OneClick LCA - Great for Concrete Manufacturers
"One Click LCA is an easy to use platform, making it fast and efficient to publish EPDs at scale, with a great support team."
"I like that One Click LCA is easy to use and guides me through the process. It includes supportive videos and staff assistance if needed. The software allows customization of EPDs, which I find really useful. I appreciate having access to a library of supportive information, videos, and documents, making it accessible anytime from anywhere. The initial setup was very simple and the software walked me through the necessary steps."
Clear Onboarding and Cohesive Sustainability Workflows in One Click LCA
"One Click LCA was my first hands‑on exposure to carbon measurement and sustainability, introduced in clear and manageable steps. I valued the structured guidance and strong onboarding support. The platform connects core sustainability elements—from EPDs and standards such as BREEAM and RICS to practical workflows including Revit integration—into a cohesive experience."
Streamlined EPD Management Saves Time
"I find One Click LCA incredibly beneficial because it makes Environmental Product Declaration (EPD) work both easier and quicker, particularly in my role as a consultant. I appreciate the availability of supplier EPD data within the software, which means I don't have to manually include these details as I would with other software. The feature that allows automatic searching for EPDs directly from within the software is a substantial time-saver and enhances efficiency by reducing manual data entry. "
One Click LCA Makes EPD Development Efficient, and Well-Supported!
"What I like most about One Click LCA is how it simplifies a very complex process like EPD development. The platform provides a clear and structured workflow, making it easier to compile, manage, and verify large amounts of data efficiently. The integration with reliable databases and the ability to generate documentation in a streamlined manner saves significant time and effort."
Simplifies Carbon Assessments with Intuitive Features
"I find One Click LCA incredibly easy to use, which makes my daily tasks of performing carbon assessments much more efficient and straightforward. The comprehensive and expansive Environmental Product Declaration (EPD) database is a significant asset, providing a rich resource to draw from when quantifying carbon in both new and old constructions. The clear and concise graphical representations of carbon in buildings stand out to me, as they vividly highlight where the majority of carbon is concentrated within a project. I especially appreciate how One Click LCA offers material alternative suggestions, which guide me in making informed decisions to mitigate embodied carbon effectively. The software’s initial setup was very smooth, which only adds to its overall user-friendliness. Ultimately, these features combine to make One Click LCA an invaluable tool in my work, deserving of a high recommendation rating of 10 out of 10."
