Comparing Apples and Pears. An experimental study of how awareness about climate change and ocean acidification affect people's propensity to support an increase of the Swedish CO2-tax
In numerous studies (mainly survey studies) a correlation between environmental knowledge/awareness and pro-environmental behaviour/ acceptance of policy measures has been demonstrated. The climate change problem is well researched in this regard. Thus, it is typically argued that climate change awareness lead to more positive attitudes towards policies such as a CO2-tax. However, 1) far less is known about the relationship between awareness of ocean acidification and willingness to support/accept a CO2-tax aimed at mitigating CO2-emissions (contributing to OA), 2) even less is known about potential reinforcing effects if people are aware of both CC and OA (highly related problems since CO2-emissions are stressing them both) and 3) since mainly survey studies are being used in this research, we know basically nothing about the causality.
