Reducing Concrete’s Embodied Emissions: A Toolbox from innovation in materials to Industrial-Scale CCUS
November 17, 1-2 pm Eastern
Presented by Sergio Tortelli | Heidelberg Materials
Claire Nowasell | Heidelberg Materials North America
Hosted by Lionel Lemay, PE, SE, LEED AP | ConcreteNexus
This free online seminar will introduce two innovative and complimentary technologies for reducing concrete’s embodied carbon. CCUS (Carbon Capture Utilization and Storage) and its related EACs (Environmental Attribute Certificates) and enhanced carbon mineralization in recycled concrete paste.
CCUS is widely recognized as a critical technology to address calcination emissions from clinker production. The webinar will show how CO2 which is captured, verified, and permanently stored is tracked, accounted for and made available to reduce a project’s embodied emissions.
ReConcrete uses specific concrete recycling technologies to selectively recover cement paste for CO2 mineralization yielding aggregate and or supplementary cementitious materials which can be incorporated into blended cement or directly into concrete.
Please join us to get more details on these emerging technologies and how they can decarbonate your projects and lower concrete’s embodied carbon.

THE FUTURE OF CONCRETE WEBINAR SERIES
Sponsored by Climate Earth and hosted by Lionel Lemay of ConcreteNexus, The Future of Concrete explores how the industry is rapidly evolving to meet new expectations for sustainability, performance, and transparency. Each monthly session features practical, real‑world conversations with producers, designers, owners, and policymakers who are shaping the next generation of low‑carbon, high‑performing concrete. From EPD‑driven specifications and responsible sourcing to LEED, Envision, and emerging policy trends, the series highlights what’s changing in the market—and what it means for competitive, resilient project delivery. Join us to stay ahead of the curve and understand where concrete is headed next.
Cements for Modern Concrete Construction
October 14, 2026
2 PM Eastern | 11 am Pacific
Online
Blended cements are creating new opportunities to improve concrete performance while supporting lower carbon mix designs.
Eric Koehler, Ph.D., P.E., Vice President of Innovation at Titan America, will be joining this webinar alongside Drew Schlegel from Climate Earth, along with Lionel Lemay from ConcreteNexus.
In this webinar, we’ll cover:
- How Titan America developed TriForce Cement to address water demand, finishability, consistency, and durability
- How blended cements can give producers greater flexibility with SCMs and mix design
- How Climate Earth helps producers evaluate mix designs and understand environmental impacts
Innovative Materials For Low Carbon Concrete
November 11, 2026
2 PM Eastern | 11 am Pacific
Online
New materials are creating new opportunities to reduce the carbon impact of concrete while maintaining the performance producers need.
Join Mark Masotti from alterBiota and Lionel Lemay from ConcreteNexxus for a discussion on the emerging materials and technologies shaping the next generation of low-carbon concrete.
In this webinar, we’ll cover:
- Emerging materials being used to reduce concrete’s environmental impact
- How alternative SCMs, biochar-based technologies, and other innovations can be incorporated into concrete
- What producers should consider when evaluating performance, durability, and real-world use
- How these materials could change the way lower carbon concrete is designed and produced
Designing With Low-Carbon Concrete — What Architects & Engineers Need to Know for 2027
December 9, 2026
2 PM Eastern | 11 am Pacific
Online
Join host Lionel Lemay, Founder and CEO of ConcreteNexus along with an expert panel as they explore how designers can confidently specify low-carbon concrete using clear performance data, EPDs, and realistic GWP targets. They will present what producers are actually able to deliver in 2026: mix performance, SCM availability, ACI compliance, and carbon reduction pathways. They will discuss how architects, engineers, and producers can align early in design to meet LEED v5, Buy Clean, CALGreen, and owner-driven carbon goals without adding project risk.

Advancing Net Zero Goals Through Responsible Sourcing of Concrete
Net Zero Conference 2026
October 8, 2026 | Los Angeles Convention Center
Concrete’s global scale makes it essential to any credible net zero strategy. Responsible sourcing provides a practical, verifiable pathway to reduce the material’s carbon footprint while improving transparency and performance across the supply chain. Certification frameworks such as the Concrete Sustainability Council (CSC) help project teams evaluate environmental stewardship, ethical practices, and continuous improvement from raw materials through ready mix production. By prioritizing lower carbon cement blends, optimized mix designs, renewable energy, efficient quarry operations, and circular practices like recycled aggregates, responsible sourcing directly reduces embodied carbon. It also supports compliance with LEED v5 and emerging owner requirements for low carbon procurement. This session, presented by Lionel Lemay of Concrete Sustainability Council and Lawson Sanford of Climate Earth, will show how responsible sourcing accelerates market transformation and enables concrete to meaningfully contribute to global net zero commitments.
The Business Case for Responsible Sourcing in Advancing Green Building Goals
October 18, 2026 | 2:30 - 3:00 PM
NRMCA Concrete Works | Nashville, TN | October 15-18, 2026
Responsible sourcing is increasingly essential to green building and low-carbon construction as LEED, Envision, and procurement policies emphasize transparency, ethical practices, and value-chain accountability. Tobias Laurens, Managing Director of CSC, and Lionel Lemay, Business Development Director, North America, will explain how Concrete Sustainability Council certification helps concrete producers verify environmental, social, governance, and economic performance. CSC certification can support project teams pursuing green building credits while helping producers reduce operational and regulatory risk, strengthen supply-chain resilience, expand market access, and meet demand for responsibly sourced materials. The session positions responsible sourcing as both a sustainability imperative and competitive business advantage.
Reducing Wildfire Losses: Practical Strategies for Homes, Businesses, and Communities
October 26, 2026 | 1:00 - 2:00 Eastern
Online
Wildfires are becoming more frequent, more destructive, and more costly across North America. Yet proven strategies exist to reduce losses before disaster strikes and improve recovery afterward. Join experts in community resilience, wildfire preparedness, and resilient construction for a practical discussion on how communities, homeowners, businesses, and policymakers can better prepare for wildfire risk. Learn how science-based mitigation programs, resilient planning practices, proper landscaping and vegetation management, and non-combustible building materials can help reduce property losses, protect investments, and support faster recovery after a wildfire. Attendees will leave with actionable insights for building more resilient communities and buildings in an era of increasing wildfire risk.
This webinar is presented by Pacific Northwest Building Resilience Coalition and supported by Pacific Northwest Economic Region.
Strategies for Sustainable Product Procurement in Envision
November 4, 2026 | 4:30 - 5:30 PM Eastern
