In an On Physical Sciences blog, Sandra Venghaus and Katharina Böhm describe how their study explored the extent to which increasing climate change awareness actually bridges the attitude−behavior gap in Germany.
supportive opinions towards topics related to climate change and sustainability in general do not automatically lead to sustainable behavior
However, even if there are clear indications that climate change awareness and the willingness to mitigate global warming is rising within the population, the so-called attitude−behavior gap is often observed: supportive opinions towards topics related to climate change and sustainability in general do not automatically lead to sustainable behavior.
We therefore explored the case study of Germany to determine the extent to which increasing climate change awareness actually bridges the attitude−behavior gap in the three sectors that account for over 80% of total German greenhouse gas emissions: mobility, food consumption, and housing. On the other hand, in 2019, a trend towards the usage of larger and more uneconomic vehicles was observed, according to the Federal Motor Transport Authority .
Food consumption Food consumption accounts for roughly 30% of German household GHG emissions. In 2019, pork consumption decreased, while the volume of organic food sales increased.The increased consumption of organic food has been found to originate from the prevalence of environmental topics in the media and the consequences of the Fridays for Future movement.
