US, information on vehicle efficiency is provided as grams of carbon dioxide (CO₂) per mile. Previous research has found benefits of providing this information on vehicle choice, but other research has also questioned whether how this information is presented might affect choice. That latter research argues that CO₂ emission information generally lacks contextualization that allows for interpretation. As well, the type of contextualization may affect choices. Research exists that argues that using pro-social, as opposed to financial, contextualization might be more influential. This research will attempt to combine these approaches and determine whether changing how CO₂ information is presented will have a significant impact on vehicle choice through a willingness-to-pay choice experiment using latent class modeling. Five different methods of presenting the information are tested in this experiment: CO₂ emissions as grams per mile (current method), CO₂ emissions as pounds per year (consistent imperial units), CO₂ emissions as tons per year (yearly contextualization), an annual tax on CO₂ (yearly financial contextualization), and CO₂ as a percentage of the 2025 US EPA reduction target of 26% from 2005 levels (social goal contextualization). Results demonstrate that the current method results in lowest willingness to pay for CO₂ emission reductions, while social goals result in the highest.
