UK: The UK Green Building Council ( UKGBC ) has confirmed Simon McWhirter as its new chief executive. 

McWhirter, who previously served as deputy chief executive, will take on the role of chief executive following Smith Mordak concluding their two-year tenure in the role.

With a background spanning sustainability advocacy, communications, finance, political engagement, and property development, McWhirter played a pivotal role in leading UKGBC’s policy, public affairs, and member engagement strategies, nationally and internationally.

Judith Everett, chair of UKGBC said: “Simon brings strong relationships across the built environment sector, government and our partners, attuned to the nature and climate crises we face.

“His sector experience across domestic and international networks, and – supported by UKGBC’s passionate and capable team – makes him well-placed to lead this next phase. 

“As well as knowing the sector well, he has been involved with UKGBC from its inception 18 years ago – most recently leading our political, communications, membership and international work. The Trustees felt he was the right person to lead the organisation.”

The Board of Trustees also commented on Smith Mordak’s contribution saying they had “brought a wealth of industry knowledge, deep technical expertise, first-hand insights of creating sustainable places, and as a passionate campaigner for action on the environmental crises and to engender an equitable society.

“We have valued the expertise and energy that they have brought to the UKGBC as the organisation continues to evolve. We would like to take this opportunity to wish them all the very best for their future endeavours.”

Simon McWhirter, new chief executive said: “With the current backdrop of political and economic upheaval, UKGBC is exceptionally well positioned to help bring clarity, certainty and a wealth of positive solutions for decision-makers across government and industry – about how we design, deliver and indeed revel in buildings and places that are not just radically more sustainable – but radically better places to live, work and play.

“I want to express my thanks to Smith for their sterling work over the past couple of years, and the support for me over that time; and their leadership helped set the stage for me and the team to really shift the dial about how we can really use the UK’s built environment as a positive lever for change in combating the climate and nature crises.”
