re-lounge GmbH: Reducing the digital carbon footprint with Purement

The Freiburg-based digital agency re-lounge GmbH has developed Purement, an innovative cloud-based tool that accurately measures and reduces the carbon footprint of websites, online shops and apps.

Whilst many existing tools rely on assumptions and average values, Purement records actual carbon emissions. The tool therefore provides precise data and enables companies to analyse their digital CO₂ consumption independently and optimise it in a targeted manner.

Purement itself is a very compact tool, hosted on climate-neutral servers in Germany. It offers a unique basis for valid CO₂ reporting. With this solution, re-lounge is making an important contribution to sustainability in the digital sphere.
