【US】Decarbonizing Buildings in the U.S.: Policy, Procurement, and Practice

The United States is entering a new phase in building decarbonization. While whole-life carbon policies are less established than in Europe, federal and state initiatives, green building certifications, public procurement, and growing demand for low-carbon materials are beginning to reshape the building industry.

In this webinar, a California-based sustainability consultant Amy Leedham from Atelier Ten introduced the latest U.S. policy landscape and shared how building life-cycle assessment is being integrated into design practice. The session explored low-carbon material procurement, green certifications, project challenges, and practical lessons that can help architects, manufacturers, developers, and policymakers prepare for Japan's transition to building LCA.

Amy Leedham
Director, San Francisco, Atelier Ten

Amy Leedham is a Director of the San Francisco office and leads the US carbon practice. As a registered architect, Amy combines her expertise in building physics and architecture to foster communication between the design team and technical consultants in the pursuit of design excellence.
A recognized leader in addressing carbon emissions and enhancing human experience in the built environment, Amy develops innovative yet practical strategies to reduce the carbon impact and increase resiliency of buildings, masterplans, and portfolios. From navigating the technical and regulatory hurdles to advance high-rise mass timber construction, balancing forest health and supply chain challenges, to addressing energy diversification for resilience, Amy approaches projects with a holistic perspective, always keeping the bigger picture in focus.
Amy has delivered some of the firm’s most complex projects with ambitious goals such as net zero energy, zero water waste, enhanced occupant health, and carbon neutrality. Her diverse portfolio includes the UHS Women’s and Children’s Tower, 1265 Borregas, UCSC Kresge College, UC Merced 2020 Project, and the Sophie Maxwell Building.
Amy holds a BSc in Architecture from Northeastern University and an M.Arch in Sustainable Environmental Design from The Architectural Association in London. Beyond her work at Atelier Ten, Amy has taught at the University of California Berkely, The Academy of Art University, and the Architectural Association.

OVERVIEW [Webinar Series] How Will Building LCA Regulations Transform Industry Practice? Preparing for Japan's 2028 Building LCA Mandate
Japan is set to introduce a framework requiring the calculation and disclosure of whole-life greenhouse gas emissions for buildings with a gross floor area exceeding 5,000㎡, beginning in FY2028. While the details of the framework continue to be developed, stakeholders across the building sector, including project owners, architects, contractors, and building material manufacturers must begin preparing for its practical implementation. Across Europe, Building LCA has already become embedded in planning approvals, design development, material procurement, and investment decision-making. In North America, disclosure requirements and public procurement policies are accelerating demand for carbon data, reshaping both construction markets and supply chains. This webinar series explores what these international experiences can teach us about Japan's emerging framework. Looking beyond compliance, we will examine how Building LCA is influencing design choices, transforming material markets, and changing the way value and risk are assessed across the real estate and construction sectors. 　　　　　　　【France】From Regulation to Design Practice (7 July) 【UK】Practice-Led Building Decarbonization (31 July) 【US】 Policy, Procurement, and Practice (1 Sept)
