Models shape our understanding of reality and thus provide the basis for our actions. The modern world can no longer be understood through personal experience alone, so models are needed that can be communicated and experienced through media. Wide availability and functionality make information and communication technology (ICT) an important instrument for combating climate change.

Models and data can make the effects of action tangible and options for action visible through digital artefacts. In this way, cultural and institutionalised practices can be questioned and ideally changed. Artefacts have an effect in the dimensions of immediacy, awareness, intentionality, degree of human influence and direction of the result.

Additional challenges here are the rebound effect (CO2 savings are more than compensated by additional expenditures) and the psychological climate paradox (the level of information about the climate consequences of one's own actions does not lead to CO2 reductions). The following areas define the framework of activities:

• Raising awareness of the impacts of forms of mobility
• Identifying sustainable alternatives
• Conception and development of innovative mobility services with a high sustainability factor
• Consideration of a holistic sustainability approach (social, economic and ecological)
• Consideration of diverse preconditions of different lifestyles and a changing society
