Psychological factors influencing laypersons’ acceptance of climate engineering, climate change mitigation and business as usual scenarios

Publication Date Feb 1, 2020


Abstract In the past two decades, research on so-called climate engineering approaches has increased. These technologies are considered to be potential substitutes for mitigation strategies in combating climate change. The ongoing process of layperson acceptance and resultant opinion formation can be expected to play a crucial role in future public debate about field experiments or the actual deployment of climate engineering. In July 2017, we assessed public reactions from the German population in a representative online survey. Participants were given a brief text informing them about climate change and one of four different scenarios in a between-subject design (N = 678). Two of the scenarios described the use of climate engineering technologies - stratospheric aerosol injection (SAI) and bio-energy with carbon capture and storage (BECCS) - one of them covered conventional mitigation strategies and the fourth group was given an outline of the business-as-usual (BAU) approach. The mitigation scenario (willingness for individual behaviour changes) showed the highest acceptance rate (M = 74.23), which was significantly higher than acceptance of the other scenarios (p
