From that moment, ISEP will officially become The Institute of Sustainability and Environmental Professionals (ISEP).
This transformation marks more than just a name change. It’s a bold step into the future of our profession – one that recognises the crucial role of environmental and sustainability professionals at the heart of the global economy.
Since our founding more than 25 years ago, our work has evolved from the periphery of business and policy to a driving force for sustainable change. Our new name and purpose reflect this shift and set the stage for the future.
As part of the rebrand, we’re introducing a new set of professional membership suffixes that align with our updated identity. From the public launch in mid-July, members can begin using the following postnominals:
Chartered Environmentalist (CEnv) and Registered Environmental Practitioner (REnvP) designations will remain unchanged. A potential suffix for retired members is under discussion and will be reviewed at our next board meeting.
To support your transition, new digital membership credentials will be issued during the launch week. These will feature your updated suffix and can be used in email signatures and on LinkedIn and other professional platforms. Make sure your email address is up to date so you receive your personalised credentials.
The rebrand isn’t just a change in name – it’s a shared movement driven by thousands of professionals like you. Every member will receive an amplification pack by email in July, filled with tools to help you share the news with your networks, colleagues and employers. From social media assets to email banners, the pack will empower you to help shape awareness of our new identity across the profession and beyond.
The rebrand is the culmination of the Future Purpose of ISEP project, a wide-reaching, member-led process launched nearly three years ago. More than 6,400 member engagements, including surveys, workshops and interviews, shaped the journey. A resounding 81.19% of members voted in favour of the change at our extraordinary general meeting in December 2024. The outcome was clear: a fresh identity for a dynamic profession.
ISEP’s purpose is to empower our members to become global changemakers, transforming the world today for a sustainable future. Whether you’re an environmental specialist, a sustainability generalist, or someone simply driving positive change in your area, ISEP is here to inspire you with ideas, enable you with best practice and ensure your excellence with globally recognised standards.
From 17 July 2025, you’ll start to see the new ISEP name, logo and identity across our website, training materials, certificates, reports and social media. You’ll also receive your updated digital membership certificate and LinkedIn badge to help showcase your professional commitment. Until then, please continue using ‘ISEP’ in day-to-day professional settings.
We’re very grateful for the support, insight and participation of our members throughout this journey. The new brand belongs to all of us – and with your voice and advocacy, we can ensure that ISEP reflects the strength, clarity and future ambition of our global profession. Let’s shape the future, together.
