Our Considerations For Choosing These Eco-Friendly Tea Brands

What is sustainable tea, exactly?

In a (sustainably grown) nutshell, it’s tea grown, harvested, processed, and packaged in a way that’s better for people and the planet. 

Here’s what we looked for. 


We like green tea but don’t like greenwashing, so as always, third-party certifications are key.

A Plastic Planet, B Corporation, Carbon Neutral, Rainforest Alliance, Fairtrade, Fair For Life, FairWild, Green-e, Living Wage Foundation, Soil Association, USDA Organic, Vegan Society. 


Sustainably grown, ideally certified organic tea leaves make for the most eco-friendly cuppa, but we know certification isn’t always possible for small producers. 

Other ingredients included in blends, like fruit, herbs, and spices, should meet the same criteria. 


We looked for brands committed to creating a positive impact by putting the planet and people first. 


Choosing loose leaf tea minimizes tea packaging and the extra resources for making tea bags. 

If you can, pop down to your local zero waste store with a reusable container. Otherwise, opt for recyclable and backyard compostable packaging. 

If you want the convenience of a tea bag, look for plastic-free tea bags that are compostable with outer packaging that is compostable and/or recyclable. 

Ethical Sourcing: 

Traceability is key. We’re pleased to see the brands on this list building long-term relationships with tea growers and ensuring they receive a fair price for their tea. 


Whether supporting regenerative farming practices, using renewable energy, carbon offsetting, tree planting, or donating to reforestation programs, brands can curb their carbon footprint in many ways. 

Paying It Forward:

Big-hearted tea brands that go the extra mile to support tea farming communities or donate to local and global causes are definitely our cup of tea. 

Closing Thoughts On Sustainable & Fair Trade Teas

Tea is the most widely consumed drink after water. 

But is tea sustainable? 

These ethical and eco-friendly tea companies demonstrate that it can be, through responsible sourcing and taking steps to reduce the environmental impact of processing, packaging, and shipping.
