Having joined CIEH in 2016, Ms Godfrey delivered a significant change programme to restore financial stability, refocus on membership and the profession and ensure a sustainable future.
She is leaving CIEH to join GS1 UK as its new chief executive and will take up her post in August.
Siraj Choudhury, chair of the CIEH Board of Trustees, said: “The comprehensive transformation of CIEH under Anne’s leadership has been remarkable. The organisation was in a financially precarious position when Anne joined us.
“As a result of her inspirational leadership, we have been able to take staff and members with us through our evolution. Anne leaves CIEH in a far stronger position.”
Ms Godfrey said the last four years had been both challenging and rewarding and that she was sad to be leaving.
She added: “Environmental health is of vital importance to our country and our world, and I am honoured to have worked with so many people who make such a positive contribution to our society.”
