A SOLID FOUNDATION FOR LOWERING CARBON FOOTPRINTS


TRANSFORMING CONCRETE FROM A CARBON PROBLEM TO A CARBON SOLUTION


verify the claims made by the promoters of these innovations. Accurately measuring the veracity of claims has become a key issue in the private sector’s Voluntary Carbon Market (VCM), which is increasingly emphasising

the need to monitor, verify, and report the amount of CO2 that is actually captured and stored. Carbonaide, a Finnish company serving the concrete industry, has a clear answer to this challenge – and it is


market-ready. Carbonaide’s technology utilises CO2 to produce a carbonate mineral. With support and cooperation from the measurement technology company Vaisala, Carbonaide’s solution is practical and straightforward, and underpinned by accurate monitoring.


BIG CHALLENGES CALL FOR SMART SOLUTIONS


Climate changing CO2 emissions come from many sources, but the concrete industry alone emits eight per


cent of global CO2, mostly in the form of emissions from standard Portland cement manufacturing. As a major global contributor of greenhouse gas emissions, the concrete industry is under enormous pressure to lower its carbon footprint. A single ton of Portland cement creates


an astounding 800–900 kilograms of CO2 emissions, and with regulations increasingly tightening around concrete production emissions, efficient technologies to reduce the


CO2 emissions from concrete are in high demand. The challenges are several-fold: How to remove CO2? Where to store it? How to do this affordably? And – just as


importantly – how to accurately measure performance? Simply stated, Carbonaide’s expertise is in the transformation of concrete from a large emission source into a carbon storage sink. The company’s CEO is Tapio Vehmas, an analytical chemist by training with more than 20 years of experience in the concrete sector. He is one of

s the climate continues to warm, so does the demand for technologies that can reduce


CO2 emissions and/or efficiently remove CO2 from the atmosphere. Proposed solutions for sequestering CO2 are plentiful, but there are serious issues around how to
