US: A team from the University of Colorado Boulder (UCB) has developed a carbon-neutral alternative cement from biogenic limestone. The limestone comes from farmed cocolitophores, which capture CO₂ as they grow.

The UCB scientists collaborated with colleagues from the University of Carolina at Wilmington and the National Renewable Energy Laboratory on the project. Their work has received US$3.2m in US Department of Energy funding.
