The following members of the B4NZ team are experienced public speakers. If you are interested in having them speak at your event, please get in touch with francesca.oneill@b4nz.co.uk.

Heather Buchanan

Heather is the CEO and Co-Founder of B4NZ, where she leads ground-breaking work at the intersection of finance, sustainability, and policy. A trusted advisor to Government, industry bodies, and civil society, she brings deep expertise in reshaping the commercial relationship between banks and their customers to better serve the real economy.

Since COP26, Heather has been a driving force behind the financial sector’s role in delivering a just transition, culminating in B4NZ’s prominent role as a core partner of the UK Pavilion at COP28. Under her leadership, B4NZ has grown to become widely respected in the UK and has since expanded its global reach – delivering innovative finance solutions in the UAE and Bolivia that leverage the UK’s leadership in financial services and its role in international efforts such as the Glasgow Financial Alliance for Net Zero (GFANZ). This international work supports green growth in emerging markets and reinforces the UK’s global influence in sustainable finance.

In recognition of her impact, Heather was named one of Reuters’ Trailblazing Women in Climate and shortlisted as Sustainability Leader of the Year by Business Green in 2024. She is currently a finalist for Leader of the Year in the 2025 Business Green Awards.
