The Sustainability Data Exchange Project (SDEX) was developed collaboratively between the European Outdoor Group (EOG) and the Bundesverband der Deutschen Sportartikel-Industrie (BSI) and was launched in July 2023.

SDEX Project

The SDEX Project is an industry initiative to enable consistent, efficient, and interoperable exchange of sustainability data across the value chain. This project was developed through collaboration between over 25 brands and retailers to address the growing number of overlapping and duplicative product-level sustainability data requests made by retailers to brands.

SDEX Standard

The SDEX Standard is a defined framework of agreed data points, structures, and definitions for exchanging sustainability information between Brands and Retailers.

The standard was developed in response to existing retailer questionnaires and evolving European policy requirements, identifying areas of overlap and duplication. It establishes a harmonized data structure to support consistent, comparable, and verifiable product and brand-level sustainability information.

By aligning data requests within a shared framework, the SDEX Standard aims to reduce administrative burden, improve data quality, and strengthen information readiness across the value chain.

The SDEX Tool is the free Excel-based implementation of the SDEX Standard, designed to support data collection and exchange. In September 2025, the latest version of the SDEX Standard, SDEX 3.0 launched. For access to the Excel sheet, please click here.

SDEX Digital Platform

The SDEX Digital Platform will be a central, independent digital repository for securely hosting and sharing brand and product sustainability data in line with the SDEX Standard. This new iteration, SDEX 4.0, is coming soon.
