What C.Scale does
C.Scale is a whole life carbon data platform that streamlines building carbon assessments from concept through construction, built originally inside architecture firm EHDD and spun out as an independent Delaware public benefit corporation in November 2024. The platform's AI-powered calculation engine generates construction specifications and life-cycle carbon estimates (covering A1-A5, B, C, and D phases) from as few as six basic project inputs, producing results in under 10 minutes that the company claims fall within 5% of detailed life cycle assessments. Core modules cover predictive carbon modeling, detailed assessments, low-carbon product sourcing via Environmental Product Declarations, portfolio benchmarking, and automated reporting through AIA 2030 DDx exports, with a public API and native integration into Autodesk's BIM tools and Schneider Electric's building decarbonization products.
The business runs a freemium SaaS model: individuals and organizations can sign up for free accounts (organizations get up to 3 projects free), while paid organization subscriptions unlock unlimited projects, collaboration, chart exports, and AIA DDx reporting on an annual auto-renewing basis. C.Scale serves primarily North American architecture and engineering (A&E) firms, with an additional manufacturer-facing product variant and downstream exposure to building owners and real estate firms via partner platforms. Adoption metrics cited by the company include 200+ A&E firms, 1,000+ active projects, and 120+ million square feet of construction under assessment. The November 2025 $2M pre-seed round led by Wireframe Ventures and Active Impact Investments and the April 2026 acquisition of the Tally LCA tool from Building Transparency are the most significant capital and M&A actions to date.

C.Scale product offering
Product offeringCore offering
C.Scale provides an AI-enabled whole life carbon data platform that streamlines carbon assessments for building projects from concept through construction. The platform enables architecture, engineering, and building product manufacturing firms to model project carbon emissions in 10 minutes or less, benchmark against industry standards, source low-carbon products via Environmental Product Declarations (EPDs), and automate compliance reporting for LEED, AIA 2030 DDx, and NYC Local Law 97. It serves 200+ A&E firms across 1,000+ active projects covering 120+ million square feet of construction.
Product overview
C.Scale is a whole life carbon data platform offering a unified product-plus-modules architecture. The core C.Scale Platform provides integrated carbon assessment workflows from concept through construction, supported by five primary modules: Predict Carbon Emissions (concept-level forecasting), Perform Detailed Assessments (LCA building), Find Low-Carbon Products (EPD sourcing), Benchmark Your Portfolio (comparative analytics), and Streamline Reporting (AIA 2030 DDx automation). The company acquired the Tally LCA tool from Building Transparency and is developing Tally 2.0. An AI-powered whole life carbon calculation engine (embedded in Autodesk and Schneider Electric integrations) and a public API extend the platform's capabilities. A manufacturer-facing variant enables product suppliers to connect with designers. The platform supports over 1,000 active projects across 200+ A&E firms.

C.Scale competitors and assessment
Company assessmentBroad incumbents
- Sphera: Sphera provides enterprise sustainability, EHS, and product LCA software including building- and construction-related modules. It overlaps with C.Scale on LCA and ESG reporting functionality, particularly for large building product manufacturers and corporate real estate customers.
- Autodesk (Forma / Insight / Revit Sustainability): Autodesk provides BIM and sustainability tooling (Forma, Insight, Revit) to virtually every major A&E firm. While currently an integration partner to C.Scale, Autodesk is also a potential competitor that could internalize whole-life carbon calculation, putting pressure on C.Scale's distribution and pricing.
- Microsoft Sustainability Manager: Microsoft Sustainability Manager is an enterprise cloud-based ESG and carbon data platform that includes facilities and supply-chain emissions modules. It competes with C.Scale for corporate real-estate and Scope 3 reporting budgets at large enterprises and building owners.
- Persefoni: Persefoni offers an AI-enabled carbon accounting and climate management platform for enterprises across multiple sectors. It competes with C.Scale primarily for building-owner/REIT decarbonization budgets and corporate Scope 3 reporting mandates that include embodied carbon from real estate.
- Watershed: Watershed is an enterprise climate platform for corporate carbon accounting and disclosure, including built-environment emissions. It overlaps with C.Scale at the building-owner/REIT portfolio benchmarking segment and represents a broader-scope competitor for portfolio-level carbon reporting budgets.
Direct peers
- One Click LCA: One Click LCA is the most established SaaS platform for building life-cycle assessment and embodied carbon calculations, used by A&E firms globally. It is a direct competitor to C.Scale's concept- and detailed-stage carbon assessment modules, especially in international markets where C.Scale has limited presence.
- EC3 (Embodied Carbon in Construction Calculator): EC3, operated by Building Transparency, is the leading free database and tool for A&E firms to look up EPD-based embodied carbon intensities. It is integrated with C.Scale today but competes for the same design-stage carbon workflow and material-sourcing use cases.
Emerging players
- Briq: Briq is a construction financial planning and analytics platform with emerging sustainability and carbon forecasting capabilities. It targets the same GC and A&E customer base as C.Scale and is expanding into project-level carbon analytics, making it a partial overlap competitor for design-phase decarbonization workflows.
Others
- KieranTimberlake: KieranTimberlake is the architecture firm behind Tally and a strategic partner supporting C.Scale's Tally 2.0 development. It is an adjacent ecosystem participant — a thought-leading A&E firm and co-developer rather than a commercial direct competitor.
- Arup / Mott MacDonald LCA practices: Major engineering consultancies like Arup and Mott MacDonald run large in-house LCA and whole-life carbon consulting practices serving A&E firms and owners. They represent an adjacent service model — outsourced human LCA consulting — that competes with parts of C.Scale's detailed assessment workflow and could partner with or displace software-led approaches.
