Variable

Core Features

Variable uses a supply-chain–aware LCA methodology combining background LCI data with primary supplier and operational inputs, aiming to support dynamic, product-level footprinting that evolves as the product changes. Its design emphasises scalability, data quality and integration with manufacturing workflows. Within that framework, some of its main capabilities are:

• Dynamic Supply-Chain LCAs — Variable builds a live data model for each product’s supply chain so carbon footprints and EPDs update automatically when materials, processes or suppliers change.

• Primary Data Collection & Supplier Data Exchange — The platform supports flexible data exchange from suppliers, enabling companies to replace generic averages with supplier-specific data for improved footprint accuracy.

• Automated Data Integration & Workflow — Integrates with core data systems via API to import BOMs, material lists and other data automatically, reducing manual effort while keeping calculations audit-ready.

• Verified PCFs and EPD Generation — Users can produce product carbon footprints and Environmental Product Declarations compliant with recognised standards, outputting verified reports for internal and external use.

• Scenario Modelling & Eco-Design Support — The platform allows modelling alternative materials, processes or suppliers to compare environmental impact and identify lower-carbon design options.

• Data Quality Indicators & Transparency — Each footprint includes a Data Quality Rating (DQR) and a Primary Data Share (PDS) metric, indicating the reliability and origin (primary vs secondary) of the data used.

Closing Insights

According to the founders, Variable was developed to address pain points associated with traditional life cycle assessments: namely their high cost, static results and limited scalability across product portfolios. The platform shifts carbon footprinting from occasional consultancy-driven studies into continuous, operational workflows by combining background LCI data (e.g. from ecoinvent) with primary supplier and manufacturing data, all surfaced through API-driven integration and real-time supply-chain modeling.

Featured clients such as manufacturers in lighting and hardware use the platform across sustainability, R&D, procurement and sales functions to integrate footprint data into design and business decisions. Variable also supports compliance-grade outputs: verified PCFs and EPDs, based on standard methodologies (e.g. using the system model EN 15804+A2 for allocations and recycled materials).

For companies needing scalable, repeatable, audit-ready product-level carbon metrics, particularly those with large or complex portfolios, Variable offers a viable alternative to manual LCAs or one-off external studies. Its subscription model starts at €970/month for teams (covering 5 users, 2000 product elements and up to 100 suppliers) and scales to an Enterprise tier with ERP integrations and unlimited scope. By embedding LCA within existing workflows, and by providing data-quality indicators and integration flexibility, Variable positions itself as a tool for continuous footprint management rather than static assessments.
