Making Sustainability Accessible for SMEs

We believe every business — no matter its size — has a role to play in tackling climate change. Bright Sustainability exists to make that journey practical, affordable, and achievable.

Our Mission

To equip UK small and medium-sized businesses with the knowledge, tools, and support they need to reduce their carbon footprint, build climate resilience, and thrive in a low-carbon economy.

Will Marshall — Founder of Bright Sustainability

Will Marshall

Founder & Lead Trainer — MEng (Hons), MIET

Having worked in corporate, SME, and early-stage start-up environments, Will founded Bright Sustainability with a clear mission: to provide businesses with real, actionable, value-added sustainability services. He believes sustainability shouldn't be the preserve of large corporations with dedicated teams and big budgets — SMEs make up 99% of UK businesses and have an enormous collective potential to drive change.

After studying Electrical Engineering and New and Renewable Energy Engineering, Will worked in the infrastructure industry in a variety of management roles before moving into the world of SMEs. This combination of technical rigour and first-hand SME experience means he understands the real-world constraints smaller businesses face — tight budgets, limited time, and competing priorities.

As an accredited Carbon Literacy trainer, Will has delivered training to hundreds of professionals across Greater Manchester and beyond, helping them understand climate change and take practical action in their workplaces and daily lives.

Will also founded Emitrics, an AI-driven carbon accounting platform currently on the Exchange tech accelerator, making carbon measurement simple and accessible for businesses of all sizes.
