Climate policy - nudging instead of legal speed limit
To raise awareness of potential savings, signs are placed on cleared stretches of highway. These feature concise statements that show people how much more CO2 is emitted by driving faster.
What does the topic mean?
Apart from the Isle of Man, Germany is the only country in Europe without a general statutory speed limit on freeways. Yet a generalized speed limit has been part of the political and social discourse in Germany for around 40 years. Especially now, against the backdrop of the climate crisis, the debate is once again topical.
Goal of the nudge
With our nudge, we want to reduce the greenhouse gases emitted in the transport sector in Germany. A speed limit of 100 km/h could save up to 5.4 million tons of CO2 equivalents per year. * Currently it is not yet foreseeable if and when the speed limit will be introduced in Germany, therefore our approach: Nudging instead of a legal speed limit.

Needs Analysis
Greenhouse gases are the cause of the climate crisis
Transport sector third largest polluter
Climate protection goal 2030
To meet the targets set, greenhouse gas emissions from transport would have to be reduced to 85 million metric tons of CO2
Lack of information
Exact effects of one's own driving behavior are misjudged
Cause Analysis
Misestimation of time savings and additional CO2 emissions
Representation heuristic
More confrontation with time pressure than with additional output
Attention error
Selective perception of time pressure leads to ignoring consumption
Target Group
People who travel distances on the highway in passenger cars with internal combustion engines.
Added value of the nudge
Added value 1
Climate protection through reduced CO2 emissions
Added value 2
Awareness of own use is created
Added value 3
Reduction of environmental and health pollution due to further emissions (nitrogen oxides, carbon monoxide, particulate matter)
