Josephine Billany

Josephine is a sustainability consultant with expertise in B Corp Certification, Impact Reporting, and developing sustainability strategies through double materiality assessments. She has worked with clients of all sizes across sectors, including finance, fashion, and food and beverages.

With a First Class BSc in Biological Science from Cardiff University, Jo combines a scientific approach with clear, engaging communication—producing compelling reports, creating practical tools, and analysing both qualitative and quantitative data.

At Junxion, she leads internal impact management, overseeing carbon footprint measurement, annual impact reporting, B Corp recertifications, and the development of Junxion’s Impact Strategy. She is passionate about Justice, Equity, Diversity and Inclusion, and volunteers with the Diverse Sustainability Initiative to help build a profession that reflects modern Britain.

Jo is also a trained Climate Fresk facilitator, running interactive workshops that help people understand the causes of climate change and explore solutions. Outside of work, she enjoys London’s cultural scene—gigs, theatre, cinema, and pubs—and often returns to the countryside where she grew up for a dose of nature.
