tell.üs™ Data Vault is a secure, cloud-based repository that collects, verifies, and standardizes environmental and supply chain data—right down to Tier 4. Suppliers and customers can upload data directly, which is then validated and made available for download in any format to integrate seamlessly with your existing ESG, procurement, and reporting systems. Tellus ensures you have accurate, auditable Scope 3 data for compliance, decarbonization, and decision-making—eliminating gaps, guesswork, and duplication.

STERA™ (Scope Three Environmental Reporting Application) is a powerful, all-in-one platform for organizations without existing ESG or procurement software. It provides unprecedented visibility into your extended supply chain—delivering actionable insights, verified emissions data, and supplier intelligence down to Tier 4. Built for clarity, compliance, and climate impact, STERA makes advanced Scope 3 reporting possible—without the complexity.
