How is this calculated?

Carbon footprint comparison between an eco mailer box, a premium mailer box and a benchmark product.

~50-90% smaller carbon footprint than a premium mailer box

~16-56% CO2e

Transport

Manufacturing our eco mailer boxes in the UK instead of overseas can reduce their carbon footprint by up to 56% (depending on freight type) compared to premium mailer boxes, with savings increasing for larger orders.

~16% CO2e

Materials and secondary packaging

Digital printing allows our manufacturers to use thinner paper liners. This reduces material usage of the paper liners by c.40%, which translates to an average 16% emissions reduction.

~18% CO2e

Manufacturing

Eco mailer boxes produce less waste during setup and need fewer tooling plates than premium mailer boxes. With less waste, materials and energy used, you can reduce your carbon footprint by 18%.

Supply chain

A resilient, responsible supply chain

Certifications

We validate all supplier claims and third-party certifications such as ISO, BRC and FSC. And we ensure suppliers adhere to UK and EU laws on chemicals and product components, like UK REACH. This allows businesses to confidently buy high-quality products that align with a net-zero trajectory.

Our mailer boxes are certified FSC Mix.

Vetted suppliers

We visit and vet every supplier we work with. We use our code of conduct to do this, which defines what we consider to be ethical working conditions. To work with Sourceful, suppliers and their manufacturing sites must meet this code. We then review their practices every year.

Quality control

Every order from our suppliers undergoes a quality inspection process before it’s shipped. Any order that fails quality inspection is returned to the manufacturer or reproduced.

For orders manufactured internationally (outside the UK), we follow the Acceptable Quality Limit (AQL) method defined by ISO 2859 - 1.

For orders manufactured domestically (inside the UK), our suppliers perform the quality inspection process which we then verify through spot checks throughout the year.
