Amazon & Holcim to invest in startups for sustainable construction

Holcim and Amazon’s Climate Pledge Fund are teaming up to invest in two innovative startups, 14Trees and Paebbl, to advance sustainable construction practices. Amazon’s Climate Pledge Fund is contributing to 14Trees, alongside Holcim’s follow-on investment in its 3D printing joint venture with British International Investment (BII). This will accelerate the startup’s efforts in constructing large-scale, low-carbon buildings, including data centres. The investment in Paebbl, part of a larger funding round, will help scale the company’s advanced mineralization technology, which aims to store CO2 permanently in concrete, transforming it into a carbon sink.

Nollaig Forrest, Chief Sustainability Officer at Holcim said, “By investing with Amazon’s Climate Pledge Fund into 14Trees and Paebbl, we can scale up these pioneering technologies to push the boundaries of sustainable building, from 3D printing to making concrete a carbon sink.”

Francois Perrot, Managing Director, 14Trees said, “We are excited to count Amazon and Holcim as investors in 14 Trees, to take our successful 3D-printed technology from homes and schools to data centers, to deliver low-carbon and high-performance buildings.”

Marta Sjögren, co-founder and co-CEO, Paebbl stated, “We are thrilled to welcome first movers in their respective fields, Amazon and Holcim, as first commercial partners to bring our vision to market. This funding round enables us to take even bolder steps in our mission to make the built environment a cornerstone of the decarbonized economy.”

14Trees, established in 2016 as a joint venture between Holcim and BII, has been at the forefront of sustainable construction solutions in Africa, delivering the first 3D-printed house on the continent, the world’s first 3D-printed schools, and one of the largest 3D-printed neighborhoods globally.

Paebbl, founded in 2021, transforms CO2 into an innovative industrial material that turns buildings into permanent carbon stores. The company was created by serial entrepreneurs Andreas Saari and Jane Walerud, mineralization expert Pol Knops, and former venture capitalist Marta Sjögren.
