Soletair Power and Carbonaide are addressing one of the most pressing environmental challenges: reducing carbon dioxide (CO₂) emissions in the construction industry. Together, they are turning harmful CO₂ emissions into something of value as part of a key step to achieving the global climate goals presented by the IPCC. The partnership is oriented toward reversing emissions from buildings, which account for nearly 40% of global CO₂ emissions.
Capturing and Reversing Emissions in Construction
In December 2024, Carbonaide successfully produced net-negative concrete by utilizing CO₂ captured from Soletair Power’s innovative direct air capture technology. This partnership reduces reliance on high-carbon cement while turning concrete into a permanent carbon sink, locking CO₂ away permanently. This technology reduces the overall carbon footprint of concrete production, helping to lower costs while contributing to climate-positive construction practices.
Tapio Vehmas, CEO of Carbonaide said, “We are solving two problems at once. By reducing cement use, our customers will benefit from significant cost savings but also gain competitiveness in their business while EU ETS regulations are tightening. At the same time, we ensure that captured CO₂ stays out of the atmosphere for good.”
Turning Emissions into Value
Petri Laakso, CEO of Soletair Power, stated that the partnership highlights the strengths of both technologies. He compared it to turning harmful emissions into valuable solid minerals, creating value by reducing costs and effectively closing the loop for air-captured CO₂.
Soletair Power’s technology integrates direct air capture with building ventilation, efficiently removing CO₂ while saving energy in the process. This process not only helps reduce a building’s carbon footprint but also improves urban air quality. Carbonaide uses captured CO₂ to replace cement in concrete, transforming a major carbon-emitting industry into a long-term carbon sink.

A Path Toward Net-Negative Buildings
The partnership between Soletair Power and Carbonaide paves the way for a future of net-negative emissions in the built environment. By capturing CO₂ directly from building airflows and turning it into durable, carbon-storing concrete, these technologies offer a tangible solution to one of the world’s most difficult climate challenges.
