The Problem
Global e-commerce shipping produces over 100 million tonnes of CO₂ annually — and it's accelerating with next-day delivery expectations.
Most online stores have no way to calculate the carbon footprint of each shipment, making sustainability claims impossible to back up.
73% of consumers say they would change their buying habits to reduce environmental impact. Sustainability is no longer optional.
How It Works
A customer checks out on your store — business as usual. The Carbon-X widget loads automatically.
Carbon-X calculates the exact CO₂ footprint of the shipment using DEFRA-verified emission factors in real time.
The customer sees the offset cost and ticks a checkbox to fund verified carbon credits through Gold Standard and Verra projects.
