Portland Cement Association members aim to finalize next year a template to achieve carbon neutrality across the concrete value chain by 2050. A roadmap will likely factor data-driven process and practice metrics: From cement mills’ raw material extraction and kiln fuel, to concrete producers’ promotion of supplementary cementitious materials-rich mix designs, to contractors’ finishing of slabs or structures credited with carbon dioxide absorption capacity.
“As the second most used material on earth and a cornerstone of our economy, we understand the critical role cement and concrete play in our nation’s future, and are committed to an industry-wide effort that achieves carbon neutrality,” says PCA Chairman Tom Beck (Continental Cement). “We look forward to proactively working with stakeholders across the built environment, policymakers and environmental groups toward this ambitious target.”
Strategies supporting carbon neutrality attainment will extend an environmental track record for U.S. cement producers, who since 1990 have reduced energy consumption by 35 percent and clipped emissions intensity per ton of delivered powder by 11 percent. PCA roadmap development dovetails efforts by other North American industries, environmental groups and government agencies to mitigate the effects of climate change and create a more sustainable future. It stands to position cement and concrete interests as leaders in the construction sector in delivering cleaner, greener infrastructure.
