About

Hi, I’m Demi. I aim to be a trusted partner that simplifies sustainability. As the founder of Hearth Sustainability, a certified B Corp, and an award-winning sustainability consultant, I draw on years of experience to offer tailored strategies and actionable steps to guide organisations on their unique sustainability journeys. I also co-chair B Local Brighton and co-founded Sussex Impact Pathway, a collaborative programme supporting groups of businesses through the B Corp assessment.

Based in Brighton, I work with SMEs across Sussex and the UK, offering sustainability consultancy and B Corp certification support. The two key barriers for businesses wanting to become more sustainable are time and money. My consultancy eliminates these by streamlining processes, making sustainability strategy and ESG improvement more efficient, affordable and accessible for small businesses.

At the heart of my project management career lies a deep commitment to sustainability. I’ve been an embedded Sustainability Manager and Consultant, leading 30+ businesses through B Corp certification and creating sustainability strategies across both service and manufacturing industries.

From founding a capital city arts festival focused on ESG principles to wearing multiple hats at the National Museum of New Zealand, my journey reflects a passion for meaningful change and a dedication to our planet.

Fuelled by witnessing our world’s beauty, the transformative power of climate marches and social justice movements, and the strength of the B Corp community, I believe sustainability consultancy goes beyond meeting standards. It’s about driving genuine change at the intersection of social justice and environmental regeneration.

With a diverse background and a deep-rooted passion for sustainability, I’m here to help your business thrive while making a positive impact on people and planet.
