A B-Corp since December 2023, Good & Proper Tea is committed to "doing things properly," minimizing environmental footprint, and maximizing social impact. They embed sustainability in daily decisions, meticulously scrutinizing their supply chain from cultivation to warehouse. Responsible sourcing includes paying producers above Fairtrade standards and building direct relationships, as seen with Malawian smallholders.

Their commitment extends to packaging and operations. They use 100% plastic-free, compostable tea bags and Natureflex (from renewable wood pulp) for inner bags; loose leaf packaging is also plastic-free. All orders ship from their SE London warehouse, powered by renewable energy. They uphold high reuse and recycling standards, including the "Forgive me, I’m an ugly box" initiative. Good & Proper Tea aims to drive industry change through continuous improvement and knowledge sharing.
