Ecommerce deliveries have a carbon footprint. That's why we support verified projects that remove carbon from the air.
Every delivery’s carbon footprint is calculated based on weight, shipping method, and distance traveled. We neutralize these emissions by purchasing verified carbon removal credits from groundbreaking projects.

We work with a network of pioneering carbon removal companies that have been vetted by the commerce platform Shopify.
