2026 ACLCA Conference

The 2026 ACLCA Conference, hosted by the American Center for Life Cycle Assessment, takes place September 14–17, 2026 in San Diego, California, bringing together sustainability, LCA, and product-stewardship professionals for a leading North American gathering on life cycle assessment. Pre-conference workshops on September 14 provide focused, instructor-led training in specialized LCA methods, tools, and sector-specific techniques, with high-priority topics including greenhouse-gas accounting alignment, mass-balance approaches, Environmental Product Declaration and PCR development, data workflows, and advanced modeling. The main program (September 15–17) combines plenary sessions, peer-reviewed technical presentations, case studies, and roundtables spanning industrial, building, energy, transportation, agricultural, and consumer-product applications. Networking events — including the Welcome Reception and Awards Reception — support community-building across practitioners, academics, consultants, regulators, and corporate sustainability teams active in the LCA field.
