The 7 best green web hosting providers in 2026:
The hosting industry has a greenwashing problem. Search for "green web hosting" and you will find dozens of providers claiming eco-friendly credentials — some legitimate, others based on nothing more than buying cheap offsets that fund projects of dubious quality.
This guide cuts through the noise. Every provider listed here has verifiable renewable energy documentation, a published PUE (Power Usage Effectiveness) score, or a listing on the Green Web Foundation's verified directory. The data below was collected in Q1 2026.
If you want to check whether your current host is genuinely green, use our website carbon badge tool — it cross-references the Green Web Foundation API and calculates your site's estimated emissions per page view.
According to the Sustainable Web Design Model v4, a single page view's carbon footprint breaks down across three segments: data center (28%), network transfer (31%), and end-user device (41%). Switching to a verified green host reduces the data center segment by roughly 75%, cutting your total footprint by about 21% per page view.
That might sound modest. But scale matters. A site with 500,000 monthly page views on conventional hosting emits roughly 1,440 kg of CO2 per year. On a verified green host, that drops to approximately 1,138 kg — a 302 kg reduction. That is the equivalent of planting 14 trees annually, just from a hosting switch that costs the same or less than what you pay today.
The data center's share matters even more when you factor in PUE. A provider with a PUE of 1.6 (the industry average) wastes 60% of its incoming electricity before it reaches the servers. A provider with a PUE of 1.1 wastes only 10%. The combination of renewable energy sourcing and efficient facility design is what separates genuinely green hosts from those that merely pay for offsets.
Each provider on this list was assessed against four criteria:
Providers that rely solely on carbon offsets without renewable energy sourcing were excluded. "Carbon neutral" claims backed only by cheap avoidance offsets are not green hosting — they are accounting exercises.
Infomaniak is the most credible green host on this list, full stop. Based in Geneva, Switzerland, the company runs its data centers on 100% Swiss hydroelectric and solar power. Critically, it is not purchasing RECs from across Europe — the renewable electricity is directly contracted from local Swiss producers. Its PUE of 1.08 ranks among the best in the industry globally, outperforming Google and Microsoft.
Infomaniak publishes an annual sustainability report with third-party audited emissions data. It is listed on the Green Web Foundation's verified directory and holds the ISO 14001 environmental management certification. Shared hosting plans start at around €5.75/month; Swiss data center location means GDPR compliance is structurally guaranteed.
The one limitation: their infrastructure is primarily Europe-focused. If your audience is predominantly North American or Asian, latency may be a consideration.
Google has matched 100% of its global electricity consumption with renewable energy every year since 2017. Its goal is more ambitious than that: achieving 24/7 carbon-free energy by 2030, meaning every hour of computing is matched with carbon-free electricity from the same grid region. This is a fundamentally different (and harder) commitment than annual matching.
Its fleet-average PUE of 1.10 is exceptional for infrastructure of this scale. Google's data centers in Finland, Denmark, and Iowa operate on particularly clean grids; its Singapore and Taiwan facilities lag due to regional grid constraints. The Carbon Footprint dashboard in Google Cloud Console provides per-project emissions estimates, making it the most transparent major cloud provider for carbon accounting.
Google Cloud is verified on the Green Web Foundation directory. Pricing is comparable to AWS and Azure — you are not paying a green premium.
Hetzner is a German hosting company with data centers in Nuremberg, Falkenstein (Germany), and Helsinki (Finland). All German and Finnish facilities run on 100% renewable electricity — sourced from hydroelectric and wind power in the Finnish case, and from a mix of certified renewable sources in Germany. PUE at the Falkenstein campus is approximately 1.15.
What makes Hetzner exceptional is pricing. A dedicated server with 64 GB RAM and 2 TB NVMe storage runs around €40/month — roughly 60-70% cheaper than equivalent AWS or Google Cloud instances. For developers, agencies, and SMBs running high-traffic sites who do not need hyperscale cloud features, Hetzner is the most cost-effective verified green option available.
Hetzner is listed on the Green Web Foundation. Annual sustainability reporting is less detailed than Google or Microsoft, but their renewable energy sourcing documentation is publicly available.
GreenGeeks is the most well-known green shared hosting provider and a staple of the Green Web Foundation's verified directory. The company purchases 300% renewable energy certificates — meaning for every kilowatt-hour it consumes, it funds three kilowatt-hours of renewable generation. This makes GreenGeeks technically carbon-negative from an electricity standpoint.
