We are sharing an important update: The Sustainability Consortium (TSC) and Sphera Solutions, Inc. (Sphera) will be discontinuing the THESIS program. There will be no THESIS campaign in 2026, and the THESIS platform will be retired as of September 1, 2026. 

It is important to note that no other Sphera subscription, functionality or data hosted on Sphera’s own Supplier Engagement portal will be affected by the sunsetting of THESIS and this change only relates to the THESIS platform. 

We are proud of the impact THESIS has delivered helping to align sustainability expectations across retailers and brands, reducing reporting friction, and driving measurable improvements across global supply chains. Looking ahead, both Sphera and TSC are each focusing on expanding the impacts of their respective research, insights, and offerings in new ways. Each is actively exploring opportunities to ensure their respective work continues to support companies as they address complex sustainability challenges.

If you have an active THESIS account, your company’s main account holder received email instructions from Sphera to download your data.  If you need support accessing your THESIS account, downloading your data, or have questions about other Sphera subscriptions please contact Sphera Customer Care: https://sphera.com/customer-care/.

If you would like to learn more about TSC’s upcoming programs or membership opportunities or have questions about THESIS content, please reach out to [email protected]. If you would like to learn more about Sphera’s Supply Chain Sustainability Platform, please reach out to [email protected]. 

Thank you again for your partnership with Sphera and TSC, and for the role you’ve played in advancing sustainability through THESIS. We look forward to continuing working together in the future.

Sincerely,

Your TSC Team
