Along the way they have been active in significant industry initiatives to achieve an equitable and lasting transformation of the built environment to a sustainable and regenerative model.
“I would also like, on behalf of the board of trustees, to give heartfelt thanks to Julie Hirigoyen for her eight amazing years as CEO. She has been an outstanding leader, growing consensus around the urgent need for action on the climate and biodiversity crises, building a highly effective and networked organisation equal to its critical mission, as well as steering UKGBC adeptly through times of global crisis. We wish Julie every success in her future endeavours.”
Mordak said: “I’m thrilled to have this opportunity to work with the amazing team, trustees, and membership at UKGBC. I’m looking forward to building on the charity’s extraordinary body of work and Julie’s inimitable legacy. We live in existentially challenging times. Our actions over the next few years will have an outsized impact on the earth’s ecosystems and on many generations to come. I’m honoured that I’ll be playing my part in this crucial period as part of this powerful, change-making coalition.”
