Fig. 4: Predicted choice share of mitigation options by individual characteristics.

Choice shares are calculated from logistic regression estimates, regressing mitigation option choice (yes/no) on income and climate concern among participants for whom the respective option was available, controlling for socio-demographic variables (see Supplementary Tables 15–29). Colors indicate mitigation option type (blue = Technology, red = Behavior, yellow = CO₂ certificates. Shapes indicate individual characteristic level: Points indicate low levels of income (i.e., < 6,000 CHF) and climate concern (i.e., not at all/not very/somewhat worried), triangles indicate high levels of income (i.e. > 12,000 CHF) and climate concern (i.e., very/extremely worried). Choice shares are calculated for low/high levels using a counterfactual approach: for each observation in the dataset, a key variable is set to high/low level, while all other covariates remain at their observed levels (n = 2,973). Error bars indicate 95% confidence intervals. Black bar outlines and error bars denote statistically significant effect of predictor on choice probability (α = 0.05).
