294: Beyond Operational Carbon: Rethinking Cement, Steel, and Embodied Carbon

In this episode of the Passive House Podcast, Jay Fox talks with Mikhail Haramati, NRDC's state industrial decarbonization lead, about her path from California energy efficiency programs and policy work at UC Berkeley and LBNL, through the California Energy Commission and NYSERDA, to her current focus on embodied carbon in building materials.

They discuss the scale of the problem (cement and concrete alone account for about 8% of global emissions) and state-level policy momentum like Buy Clean initiatives and New York's Executive Order 22, which mandates EPDs and sets GWP limits for key materials. The conversation covers pathways to decarbonization—reuse and deconstruction, steel's reliance on recycled scrap and hydrogen-ready direct reduced iron, lower-clinker concrete mixes and SCMs, and mass timber—along with practical first steps for designers and policymakers: better data, smarter specs, and the right incentives and financing tools.
