How we rank

Hosts verified green by the Green Web Foundation come first, ordered by how clean the electricity grid is where their data centres are, cleanest first; the other hosts follow in the same order.

"Verified green" means the host is in the Green Web Foundation's directory of verified green providers. Until October 2026 the Foundation accepted carbon offsets as evidence; it no longer does, and it checks hosts verified before then against the new rules when they next renew. How the Foundation verifies hosts.

The grid figure is the average carbon intensity of the electricity grids in the countries where a host has data centres: the grid around the data centres, not the energy the host itself buys. The bar shows it on one scale from 0 to 400 g. The mark on each bar is the UK grid, 218 g per kWh. Grid figures: Ember, Yearly electricity data (2026), CC BY 4.0.

The hosts we list are our judgement of good hosts: being green is one factor, and price, reliability, support and privacy matter too, which is why we say what each host is good for. Payment never changes our advice. The order follows the ranking rule above.

Listing data from the Green Web Foundation's Green Web Dataset, made available under the Open Database License (ODbL). How we matched our hosts to it: green-web-foundation.csv, under the same licence.
