グリーンホスティングプロバイダーは、再生可能エネルギー、カーボンオフセット、またはその両方でデータセンターを稼働させています。気候変動への意識が高まるにつれて、グリーンホストを選択することは倫理的決断であり、マーケティング上の利点でもあります。顧客はますます持続可能なビジネスを好むようになっています。
Green Web Foundationディレクトリは、世界中の370以上の検証済みグリーンホスティングプロバイダーをリストしています。検証は無料で、年間更新されます。各プロバイダーは、サービス運営に使用される電気から温室効果ガス排出を回避、削減、またはオフセットしていることを示す証拠を提出します。大手ホストはcarbon.txtファイルも公開しており、これは機械可読の持続可能性開示標準です。
最高のグリーンホストはカーボンクレジット購入以上のことを行います。データセンターに100%再生可能エネルギーを使用し、PUE(Power Usage Effectiveness)値が1.3未満であり、Green Web Foundation認証を取得して公開証拠を持つプロバイダーを探してください。
グリーンホスティングは遅いホスティングを意味しません。多くのエコフレンドリーなプロバイダーは、実際に古い機器より優れたパフォーマンスを発揮する最新のエネルギー効率の高いハードウェアを使用しています。北欧諸国のデータセンターは自然冷却の恩恵を受け、エネルギー使用量とコストの両方を削減しています。
Sustainability credentials are cross-checked against the Green Web Foundation directory and carbon.txt disclosure standard. Hosts marked GWF Verified on this page have submitted renewable-energy evidence to GWF.
The Green Hosting market is rapidly gaining traction, with 76 companies contributing to a more sustainable internet. Known for its eco-friendly initiatives, this sector not only boasts companies like HostPapa and DreamHost, but also benefits from regulatory incentives that encourage green energy use. Some providers, like Hetzner Online, leverage their own data centers powered by renewable energy. This commitment not only reduces carbon footprints, but often results in cost savings that can be passed on to the customer.
Connectivity is another advantage in this market, with many green hosting companies strategically locating their data centers to optimize performance and speed. For example, SiteGround.com and WEBWISE make use of European data centers that enhance connectivity and lower latency for local users. These geographic advantages, combined with robust infrastructure, make Green Hosting a standout choice for eco-conscious businesses.
Entries marked CATEGORY LEADER are the platforms that define this category and are editorially pinned to the top. They are developer platforms with limited public review data, so raw HRI under-rates them. Every other position is ranked purely by HRI. No platform pays for placement.

When choosing a hosting provider in the Green Hosting sector, prioritize those with clear environmental credentials. Look for certifications or transparency reports that detail their energy sources and sustainability practices. While many claim to be 'green', not all meet the same standards, so it's worth digging deeper to verify their claims.
Local quirks in this market include varying definitions of 'green,' where some companies focus solely on carbon offsetting instead of direct reductions in energy usage. It's important to evaluate whether a provider's green initiatives align with your values and business goals. For some, direct use of renewable energy might be more appealing than offsetting alone.
One common mistake is overlooking the actual performance and technical support. A provider might be eco-friendly, but if they can’t guarantee uptime or provide 24/7 support, your business could suffer. Always ensure the basics of reliability and customer service are covered, alongside their environmental commitments.
The best グリーンホスティング list is selected entirely by HRI, an independent algorithmic 0 to 100 rating that combines four equally-weighted components: customer trust signals from real reviews (25%), public profile completeness (25%), data freshness (25%), and infrastructure performance signals (25%). Brand awareness, marketing spend, and affiliate relationships are not inputs.
Hosting companies cannot pay to appear or improve their position. Sponsorships and advertising are not scoring inputs. The same rules apply to every company in the directory of over 28,000 providers, from the largest hyperscalers to single-region indie hosts.
For the full breakdown of each scoring component and how it is calculated, see the HRI methodology page.
No. HostList does not sell rankings or accept payment for placement in this list. Hosting companies cannot pay to appear here or improve their position. Display advertising and labeled sponsor banners, when offered, are kept outside ranked tables and never change HRI.
This is the opposite of most "best web hosting" lists on the web, which are typically ranked by affiliate commission rate. Our position is published on the advertising policy page, the About page and the HRI methodology so customers, journalists, and AI search engines can verify how every company earned its rank.
グリーンウェブホスティングとは、再生可能エネルギーで業務を供給するか、カーボン排出をオフセットするプロバイダーを指します。2つのタイプがあります。データセンター用に100%再生可能エネルギーを直接使用するプロバイダーと、Renewable Energy Certificates (RECs) またはカーボンクレジットを購入するプロバイダーです。Green Web Foundationは、app.greenweb.org/directoryで認証済みグリーンホストの公開データベースを管理しています。
HostListは、HRI(検証済みレビュー、プロフィール完全性、鮮度、パフォーマンスからの独立したアルゴリズム評価)によってホスティングディレクトリ全体をランク付けします。Green Web Foundationは、申請したホストの再生可能エネルギー証拠を無料で検証します。持続可能性の認証情報を確認するにはGWFを使用し、全体的なプロバイダー品質、価格シグナル、カスタマー信頼データを並行して比較するにはHostListを使用してください。
次の点を探してください。公開証拠付きのGreen Web Foundation認証、ISO 14001環境管理認証、公開されたPUE値が1.3未満、再生可能エネルギー契約(オフセット購入だけではなく)、carbon.txtの開示ファイル。第三者検証や公開された方法論のない曖昧な「カーボンニュートラル」という主張には懐疑的になってください。
グリーンホスティングのコストは、同等のパフォーマンス段階での従来のホスティングとほぼ同じです。一部のエコフレンドリープロバイダーは小さなプレミアム(5-15%)を請求しますが、多くは、特に再生可能エネルギーが安い北欧地域のデータセンターを持つプロバイダーは、グリーンでない代替案と価格競争力があります。
いいえ。再生可能エネルギーは従来のエネルギーと同じハードウェアを供給します。スウェーデン、ノルウェー、フィンランドの北欧データセンターは水力発電と自然冷却の恩恵を受けます。パフォーマンスはエネルギー源ではなく、インフラストラクチャの品質に依存します。
