What C-Change Labs does
C-Change Labs is a Canadian software company founded in 2017 and based in Coquitlam/Vancouver, British Columbia. It builds bimCAT, a free, open-access Autodesk Revit plug-in (compatible with Revit 2020-2024) that automates embodied carbon assessment for buildings and infrastructure. The tool is powered by the company's proprietary Carbon Quantity Data (CQD) database, which aggregates manufacturer-specific Environmental Product Declarations (EPDs) and links into the OpenEPD network operated by BuildingTransparency Canada Society.
The product is engineered for architecture, engineering, and construction (AEC) practitioners — primarily architects, structural engineers, and sustainability consultants — who need to quantify embodied carbon within their existing BIM workflows rather than via standalone LCA tools. bimCAT ships AI-assisted material suggestions to help users navigate the underlying EPD library and select lower-carbon material options, and the bimCAT Library Browser extends the product surface into material-data discovery. Distribution is anchored on the Autodesk App Store, with co-development and adoption signals from Perkins&Will, ZGF Architects, and KT Innovations, and the project has received direct funding from the Province of British Columbia.
C-Change Labs operates a freemium, non-license revenue model: the software itself is free, and the company is sustained by government grants, partner contributions, and ecosystem affiliations rather than paid subscriptions. In October 2024 the company was acquired by WAP Sustainability (now part of SLR Consulting), folding bimCAT into a global sustainability consulting platform and changing its go-to-market from independent open-source tool to embedded advisory product.

C-Change Labs product offering
Product offeringCore offering
C-Change Labs develops bimCAT, a free, open-access Revit plug-in that exports material quantities from BIM models, synchronizes them with a web application backed by the proprietary CQD database, and enables architects and engineers to perform embodied carbon assessments using third-party verified Environmental Product Declarations (EPDs). The product automates carbon hotspot visualization and report generation directly within the Revit workflow, targeting sustainable building design and ESG reporting.
Product overview
C-Change Labs provides a unified product ecosystem centered on bimCAT (BIM Climate Action Tool), a free and open-access Revit plug-in for embodied carbon assessment in the building industry. bimCAT is powered by the CQD database and includes a Library Browser module for managing Revit Families with embedded sustainability data. The company also supports the OpenEPD platform, which is linked through its main website. Together, these offerings enable architects and engineers to select materials based on project needs, assess embodied carbon reduction opportunities, and produce charts and reports directly within Revit.

C-Change Labs competitors and assessment
Company assessmentBroad incumbents
- IES (Integrated Environmental Solutions): IES provides a broad building-performance suite including energy, daylighting, and LCA modules used by AEC firms. Comparable to bimCAT as an AEC sustainability tool, but operates as a multi-module enterprise platform rather than a free Revit plug-in.
- Sefaira (Trimble): Sefaira, owned by Trimble, offers energy and sustainability analysis tools aimed at architects and building designers. It overlaps bimCAT on the sustainability-analysis-for-AEC dimension and competes for practitioner mindshare within design-phase workflows.
- Sphera: Sphera provides enterprise sustainability, EHS, and product-stewardship software, including LCA tools that touch built-environment customers. It is comparable to C-Change Labs in the corporate carbon/environmental data space, though oriented to large enterprises rather than AEC practitioners in Revit.
- Autodesk Insight: Autodesk Insight is the building performance and sustainability analysis tool native to Revit and FormIt, covering energy, carbon, and daylighting. It overlaps bimCAT's Revit-embedded sustainability workflow and represents Autodesk's own answer in the same category, making Autodesk both a platform partner and a competitor.
Emerging players
- Madaster: Madaster offers a materials passport and circularity platform for the built environment, with EPD-driven embodied-carbon features. It overlaps with bimCAT in linking building-material data to carbon impact, but focuses on asset/material passports rather than a Revit-side workflow.
- Cove.tool: Cove.tool provides building performance and sustainability analysis for AEC, with daylighting, energy, and embodied-carbon features. It overlaps bimCAT on the sustainability-for-AEC intersection and targets similar practitioner personas, though broader in scope than embodied carbon.
Direct peers
- Athena Sustainable Materials Institute: Athena provides LCA-based environmental impact tools for buildings (Athena IE, Impact Estimator) targeting AEC professionals. Comparable to bimCAT in the building-embedded-carbon assessment category, though with a research-institute provenance rather than a plug-in product.
- One Click LCA: One Click LCA is a leading software platform for life-cycle assessment and embodied carbon in construction, serving architects, engineers, and contractors globally. It overlaps directly with bimCAT in the embodied-carbon-for-AEC use case and competes for the same EPD-data-driven workflow.
- EC3 (Embodied Carbon in Construction Calculator): EC3, operated by Building Transparency (a direct C-Change Labs partner), is a free, open-access tool for assessing embodied carbon in construction using EPDs. It is the most direct comparable in terms of open-data approach, EPD-centric design, and free distribution model targeting the same AEC audience.
- Tally (by KT Innovations / Thornton Tomasetti): Tally is a Revit plug-in for whole-building LCA and embodied carbon assessment, closely comparable to bimCAT in target user (AEC practitioners), platform (Revit), and workflow (EPD-linked carbon calculation). KT Innovations even contributed to bimCAT's design, confirming direct category overlap.