Plans start at $2.95/month (promotional) and include cPanel, free SSL, and unlimited storage for typical shared hosting needs. Performance is solid for shared hosting: SSD storage, LiteSpeed web server, and a built-in CDN.
The honest caveat: RECs are a market mechanism, not physical renewable electricity. GreenGeeks' actual data center operations still draw from the conventional grid. The 300% REC purchase does fund renewable energy investment, but it is not the same as a Hetzner or Infomaniak setup where the electrons are verifiably clean.
OVHcloud is Europe's largest cloud provider and has invested heavily in genuine renewable energy infrastructure. Its Strasbourg campus draws significantly from Rhine hydroelectric power. The company achieved 78% renewable electricity in 2024 and is targeting 100% by 2026. Its proprietary water cooling system (no chillers, direct water cooling for servers) enables a PUE of 1.09 at its best facilities — matching the performance of Google's hyperscale campuses.
OVHcloud is particularly strong for European GDPR compliance and data sovereignty requirements. Its pricing is competitive with Hetzner for dedicated infrastructure, and it offers a broader product range including public cloud (compatible with OpenStack APIs), managed Kubernetes, and dedicated bare metal servers.
Amazon Web Services achieved 100% renewable energy matching across its global infrastructure in 2023. The company has invested in over 500 solar and wind projects globally, making it one of the world's largest corporate renewable energy buyers. Its fleet-average PUE of 1.20 is above Google's but below the industry average of 1.58.
AWS's sustainability credentials are more complex than Google's. Not all AWS regions have the same grid cleanliness: US-East-1 (Northern Virginia) runs on a less clean grid than EU-West-1 (Ireland) or US-West-2 (Oregon). AWS's customer carbon footprint tool allows you to see per-service, per-region emissions estimates — and importantly, to choose lower-carbon regions for new deployments.
For teams already in the AWS ecosystem, switching regions to Oregon or Ireland meaningfully reduces your website's carbon footprint without any other changes.
Kualo is a UK-based hosting provider that has built its brand around genuine environmental commitment. The company runs on 100% renewable energy and has planted over one million trees through partnerships with Eden Reforestation Projects and similar organizations. It claims carbon-negative operations when tree-planting carbon sequestration is factored in.
Shared hosting starts at around £3.95/month. Performance is competitive for European audiences, and the company has a strong reputation for support. It is listed on the Green Web Foundation. For UK-based SMBs or charities with audiences in Europe, Kualo offers an accessible green hosting option without enterprise complexity.

The green hosting market is full of providers making claims that do not hold up to scrutiny. Here are the patterns to watch for:
Switching hosts is the single largest lever most website owners have for reducing their digital carbon footprint. But it is not the only one. The data center accounts for 28% of total page view energy — the remaining 72% comes from network transfer and end-user devices, both of which are driven primarily by page weight.
A practical approach to website sustainability works across three layers:
The combination of green hosting plus page weight optimization can reduce a website's total carbon footprint by 50-70% compared to an unoptimized site on conventional hosting. For a site with a million monthly page views, that is the difference between 576 kg and roughly 173 kg of CO2 per year.
Before signing up with any host claiming green credentials, run through this checklist:
A genuinely green web host either generates on-site renewable energy, holds verified Power Purchase Agreements (PPAs) for renewable electricity, or purchases Renewable Energy Certificates (RECs) matching 100% or more of its consumption. The Green Web Foundation verifies these claims against actual documentation — check their directory before choosing a host.
No. Shared green hosting from providers like GreenGeeks or Infomaniak starts at $3–5/month, on par with conventional hosts. Enterprise cloud pricing at Google Cloud, AWS, and Azure is identical regardless of renewable energy commitments. The price premium for going green is typically less than 5% and often zero.
Check the Green Web Foundation's verified directory at thegreenwebfoundation.org/directory. Ask your host for their REC certificates or PPA documentation. Look for annual sustainability reports with third-party audits. Avoid hosts that claim "carbon neutral" without specifying whether they use renewable energy, RECs, or offsets.
PUE (Power Usage Effectiveness) measures how efficiently a data center converts incoming electricity into useful computing power. The global average is 1.58. A green host with a PUE of 1.1 wastes only 10% of incoming electricity. Lower PUE means less total energy drawn from the grid, amplifying the impact of renewable sourcing.
Yes, by approximately 75% of the data center segment. According to the Sustainable Web Design Model v4, the data center accounts for 28% of a page view's total energy. Switching to a verified green host reduces that segment by ~75%, cutting your site's total footprint by around 21%. Combine this with page weight optimization for maximum impact.
