The Technology
We use the UK Department for Environment, Food and Rural Affairs emission factors — the global standard for transport carbon accounting. Factors cover road (0.1 kg/tonne-km), air (0.6), sea (0.01), and rail (0.028).
Every offset is backed by credits from Gold Standard and Verra VCS — the two most respected voluntary carbon registries in the world. No questionable offsets, ever.
Credits are permanently retired on-registry so they can never be resold or double-counted. Each retirement is traceable and auditable back to the specific project.
Join hundreds of e-commerce stores already offsetting their shipping emissions with Carbon-X.
