🌊 Building Concrete That Stores Carbon
Can the world’s most essential building material become a climate solution?
We’re joined by Andreas Saari, Co-Founder & Co-CEO of Paebbl, a company developing carbon-storing materials that can be blended directly into concrete.
Cement is responsible for roughly 8% of global CO₂ emissions. The challenge isn’t just the energy required to produce it, half of the emissions come from the chemistry itself. In this conversation, Andreas explains why decarbonizing cement is one of climate tech’s hardest problems and why entirely new materials may offer a path forward.
We also explore what it takes to bring a novel industrial material to market, how risk is shared across the construction value chain, and why Europe could play a defining role in the next industrial era.
In our conversation, we covered:
→ Why cement remains one of the toughest sectors to decarbonize
→ How Paebbl turns captured CO₂ and abundant minerals into a carbon-storing construction material
→ Why customers increasingly demand low-carbon concrete—and who’s willing to pay for it
→ The challenge of proving performance when buildings and infrastructure are on the line
→ How Paebbl brought companies like Holcim and Amazon’s Climate Pledge Fund onto its cap table to align incentives
→ Why scaling industrial climate technologies requires a completely different financing model
→ Europe’s opportunity to lead a new wave of industrial innovation
→ The emerging software, AI, and materials technologies transforming the construction industry
