Note: Responsibility for the content of participants' public communication related to the Ten Principles of the UN Global Compact and their implementation lies with participants themselves and not with the UN Global Compact.
Note: We can redact your name, signature and any other personal information from your CoP. However, in alignment with our standard procedure, please note that we do not delete the online profile of a former participant, nor its letters of commitment and/or any other documents (including CoPs) that have been submitted voluntarily by participants as part of their engagement with our initiative. Transparency and disclosure are core values to which participants adhere when joining the UN Global Compact, and we continue to uphold these values by ensuring a transparent record of our current and past participants on our public database. Please see our CoP Removal Request Policy for more information.
Note on levels: Not applicable refers to the period when the Communication on Progress (CoP) did not require differentiation levels. With the new CoP , for the 2022 Early Adopter Programme, and for 2023, there will be no differentiation levels.
