The member portal keeps the register; certificates issue per activity, ready for employer or regulator.
The Professional Standards committee audits a random sample of records every year.
40+ hours a year for three consecutive years earns the Certified Member distinction — CMESK.

Before you ask
Membership, answered
No. The register spans lawyers, engineers, planners, EIA and audit practitioners, climatologists, communicators, financiers and educators. If the environment is your profession — in practice, study or mandate — there is a grade for you.
Fees are annual from admission, with a sixty-day grace window. Students at partner institutions and members in hardship may apply to the Chapters committee for a waiver. No one is removed from the register for inability to pay alone.
Yes — at Professional grade or above, on an affiliate basis. Our mandate is Kenyan; our members are not exclusively so.
Any time. Upgrades follow the same committee review, and your accumulated CPD record counts toward eligibility.
No. The record, hour certification and the Certified Member distinction are all included in membership.
Corporate and institutional subscriptions are generally treated as professional subscriptions. The Secretariat provides the documentation your finance team needs — confirm treatment with your own advisors.
