Our latest Shops That Matter feature explores one of the UK’s quiet sustainability success stories — Riverford Organic Farmers. What started as a small Devon farm has grown into a national organic veg-box service that’s changing how food reaches our tables. Every carrot, cabbage, and leek comes from farms that work with nature, not against it. But the real story isn’t just the vegetables — it’s the ownership. Riverford is fully employee-owned, meaning profits and decisions are shared among the people who grow, pack, and deliver the food. It’s proof that fair pay, happy teams, and environmental care can thrive together. Inside the lesson, we explore:🌾 How employee ownership reshapes business ethics.🥕 How planning ahead reduces waste and stabilises farmer incomes.📦 How the veg-box model builds a loyal community of conscious eaters.🌍 And what other organisations can learn from their success. 🪴 Explore it now under Shops That Matter → Riverford: Employee-Owned and Earth-Aligned💬 Join the conversation: What part of Riverford’s model could work in your local community? Let’s celebrate — and learn from — businesses proving that sustainability can scale. 👉 Find it here.

We’ve just opened a new section inside Has2BGreen called Shops That Matter — a growing collection of real-world examples showing how business can heal the planet, not harm it. Each entry is a mini-lesson exploring a company or organisation that’s making a difference — from regenerative farms and zero-waste brands to fair-trade networks and circular design innovators. We start with CrowdFarming: Regenerative by Design, a European platform helping farmers sell directly to consumers while rebuilding soil health and restoring ecosystems. These stories aren’t ads. They’re models to learn from — showing how fairer economics, better design, and environmental care can work together. 🪴 Explore the new section under “Shops That Matter”💬 Share your finds: Know a business worth featuring?

That’s why projects like The Ocean Cleanup’s Interceptor matter. They’re cutting pollution at the source before it ever reaches the sea. These guys have to be one of my favourite organisations. I love how they’re going about it, just steady progress and real impact. They’ve had their ups and downs, but they kept building. Massive respect. They’re doing incredible work. 💙 💧 Learn more here: The Ocean Cleanup
