    • We examined public WTP and the determinants for CO2 mitigation in Suzhou, China.
    • Trust crisis and people's low responsibility are the leading causes of zero-bid.
    • Increasing income and education will increase people's WTP.
    • Lower dread, longer duration and greater influence of GHG risk will increase WTP.
    • High confidence in policy and timely information disclosure will increase WTP.


    This study explored the factors that influence respondents' willingness to pay (WTP) for CO2 mitigation under climate change. A questionnaire survey combined with contingent valuation and psychometric paradigm methods were conducted in the city of Suzhou, Jiangsu Province in China. Respondents' traditional demographic attributes, risk perception of greenhouse gas (GHG), and attitude toward the government's risk management practices were established using a Tobit model to analyze the determinants. The results showed that about 55% of the respondents refused to pay for CO2 mitigation, respondent's WTP increased with increasing CO2 mitigation percentage. Important factors influencing WTP include people's feeling of dread of GHGs, confidence in policy, the timeliness of governmental information disclosure, age, education and income level.
