New Managing Director Tobias Laurens Strengthens CSC’s Sustainability Mission
As the Concrete Sustainability Council (CSC) celebrates the 10th anniversary of its global responsible sourcing certification, the organization welcomes Tobias Laurens as its new Managing Director. With nearly a decade of experience in and around the concrete sector, Laurens brings a strong commitment to measurable sustainability, transparency, and continuous improvement across the value chain.
He is motivated by the belief that the concrete industry can—and must—advance toward lower carbon, greater circularity, and more responsible sourcing. Laurens sees CSC as a vital framework for guiding companies through a complex sustainability landscape, helping them move from ambition to credible, verifiable action.
In his first months, he aims to listen, learn, and build clarity within the organization, followed by strengthening CSC’s strategic direction and global influence, with renewed emphasis on North America. Laurens looks forward to collaborating with certified companies and partners to expand CSC’s impact and support a more sustainable built environment.

Live Event: Concrete Innovations: Pathways to Reducing Carbon Footprint
CONEXPO-CON/AGG | Register
March 5, 2026 - 1:00 - 2:00 PM Pacific
Las Vegas Convention Center
Join Lionel Lemay, Founder and CEO of ConcreteNexus and Brian Killingsworth, Executive Vice President of NRMCA for their session on pathways to reducing the carbon footprint of concrete. Cutting-edge building projects must use durable materials that also help reduce carbon footprint. Concrete is the material of choice for the tallest buildings in the world and infrastructure designed to last centuries. This session explores how new products using pozzolans, calcined clay, biochar, and other innovations enhance a product that is nearly 5,000 years in development and provides another pathway for meeting future challenges in the built environment. This presentation includes the histories, compositions, and environmental impacts of these technologies and offers case studies to show how innovation is being put into action.
