Tamsin S.

Sustainability and ESG Consultant

I’m Tamsin, a specialist ESG and Sustainability Consultant. I help businesses develop bespoke sustainability strategies that align with wider goals and priorities. My work enhances your business’s impact, improves reputation, and delivers benefits for both stakeholders and the planet. Sustainability is now essential to future proofing your business, not just ethically, but legally. With new regulations emerging rapidly, businesses are under increasing pressure to ensure their sustainability claims are credible and compliant. I stay on top of legislation like this so you don’t have to. I help businesses navigate change, avoid greenwashing risks, and meet expectations with confidence. I’ve worked with multiple businesses including dryrobe, Wanderlust Life and Nopinz to guide them through the B Impact Assessment and full certification process. Each business brings its own challenges, from tracking supply chain data to defining purpose and engaging teams. I offer clear, structured support as part of my B Corp consultancy, helping founders and teams understand the requirements, make meaningful improvements, and submit with confidence. Whether you're a values led startup or a more established brand looking to formalise what you're already doing, I’ll meet you where you’re at and take the pressure off.
