One Click LCA becomes world's first RICS-validated whole-life carbon assessment software

Helsinki, Finland (July 03, 2025) – One Click LCA, the sustainability platform for construction and manufacturing, is proud to announce that it has become the world's first software platform validated by the Royal Institution of Chartered Surveyors (RICS) through their newly launched Whole Life Carbon Assessment (WLCA) Software Validation Programme.

This validation affirms that One Click LCA enables users to generate reports that are compliant with the RICS WLCA standard (2nd edition) — the globally recognized framework for consistent, transparent, and comparable whole-life carbon assessments across the built environment.

“We are proud that One Click LCA is the first platform to be validated by RICS through its Whole Life Carbon Assessment Software Validation Programme. This milestone underscores our long-standing commitment to enabling transparent, standardized, and high-quality environmental impact assessments. We look forward to supporting the industry with RICS and driving progress toward a decarbonized future.”

- Panu Pasanen, CEO at One Click LCA.

Rigorous independent validation

The RICS validation programme is designed to provide confidence to professionals using carbon measurement software. It evaluates whether a software solution:

• Accepts inputs and performs calculations in accordance with the mandatory requirements of the WLCA standard.
• Outputs results aligned with the WLCA reporting template in an acceptable digital format.

One Click LCA is validated  across all assessed life-cycle stages, including upfront carbon (A1–A5), in-use emissions (B1–B5), operational carbon (B6-B7), end-of-life carbon (C1–C4), and beyond life-cycle benefits (D1–D2), as well as biogenic carbon tracking. The platform received validation for the assessment of buildings and life-cycle modules critical to whole life carbon performance.

"The RICS WLCA Software Validation Programme is a critical step in bringing consistency to how carbon emissions are measured and reported across the built environment. By validating tools against our WLCA standard (2nd edition), we are helping professionals make consistent, standard-aligned decisions that support the delivery of low-carbon, resilient assets. We are pleased to announce that One Click LCA is the first software to be validated through this programme. This marks an important milestone in advancing credible, standard-based whole life carbon assessments."

- Anil Sawhney, Head of Sustainability at RICS

A step forward for industry alignment

The RICS WLCA standard (2nd edition) is fast becoming a cornerstone for carbon reporting and regulatory alignment in the construction and real estate sectors. One Click LCA’s validation makes it easier than ever for professionals to meet their WLCA reporting requirements and demonstrate compliance with leading benchmarks.
