Ramboll launches open-access carbon benchmarking tool

Ramboll has launched an open access database to provide a means of benchmarking the decarbonisation of buildings.

Ramboll has launched an open access database to provide a means of benchmarking the decarbonisation of buildings.

CO2mpare provides a carbon analysis benchmark database with more than 130 buildings projects across six countries. According to Ramboll, the information it contains will enable buildings industry actors and governments to compare and benchmark their carbon reduction strategies.

The built environment significantly impacts society and nature, the company points out. Worldwide, buildings are responsible for 37% of global energy-related CO2 emissions, 34% of energy demand, and 50% of materials consumed.

Better quality and more consistent data is therefore critical to improving the sustainability of buildings, as it enables the industry and policymakers to draw comparisons and set sustainability benchmarks for specific building types.

Until now, this data has not been shared publicly, leading to slower uptake of best-practice solutions.

Lars Riemann, executive director for buildings at Ramboll, said: “We have a huge problem with the climate impact of buildings. The only way we can move forward is by sharing knowledge about what works and what does not work. As one of the leading advisors in the field, we see it as our responsibility to share our knowledge.”

With CO2mpare, Ramboll says its experts have developed a benchmarking database of building carbon footprints covering 10 different building typologies across their lifecycle.

“With the data we make available now, the key stakeholders in the building industry receive valuable input to their analysis basis,” Riemann added. “This transparency is expected to contribute to ambitious carbon targets for their building portfolios.”

The database is said to be the first open access tool of its kind. Initially, the majority of projects are located in Northern Europe, but Ramboll says that data from most continents will be consistently incorporated on an ongoing basis, to develop a more comprehensive global understanding of building decarbonisation.

Roland Hunziker, built environment director at the World Business Council for Sustainable Development (WBCSD), said: “To achieve a net zero built environment, we need urgent action and radical collaboration among all industry stakeholders, and that is why I applaud the steps Ramboll is now taking to create an open, shared data ecosystem.

“Harnessing data is one of the key interventions we have identified in the Market Transformation Action Agenda to deliver a transformation of the buildings market, and I hope other industry actors will follow Ramboll’s lead.”

The growing demand for more sustainable buildings is driven both by upcoming regulation and science-based targets for carbon emissions reduction. With ever increasing pressure to reduce carbon, investors and developers need to understand the typical level of carbon in buildings to make informed decisions. The assumption is that the lower carbon footprint a building has, the more interest there is to invest in it or be a tenant of it.

Riemann added: “Property developers and contractors want to reduce CO2 in their projects and ensure that it is an attractive investment object, and this new database is designed to help all industry actors benchmark their targets. And they have the investors behind them when, eg pension funds put their money into funds and decide that the fund should invest in buildings with targets for low carbon emissions.”
