The Sustainability Assessment Framework (SASF) is an initiative of the Global e-Sustainability Initiative (GeSI). It has been developed in cooperation with GeSI member-companies and external ICT experts. SASF allows the evaluation of the sustainability performance of ICT products and services.

SASF is a unique and comprehensive assessment framework. It enables ICT companies, from hardware manufacturers to service providers, to evaluate the sustainability performance of their products and services. The result is a product score, ranging from 0 points (lowest performance) to 100 points (highest performance).

The results allow very valuable insights into the value chain of products and services. We recommend using SASF as an internal management tool, as it allows users to manage their portfolios of sustainable products and services. Furthermore, SASF provides a solid foundation for policy/decision-making.

SASF is conceptualized and designed to be applicable to all major ICT products and services which comprise ICT hardware and/or data centres and/or networks. The application objective is to address the major sustainability impacts of the global ICT sector. Considering the diversity of current and future ICT products and services, it is possible that not all indicators are applicable to certain specific products/services, or do not cover all relevant sustainability impacts adequately (e.g. biodiversity).

All GeSI member companies are warmly invited to use SASF. More detailed information is available here:

No. All uploaded content is treated confidentially and cannot be seen by third parties. The results are only visible within the company account. See also Q14 on the website privacy and security settings.

Yes, a user manual is available in SASF under the ‘Home’ tab. In addition, webinars are offered in which users are encouraged to ask framework-related questions (see Q13).

SASF is available from June 2016.

The evaluation process depends on the level of availability of the information and resources within your company. Once the first product assessment is accomplished, part of the acquired information can be used for future assessments.

During the course of 2016, four webinars will be offered. Each webinar concludes with a Q&A session offering a unique opportunity to put framework-related questions to the project team.
