Challenge

Construction accounts for around 30% of all CO2 emissions in Denmark, and in 2024 new building regulations demand full documentation of the total emission before construction work can be approved. B2B building materials merchant, STARK, has an ambition to take lead in reducing this impact by not only reducing the group’s own emissons, but also by sharing the CO2 emission numbers on all STARK’s products. This initiative is a response to the challenges faced by small- and midsized construction companies, who must comply with increasingly stringent climate and documentation requirements. In this way, craftspeople and entrepenors can choose, sell, and document more sustainable solutions. It serves as a true differentiator in a world where price is no longer the most crititical factor, but rather sustainability, transparency, and easy access to concrete climate numbers.

Approach

KlimaLog is a tool that provides professional builders with easy access to climate data and environmental labelling. The tool features a dashboard that offers a quick overview of the total carbon footprint, including the proportion of materials certified with STARK’s BygGrønt (“BuildGreen”) certificate. Additionally, users can download a PDF report for use in their climate accounting. More than 42,000 products enriched with Environmental Product Declaration data have been identified, read, and assessed using AI, resulting in one climate number for each product. Creating this data foundation has required a gigantic data transformation effort for STARK.

KlimaLog also offers a detailed overview of all one’s construction sites. This overview includes information on CO2 emissions, carbon footprint, and the presence of “BuildGreen” certificates for all materials in use. By filtering on material and certifications, users can identify products with a high climate or specific labelling. These numbers are crucial for the Life Cycle Assessment (LCA) and assist in making more sustainable material choices.

Results

KlimaLog is a unique and pioneering tool in the toolbox of the construction industry, using a vast data set to make climate actions easier to work with in daily business. This digital addition to STARK’s website, will increase the focus on sustainability and save the industry both time and money: it would take up to 14 days to collect all the new, documentation required by law. However, with KlimaLog, this documentation can be obtained within an hour. And customers have embraced their new tool: since its launch, around 400 customers have signed up for KlimaLog, and approximately 2,000 climate reports have been generated and downloaded.
