Hirigoyen joined UKGBC as chief executive in 2015, and has since been credited with transforming its strategy into a more member-focused, holistic sustainability agenda with a strong focus on impact measurement. At the helm of a fantastic team, Hirigoyen and UKGBC have some important achievements to celebrate – including galvanising industry support for a net zero carbon legislative target in 2019, convening industry consensus around definitions of net zero carbon buildings and circular construction, and influencing government policy at both national and local levels on a range of impact areas including net zero carbon, biodiversity net gain, climate resilience, and waste and resources strategy amongst others. Her own purpose is to support and empower her team to drive effective change, and to act as UKGBC’s spokesperson with the media, members, regulators, and wider stakeholders, as well as forging links with other GBCs across the world. She was previously UK head of sustainability and an international director at JLL.
