Do non-ionizing radiation concerns affect people's choice between hybrid and traditional cars?

Abstract

Overview

The rapidly expanding market for hybrid electric vehicles (HEVs) has led to increased concerns about long-term exposure to non-ionizing radiation (NIR). This study examines how concerns over electromagnetic fields and NIR specifically influence consumers' choices between HEVs and traditional internal combustion engine (ICE) vehicles.

Findings

• Exposure to information about NIR is associated with a lower probability of selecting HEVs compared to ICE vehicles.
• Individuals who experience "NIR-dread" are more likely to prefer ICE vehicles, while those skeptical about NIR risks are likelier to choose HEVs.
• Both positively and negatively framed information about NIR discourages the choice of HEVs compared to providing no information.
• The stated choice experiment data, analyzed using a hybrid choice model, highlight the impact of both health risk perceptions and environmental attitudes in shaping consumer decisions.

Conclusion and Policy Recommendations

• The absence of clear regulatory frameworks could result in the production of electric vehicles with inadequate NIR safety standards, signaling the importance of establishing international safety guidelines for NIR emitted by vehicles.
• Perceptions of NIR risk—both dread and skepticism—influence consumers. Disseminating scientific evidence on the short- and long-term effects of NIR exposure is necessary to inform public decision-making and mitigate unfounded fears.
• The quality of information about NIR safety strongly affects consumer choice. Both positive and negative presentations of safety thresholds can deter consumers, indicating the need for transparent, standardized communication.
• Traveling with children is negatively associated with HEV leasing, possibly due to broader reliability or health concerns. Prior studies highlight parental concern for children's exposure to NIR from other sources (e.g., mobile phones), supporting the need for further research on how EMF health risks affect family vehicle choice.

Overall, the study finds a clear connection between NIR/EMF health risk awareness and consumer preferences in vehicle choice, emphasizing that EMF safety is a crucial factor for both policymakers and the public as electric vehicle adoption increases.
