The construction sector is under a strong transformation, partly due to accelerating digitalization, and partly due to an increase in sustainability requirements. The drivers of digitalization are increased productivity, efficiency, and quality, whereas the requirements on sustainability performance are related to many external forces impacting the sector, such as stricter regulations on the verifiability of claims concerning resource efficiency, emissions, and waste management. In particular, the transport actors within the construction sector need a strategy to digitalize all their sustainability information. This report approaches this issue by integrating the BEAst (PEPPOL) standard for the construction sector’s data exchange with the ISO standard ISO 14033 for controlling the verifiability of quantitative sustainability information. The report shows how standards-based requirements on data exchange to and from all construction transport actors and stakeholders enable digitalization and data flows in a cost-efficient way and with short lead time to reduce administration, facilitate follow-up, enable traceability and verifiability, efficiency, and goal fulfillment combining societal and environmental benefits.
