As the energy performance of the existing and new built building stock keeps improving and with carbon neutral power, electrification and zero emission fuels being phased in the climate impact of the construction process becomes increasingly important. Previous studies have shown that the total climate impact of building construction processes in Sweden is around 4 MtCO2-eq. Thus, a move towards zero emission in the constructions industry will require a complete overhaul of the way building materials are produced, supplied and used.

The aim of this study is to provide concrete examples of how innovative technologies, business models and innovation support mechanisms can accelerate the transition towards zero-emission practices in the construction and building materials industries. The focus will be on the production and use of basic materials from raw materials, over primary and secondary activities, to final products and services.

The case study will consist of the following main steps:

• Mapping of existing overall energy, material and value flows and development of tools to assess key factors with the potential to impact these flows.

• A review and assessment of existing and possible upcoming policy requirement targeting the construction and building materials industry.

Expected results:

• A description of the key energy, material and value flows relevant for the climate impact of the construction of buildings

• Concrete examples of how industries for the production of basic materials and the various actors involved in the supply chain from raw materials to completed buildings can work together to develop new practices and create new market opportunities in the transformation process towards zero emissions construction.

• Suggestions of how procurement-related policies should be designed to enable and support the development towards low carbon production of basic materials.
