In this episode of All Things Circular, hosts Vic D’Arcy and Damian Polak sit down with Thomas Winther Mardahl of Rejoose to unravel one of the most misunderstood areas of sustainability today: accurate carbon emission data for IT products and why it’s quickly becoming a business essential, not just an ESG checkbox.

Together, Vic and Damian explore how carbon data has evolved beyond annual reports and virtue signaling, revealing how validated, activity-based carbon metrics are reshaping procurement, supply chains, and technology decisions. Thomas breaks down the shift from spend-based assumptions to real product-level lifecycle assessments, showing how better data leads to better decisions, longer lifespans, higher reuse value, lower emissions, and smarter investments.

The conversation delves into the significant impact of geography, energy sources, and repairability on a product’s footprint, including why two identical laptops can have drastically different carbon footprints depending on where and how they’re used. They also unpack the rise of digital product passports (DPPs), the EU’s new repairability index, and how global standards are pushing manufacturers and hyperscalers toward unprecedented transparency.

From the misconception that “recycling equals circularity,” to the emerging importance of avoided emissions and potential future Scope 4 reporting, the hosts challenge organizations to rethink how they measure and act on carbon. Thomas offers a clear and practical look at how businesses can integrate carbon data into their quoting systems, accounting platforms, and everyday decision-making to create a true competitive advantage.

By the end of this episode, you’ll see how accurate carbon data, circular thinking, and transparent reporting are redefining not just sustainability, but the future of IT itself.
