Reinventing Cement: CURA’s Path to Reducing CO₂ Emissions

Global average atmospheric carbon dioxide (“CO₂”) concentrations have climbed roughly 25 percent since 1980. This is largely driven by fossil fuel combustion and intensifying wildfires, as the planet’s natural CO₂ sinks lose their capacity to keep up. One of the industries sitting at the heart of the climate dilemma is cement. While foundational to modern infrastructure, its production accounts for approximately 8 percent of global CO₂ emissions.

CURA Climate Inc. (“CURA”) is confronting this challenge with a potentially transformative advance. The company has developed an electrochemical technology that can reduce the CO₂ emissions of cement manufacturing by up to 85 percent. CURA’s technology can fit into existing operations. Powered by electricity, the process integrates with current feedstocks and infrastructure and can split limestone into lime and a pure stream of CO₂. The result is zero-CO₂ lime that can then be used to produce low-CO₂ cement, eliminating emissions upstream.

CURA emerged from research at the University of British Columbia and is led by some of Canada’s most accomplished climate technology innovators. Erin Bobicki, co-founder and CEO of CURA, described the significance of its climate impact: “Cement is one of the hardest climate challenges left to solve and the world cannot reach net zero without rethinking how it’s made. With CURA, we’re offering a retrofit-friendly, scalable solution that eliminates process emissions without forcing producers to change their feedstocks or infrastructure.”

CURA’s momentum is building. It was accepted into the Creative Destruction Lab’s Climate Stream in Paris, one of the world’s leading programs for scaling science-based ventures. Looking ahead, the team is focused on expanding its electrochemical process through a pilot program, followed by a 10,000-tonne demonstration facility in the coming years. This next phase will be pivotal for validating performance under real industrial conditions and accelerating the path to commercialization.
