    310: RB26 Solutions Series: Materials with Carbon Leadership Forum

    In this episode of the Passive House Podcast, Ilka Cassidy talks with Meghan Lewis, Program Director at the Carbon Leadership Forum (CLF), ahead of CLF's three-hour Materials programming block at Reimagine Buildings ’26: The Solutions on November 6. Meghan walks through CLF’s Embodied Carbon State Policy Playbook, highlighting states leading the way on policy and the challenges of turning legislation into action. The conversation explores who still needs a seat at the table, particularly developers and contractors who hold the cost data policymakers need. Meghan also shares how CLF’s 26 volunteer-led hubs and professional commitment programs like SE 2050 are helping spread knowledge and accelerate progress, and why embodied carbon policy must address housing rather than treating it as off-limits. The conversation offers a preview of CLF's three-hour Materials block at Reimagine Buildings ’26, which will bring together industry leaders to explore the policies, tools, and innovations driving embodied carbon reduction. Sessions will cover state-level policy, whole-building life cycle assessment benchmarking, and the hidden carbon impacts of MEP systems, followed by innovations in ultra-low-carbon concrete and biobased building materials. The programming will conclude with a panel on making low-carbon, affordable housing a reality, exploring how incentives, carbon accounting tools, and practical building strategies can help scale housing production without scaling emissions.  View the full program here:https://events.ringcentral.com/events/reimagine-buildings-26/registration Register for Reimagine Buildings ’26: The Solutions:https://events.ringcentral.com/events/reimagine-buildings-26/registration Learn more about the Carbon Leadership Forum:https://carbonleadershipforum.org/ Join us on the Reimagine Buildings Collective:https://collective.reimaginebuildings.com/
