One Click LCA Acquires SimaPro, Creating World's Largest Life Cycle Assessment Platform

One Click LCA announced in September 2025 that SimaPro and its developer PRé Sustainability have joined the One Click LCA family.

Key Points

• Combined platform includes over 500,000 LCA datasets across construction, manufacturing, chemicals, and other sectors

• Both SimaPro and One Click LCA continue as distinct products with their unique strengths

• The merged entity aims to reach one million users by 2035

• Joint investments planned in AI, supply chain data integration, and extended databases

What This Means for the Industry

The combination brings together two fundamentally different but complementary approaches to Life Cycle Assessment. SimaPro has built its reputation over three decades as the gold standard for transparent, science-based LCA modeling, particularly valued in academic and consulting settings. One Click LCA, meanwhile, has focused on making LCA accessible, scalable, and actionable for business users, especially in construction and manufacturing.

SimaPro users in construction and architecture-related industries are recommended to use One Click LCA, while users in other industries, research, and education should continue with SimaPro products.

Product Continuity Assured

For existing users, both companies have emphasized continuity. SimaPro and One Click LCA will remain distinct products, each optimized for different audiences but now strengthened by shared databases, joint investment in cloud services, and aligned quality programs. The SimaPro product family now includes SimaPro Craft (recommended for LCA practitioners and experts) and SimaPro Synergy (for business users with scaling plans). The traditional perpetual license model may shift toward One Click LCA's preferred subscription model to unify financial systems, though users are assured this could actually improve their experience through continuous updates.

Strategic Vision

The merger addresses the growing demand for high-quality sustainability data as regulations tighten worldwide. The combined platform supports compliance with major frameworks including the EU Construction Products Regulation, Energy Performance of Buildings Directive, and Ecodesign for Sustainable Products Regulation. Eric Mieras, Managing Director of PRé Sustainability, noted that joining One Click LCA enables them to accelerate PRé's mission to scale LCA while bringing scientific rigor to a far wider audience. Panu Pasanen, CEO and Founder of One Click LCA, described this as a pivotal moment for scaling LCA use.

What This Means for Users

For LCA practitioners, this consolidation signals several trends:

• Database expansion: Access to the combined 500,000+ datasets provides unprecedented coverage

• Interoperability: Expect improved data exchange between the platforms

• Training and support: The One Click LCA Academy combined with PRé's methodological expertise will expand learning resources

• Market positioning: The merger creates a dominant player that may influence industry standards and practices

What's Next

The integration roadmap centers on four priorities: user-friendliness, scalability, extended capabilities, and robustness. Practitioners should monitor announcements about feature integration, database harmonization, and potential changes to licensing structures. The deal was backed by PSG Equity and InfraVia, indicating substantial investment capacity for future development.
