Thomas Mardahl – Founder of Rejoose and IT Carbon Impact Specialist As the founder of Rejoose, I am passionate about driving sustainability in the IT sector. Rejoose empowers IT providers, distributors, and resellers —including global IT leaders —with automated, activity-based carbon data for over six million IT products. This enables businesses to replace manual reporting with real-time data, ensuring informed decisions that reduce environmental impact.

Since 2019, I’ve been an active member of the EU Code of Conduct technical workgroup, contributing to industry standards. Rejoose also partners with leading research institutions to deliver scientifically grounded solutions that advance sustainability goals across the tech ecosystem.

By prioritizing accurate carbon data and collaboration, we aim to make sustainability a natural part of IT operations, helping the industry meet regulatory and stakeholder expectations while protecting our planet.
