Bluehost vs SiteGround: green hosting compared
Bluehost and SiteGround side by side: each one's Green Web Foundation listing, where its data centres are and how carbon-intensive those grids are, and the evidence it publishes. They are in alphabetical order: no host pays for its place.
The difference
Only SiteGround is listed in the Green Web Foundation's directory of verified green providers; we found no matching entry for Bluehost.
Neither host's listed countries all have lower-carbon grids than the other's. Across both, their countries' grid averages run from 41 gCO2e/kWh in France (2025) to 671 gCO2e/kWh in India (2025), so which grid your site runs on depends on the region you choose.
These are the facts we can show, not a verdict on which is greener: the listing, the grids and each company's own claims measure different things, and none of them measures your website. Each host's full page has every quote and source.
Each dot is a country where the host lists data centres, placed by that country's grid average. Bluehost, no matching entry in the Green Web Foundation's directory: 9 countries, from 41 gCO2e/kWh in France to 671 in India. SiteGround, listed in the Green Web Foundation's directory: 8 countries, from 41 gCO2e/kWh in France to 518 in Australia.
