Every day, individuals take decisions about their allocation of time to their activities, which mainly determines the environmental impact of their individual lifestyle. For example, a sales employee can decide whether to conduct a business trip in person or replace the physical trip with videoconferencing, a decision with immediate environmental impacts. Individual lifestyles are not only a major driver of environmental impacts, but are also affected by ICT applications which modify the time and space constraints of various activities (e.g., telecommuting allows to work from home instead of the employer’s office). We propose a new assessment approach based on the relationship between ICT use, time use patterns, infrastructure utilization and environmental impact.
We demonstrate the approach by showing how time-use data can be analyzed and linked with data on the energy requirements of activities to assess the energy impacts of a change in time allocation using the example use case telecommuting. Telecommuting means substituting physical presence in the employer’s office with virtual presence and remote access to data, e.g. by working from home or from a local co-working space and thereby reducing commute time and the related energy consumption. Telecommuting is subject to time rebound effects. That is, reducing commuting allows telecommuters to spend the commute time saved on travel for other purposes and non-travel activities such as leisure, which are associated with their own energy requirements.
We apply the time-use approach using time-use and travel data collected in an actual co-working living laboratory in Stockholm, Sweden.
