Green web hosting: what's real and what's greenwashing
Most 'green hosting' claims are carbon offsets. Here's how to find hosts that actually run on renewables — and whether it matters for your site.
What green hosting usually means
The most common claim is 'carbon-neutral' via offset purchases — buying credits that fund tree planting or renewables elsewhere. That's better than nothing but it's not running on renewables.
True green hosting means data centers powered by on-site or directly-purchased renewable energy. A small number of hosts can credibly claim this.
Hosts with real renewable infrastructure
GreenGeeks (300% renewable matching via wind credits), Krystal (UK, 100% renewable grid), and major cloud providers in select regions — Google Cloud claims 24/7 carbon-free in some regions, AWS in some EU regions.
Check the Green Web Foundation's database — they verify claims against real grid data.
Does it matter for your site
Climatically, an individual website's footprint is tiny. The case for green hosting is more about market signal — telling hosts that customers care creates pressure across the industry.
If two hosts perform similarly, pick the greener one. Don't compromise on performance or support for it — a slow green site that drives users to faster competitors isn't actually a climate win.
