Starting in 2024, the new EU ESG-directive, CSRD, will require major listed European companies to increase documentation of their production’s environmental impact. The new directive also impacts distributors, where companies such as the plastic producer Carmo must now report more data on their environmental footprint than before.

However, the Danish company is well prepared for the new requirements, it has worked intensively for several years on mapping its environmental impact. The initiative has led to the development of Carmo’s own calculator under the designation, the Carmo carbon footprint calculator.

“Our data collection has come so far that we can calculate and report exactly what the individual parts of production contribute to the overall carbon footprint of a product. Including the climate impact from electricity consumption, transport emissions, and manufacturing of the raw materials, and the estimated production wastage on the finished product”, says Anders Johnsen, development and technology director at Carmo. He adds: “We can thereby provide a well-documented report of the carbon footprint, which also meets CSRD requirements.”

In addition to reporting the final environmental footprint of a product, the calculator also plays a decisive role in developing products with the customers. “With the new tool, we can make qualified design and improvement proposals based on data, because we can simulate design changes with the help of our carbon footprint calculator”, says Anders Johnsen. He adds: “This gives us optimal conditions for developing the exact solutions our customer needs. We also use it to document the effects of redesign and changes in the production of existing products.”

As an example, Anders Johnsen highlights Carmo's signature product, Super Valve, a unique turn valve for urine bags. Based on user feedback, Anders and his team improved the original design and production method of the valve to better suit the customers' needs. The redesign also achieved a 28 percent carbon reduction compared to a traditionally produced valve. This corresponds to 13.3 kilos less carbon emissions for every 1,000 valves produced. This has been documented through carbon calculations from Viegand Maagøe.

The valve now opens to 180° instead of the original 90°. This makes the product more user-friendly and takes up less space in both the open and closed state. The carbon reduction has been achieved through streamlining production, where the valve is produced in one piece on a single machine and with less material than in a traditionally manufactured turn valve.
