Many Finnish cities have launched their own political sustainability programs with ambitious targets to reach carbon neutrality within a couple of decades. In order to achieve this also infrastructure investments should be analyzed and chosen according to their carbon footprint and other sustainability values.

There are various apps that enable either building projects cost or carbon accounting. However, these apps do not communicate with each other or with the building information model (BIM).  At the project level, the accounting is made separately. Cost-accounting itself is today a smooth practice in infrastructure projects. There is also the first software launched for house building projects which combine cost and carbon accounting. In addition to carbon footprint calculations, there are other sustainability aspects that should be taken into account within the political decision-making process. There are biodiversity estimations, planetary boundaries model, no net loss calculation (ecological compensation)  model, and various other perspectives.

However, having separate cost, carbon, and sustainability information for individual projects does not help our political decision-makers to get the bigger picture of the problems.

We challenge the participants to choose this challenge and to help produce better cost – carbon – sustainability information for the infrastructure projects and for the political decision-making process. The information can be attached to a BIM model, an infographic, a calculation model, etc.

We provide the participants with cost calculation data (excel form) and a BIM model.  There are open databases for carbon calculations (SYKEs carbon footprint calculators). Biodiversity assessment tools are available from open-source (Ecosystems Knowledge Networks tools). Unfortunately, there are no open databases for other sustainability aspects, but we challenge you to tell us, how these various aspects should be included in the information.

We hope the challenge inspires participants to find out a solution towards integrated decision making.
