ACLCA 2026

ACLCA 2026 is a three-day conference dedicated to Life Cycle Assessment (LCA) taking place from 15 to 17 September 2026 in San Diego, California, United States, with optional professional development workshops on 14 September. The conference brings together practitioners from industry, consulting, government, academia, and NGOs to advance the methodology, application, and practical impact of LCA across sectors.

Purpose and Objectives

The primary purpose of ACLCA 2026 is to strengthen the practice and application of life cycle assessment by connecting professionals working across research, industry, policy, consulting, and sustainability. The event focuses on improving technical capability, sharing new methods and data approaches, and supporting wider use of LCA in product, policy, procurement, carbon, and sustainability decision-making.

Key Activities

The programme includes technical talks, special sessions, challenge sessions, poster presentations, committee open houses, networking events, and the LCA Institute, a dedicated learning track for professionals building or strengthening their LCA foundations. Pre-conference workshops on 14 September cover areas such as GHG accounting alignment, environmental product declarations, mass-balance methods, data workflows, biogenic carbon, land-use change, and advanced LCA modelling.

Significance

ACLCA 2026 is significant because it brings together the wider LCA community within one specialised professional forum, covering both methodological development and real-world application. Its cross-sector format allows practitioners to compare approaches, discuss emerging standards and data issues, and strengthen the role of life cycle thinking in environmental assessment and sustainability decision-making.

Expected Outcomes

Participants can expect stronger technical knowledge, practical approaches they can apply to LCA projects, and new professional connections across industry, research, consulting, and government. The conference is intended to support better modelling practices, greater consistency in assessment, collaboration between sectors, and wider adoption of credible life cycle information in business and policy decisions.
