Promoting Pro-environmental Beliefs and Behaviour: Choose-Your-Own Story Futuristic Climate Game

PLOS ONE | https://doi.org/10.1371/journal.pone.0317773 March 31, 2025 12 / 18 PLOS ONE Promoting Pro-environmental Beliefs and Behaviour Like in the UK study, the results of the OLS regression analyses that examine the H1a, b, and c show that the climate game has no main effect on subjects’ beliefs that “world’s cli- mate is changing”, that “climate change is mainly caused by humans”, that “climate change will harm future generations”, or that “climate change will harm respondents personally”. The main effects of climate game on support for pro-environmental policies, and climate action, including people’s willingness to sign a climate petition are similarly null (see Table 4). Fig 7.
