Climate change caused by greenhouse gases are a global problem. Without seeking innovative ways to reduce CO₂ emissions, the problem will only worsen. Historically, global cement production has contributed up to 8% of these emissions and therefore producers have an opportunity to contribute to a solution.

At Argos, we believe that together we can transform our future by making changes today.

We engineered EcoStrong PLC as part of our goal to pursue zero net carbon emissions.
