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.
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.
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. *Source: Umweltbundesamt
More confrontation with time pressure than with additional output
Selective perception of time pressure leads to ignoring consumption

Climate protection through reduced CO2 emissions
Awareness of own use is created
Reduction of environmental and health pollution due to further emissions (nitrogen oxides, carbon monoxide, particulate matter)
