Australian voters’ attitudes to climate action and their social-political determinants

for Australia reducing greenhouse gases (Fig 2). These variables were (factors predicting higher support in parentheses): political party preference (Greens & Labor p < 0.0001), educational attainment (more education p = 0.0012), and gender (women p < 0.0001). Age is also highly significant (younger p < 0.0001 in univariate analysis), as is the preva- lence of socioeconomic disadvantage in the local area where respondents live (less Fig 1. Distribution (by percent of all voters for each of the major political parties) of opinion about the importance of Australia reducing greenhouse gas emissions. https://doi.org/10.1371/journal.pone.0248268.g001 Fig 2. Forest plots illustrating odds ratios and 95% confidence interval of the odds ratio for Q1: “In your view, how important or unimportant is it that Australia takes action to reduce greenhouse gas emissions in order to help limit future climate change?” Left panels are univariate analyses; right panels are multivariate analyses; upper panels are continuous independent variables; lower panels are categorical independent variables. For continuous independent variables, the variables have been modified where necessary so that the OR is measuring more quantity of the variable listed on the y axis (i.e., more income, more education, more disadvantage in the area of residence, more age). For categorical variables, comparisons are to the default baseline category only (baseline category not displayed in plots: Liberal; Male; NSW; Capital city; English speaking background; Language (English)). Variables that are

statistically significant at (α = 0.05) do not cross the OR value of 1, indicated by dashed vertical line, with their 95% confidence interval. Note the differing scales on the x-axes across plots. https://doi.org/10.1371/journal.pone.0248268.g002 PLOS ONE Australian voters’ attitudes to climate action and their social-political determinants PLOS ONE | https://doi.org/10.1371/journal.pone.0248268 March 24, 2021 6 / 18
