From IEMA to ISEP: What the Name Change and Rebrand Means for You

We’d like to thank all our customers who’ve reached out with questions regarding the rebrand of IEMA, Institute of Environmental Management and Assessment, to ISEP, The Institute of Sustainability and Environmental Professionals.

IEMA, the Institute of Environmental Management and Assessment, has served as the leading global professional body for environmental sustainability practitioners for over 25 years. With more than 22,000 members in 125 countries, they’ve long championed the sector. But as the sustainability profession has evolved, so too has IEMA’s remit.

Acknowledging that their original name no longer fully reflected the breadth of their work, IEMA engaged in a thorough consultation process involving surveys, focus groups, and workshops with members. The outcome? A proposed new name: The Institute of Sustainability and Environmental Professionals, ISEP. In December 2024, members voted overwhelmingly in favour of the change, paving the way for a rebrand that includes a refreshed logo and a modernised visual identity. This evolution better aligns with their expanded focus on sustainability skills and support for professionals across the green economy.

Naturally, changes like this bring up some important questions. While some details are still being confirmed, we’re in close contact with IEMA and will continue to provide updates as they become available.

When Will the ISEP Rebrand Be Made Public?

The ISEP brand was officially launched to the public on 17 July 2025.

Will This Affect My Post-Nominals (AIEMA, PIEMA)?

Yes. Members will transition to new post-nominals aligned with the ISEP brand starting 17 July:

• AISEP – Associate
• PISEP – Practitioner
• MISEP – Full Member

These replace the former AIEMA, PIEMA, and MIEMA designations.

Are IEMA Training Course Titles Changing?

Yes, slightly. Course titles are updated to reflect the new ISEP branding, though the content remains unchanged. For courses completed following the public rebrand, your certificate will be eligible for the new title. For example:

• IEMA Foundation Certificate in Environmental Management (AIEMA) → ISEP Foundation Certificate in Sustainability & Environmental Management (AISEP)
• IEMA Certificate in Environmental Management (PIEMA) → ISEP Certificate in Sustainability & Environmental Management (PISEP)

Is My Existing IEMA Certificate Still Valid?

Yes. While there hasn’t been a formal statement, our conversations with IEMA confirm that all existing certificates issued under the IEMA name remain valid.

When Will New Certificates Display the ISEP Branding?

Certificates issued for courses completed on or after 8 January 2025, when IEMA legally changed its name to ISEP, will bear the ISEP branding.

Certificates for training completed before that date will retain the IEMA name, as ISEP was not yet a legal entity.

Didn’t the ISEP Name Change Already Happen in January?

Yes, the legal name change took effect on 8 January 2025, and ISEP has since been using the new name with partners, banks and suppliers. However, the wider public rebrand rollout officially took place on 17 July 2025.
