The European Union (EU) has targeted the adoption of environmentally-friendly public transportation (EFPT) system as a strategic initiative to improve local ambient air quality, reduce road congestion, and contribute to the reduction of greenhouse gas (GHG) emissions. In support of these policy goals, this study assesses and compares public support for EFPT across 31 European nations. We use a Bayesian logit model with identified scale to estimate the willingness to pay (WTP) for local EFPT upgrades, utilizing data from 6,520 contingent valuation survey responses. Our findings indicate that WTP is primarily driven by expected improvements in public goods, such as air quality and GHG abatement, rather than private ridership benefits. On average, individuals across all nations demonstrate a WTP of € 7.48 per month. The consistently positive WTP distributions across all nations suggest implicit public support for EFPT at the EU-level.
