What Institute of Environmental Management & Assessment does

The Institute of Environmental Management & Assessment (operating as ISEP, the Institute of Sustainability and Environmental Professionals) is a UK-based non-profit professional membership body serving environmental and sustainability practitioners. It is a company limited by guarantee headquartered in March, Cambridgeshire, with 101-250 employees and led by CEO Sarah Mukherjee MBE. The organization operates under the dual web presence of iema.net and isepglobal.org and recently rebranded from the IEMA name to ISEP to reflect a broader sustainability mandate.

The Institute's core offering is a chartered-membership pathway that includes a Foundation Certificate, Practitioner and Chartered credentials, and a continuing professional development regime. It publishes tools that codify its standards, including the GHG Management Hierarchy (recognized by the UNFCCC and ISO), the Skills Gap Tool, and the Sustainability Skills Map. Knowledge dissemination is delivered through the ISEP Connect conference, the Transform magazine, the Sustainable Matters podcast, and a Jobs Board. A 2026-launched retail shop adds a consumer and corporate merchandise channel. Revenue mechanics are diversified across individual membership subscriptions (recurring), training and accreditation fees routed through Training Partners, conference and event sponsorships, corporate partnerships, job-board advertising, and shop sales, supported by University and Affinity Partner programmes that feed the talent pipeline.
