Why sustainability matters for young people
Climate change, plastic pollution, food waste, fast fashion – these are not abstract problems for young people. They are the defining challenges of their generation. But here is the good news: solving them creates incredible business opportunities. Every product that replaces plastic, every app that reduces waste, every service that extends the life of clothing is also a viable, fundable, scalable business.
The founders featured in this article did not wait for permission. Tessa Clarke built Olio because she could not bear to throw away leftover food when moving house. Laura Harnett created Seep after discovering that kitchen sponges shed harmful microplastics. Ruby Raut designed WUKA because her mother in Nepal had nothing but sari rags. Each one spotted a real-world problem and built a solution.

Of young people say climate action influences their career choices
The UK has committed to reaching net zero by 2050, and the transition is creating entirely new industries. Renewable energy, sustainable fashion, green construction, electric vehicles, and circular economy services are all growing rapidly. The Green Finance Institute estimates that trillions of pounds of investment are needed – and that means jobs, businesses, and opportunities for anyone willing to think differently about how we live.
Benefits of building a sustainable business
Purpose-driven work
Sustainable businesses solve real environmental problems. Whether it is reducing food waste, replacing single-use plastic, or making fashion circular, founders in this space know their work makes a tangible difference to the planet and to people's lives.
Growing demand
Consumer demand for sustainable products is rising year on year. Research by Deloitte shows that over a third of UK consumers now actively choose brands based on environmental credentials. For young founders, this means a ready and growing market.
Innovation at the core
Sustainability forces creative thinking. How do you make cleaning products without plastic? How do you build a profitable food-sharing platform? The constraints of sustainability drive some of the most innovative and original business models in the UK today.
Future-proof career skills
Green skills are in demand across every sector. Whether young people go on to start a business or enter employment, understanding sustainability, circular design, and environmental impact gives them a competitive advantage in the job market for decades to come.
Challenges young people face in sustainability
Greenwashing makes it harder for genuine eco businesses to stand out. Young people need to understand what real sustainability looks like – and these founders show exactly that, with B Corp certifications, transparent supply chains, and measurable environmental impact.
The complexity gap
Sustainability can feel overwhelming. Climate science, supply chains, carbon footprints, lifecycle analysis – the language alone can be off-putting. The founders featured here prove you do not need a PhD to make a difference. Tessa Clarke started Olio by sharing food with her neighbours on WhatsApp. Charlotte Liebling began Loved Before by rescuing teddies from charity shop bins.
The funding challenge
Green businesses sometimes face scepticism from investors who question whether sustainability and profit can coexist. Every founder in this article has proven they can. Olio has raised over £50 million. Good Energy powered 250,000 homes. WUKA won a Queen's Award. The business case for sustainability is now well established.
The knowledge gap
Many young people care deeply about the environment but do not know how to turn that passion into a career or business. Schools rarely connect environmental awareness with entrepreneurship. That is where platforms like We Can Be come in – helping young people see that the skills they learn in enterprise education are the same skills they need to build green businesses.

These founders prove that circular business models can be profitable, scalable, and genuinely impactful.
