Completing the Supplier to Zero Level 1 is necessary in order to get access to Level 2.

However, when your Supplier to Zero Level 1 or Level 2 certificate has expired, you can renew your highest certificate directly.

Note: Please make sure you complete your submission in time!

Effective June 2023, some of the terminology is changed to align with the 2030 Impact Strategy. Certification levels within Supplier to Zero for non-signatory suppliers terminology has changed from Foundational, Progressive, and Aspirational Level to Supplier to Zero Levels 1, 2, and 3.

For more information regarding the updated terminology, please refer to the following Knowledge-Base article: New Terminology.
