Lucy Siegle - Speaker

Lucy Siegle is a journalist, broadcaster, and sustainability advocate specialising in climate, nature, and the environmental impact of consumerism. As a presenter on BBC One’s The One Show and co-executive producer of the Netflix documentary The True Cost, Lucy has built a reputation for making ecological issues more accessible and encouraging action. Her focus includes the environmental and social footprint of the global fashion industry and the widespread problem of single-use plastics.
Lucy’s interest in sustainability developed through years of reporting on the challenges posed by fast fashion, plastic pollution, and corporate greenwashing. Her book To Die For: Is Fashion Wearing Out the World? served as the foundation for The True Cost, a documentary that exposed the social and environmental consequences of the fashion industry. This work established Lucy as an advocate for ethical fashion and responsible consumer choices.
Throughout her career, Lucy has highlighted the need for industries to address their environmental impact, often challenging the narratives of major fashion brands. As a co-founder of the Green Carpet Challenge with Livia Firth, Lucy has also worked to promote sustainable fashion at high-profile events such as the Oscars and Met Ball.
