since 2006 · serving the planet.. one website at a time.

The web host that gives back more power than it uses.

Carbon-neutral from our first day in 2006, and carbon-negative since 2021, not through offsets, but because our servers run on renewable power and our office exports more solar electricity than it draws. Socially responsible and independently owned. Operated by humans. Sign up or schedule a discovery call today!

Need a domain name as well?

Search for one here. Registering a domain and hosting a site are two separate things — you need both, and we can do both or either one.

Welcome, and thanks for visiting. Sustainable Hosting is the world’s oldest hosting company that has been carbon-neutral since the day it opened, and carbon-negative since 2021. We put more renewable electricity into the grid than we take out of it. We are independently owned, based in Antwerp, and small enough that you will get to know us.

What is “admin time”?

Included time with our technical team, by appointment, for whatever you need — brainstorming a project, chasing a problem, or even something that has nothing to do with your hosting at all. Unused minutes roll over for a few months, so they accumulate if you do not need us.

Paying yearly costs ten times the monthly price, so two months are free. Prices are quoted without currency; customers outside North America will be billed in Euros. We will always speak to you about your project before demanding any payment, and refunds may be requested within 30 days if either of us finds we’re not a match for each other.

Who we host for

Your mission first. Always has been. Always will be. Count on it.


NGOs

Work that crosses borders needs infrastructure that does too. Resilient DNS, multilingual WordPress, privacy-respecting analytics, and hosting that will not embarrass you in a funding report.

Hosting for NGOs →

Non-profits

Real budgets, volunteer turnover, and a donation page that must not fall over on the big day. Discounts up to and including free hosting for organizations doing work that deserves it.

Hosting for non-profits →

Green business

If sustainability is in your pitch, your hosting should survive being asked about. Ours does: renewable power end to end, and figures we publish rather than imply.

Green web hosting →

Small and medium business

A shop, a practice, a studio, a consultancy. You need the site up, the mail delivered and the invoices to make sense, not a dashboard with forty tabs. Fixed yearly pricing, included admin time, and humans with names that already know what you run and what you’re likely to need.

Hosting for small businesses →

Conscious individuals

People who would rather their personal site and their email did not run on someone else’s advertising business. Your own domain, your own mailboxes, renewable power, and no data sold or mined. One site, a handful of addresses, a fixed yearly price, and someone who picks up, and for about what a streaming subscription costs.

Beyond basic web hosting

The rest of what we do


We started as a plain web host in 2006 and never stopped adding things people asked us for. If something you need is not here, ask… it is how most of this list happened.

Carbon-neutral web design


Built by people, on a performance budget. Fewer plugins, smaller images, real caching… sites that load fast on an old phone and a slow connection.

Read more →

AI website design


AI to accelerate structure and first drafts, humans to review before it ships. Small efficient models on renewable-powered hardware. In development, so ask to be told when it opens.

Read more →

Container hosting with staging


Your site in its own container, with development and staging copies only you can see. Push when you are happy. If something goes wrong, re-deliver it. In testing.

Read more →

Back office utilities


Business phone tree, document management with search, DMARC monitoring, a gentle drip-feed mailer, Nextcloud groupware. The unglamorous things small organizations lack.

Read more →

A tech department you can afford


A named, live-human team for organizations too small to employ one. They see your mission statement, and they usually turn out to care about it.

Read more →

Backup and threat protection


A cheap document-only backup at one end, and Acronis Cyber Protect Cloud on green storage at the other. Because it is a question of when, not if.

Read more →

Green AI compute


Green Cycles, our carbon-aware GPU marketplace in development: training and inference scheduled where and when the grid is cleanest, on hardware run by verified renewable-powered providers.

Show me the receipts

A hosting company claiming to be carbon-negative should be made to prove it.


Fair enough — we would want proof too. In 2006 there was almost nowhere to rent a server that ran on clean energy, so we bought renewable energy certificates and made sure every office we worked from was on a certified renewable tariff. No commute, no separate building running lights and air conditioning around the clock.

Then we found the upstream provider our servers have lived with for over a decade, powered directly by renewables. At that point “carbon-neutral” stopped needing an asterisk about carbon trading.

Today the main office is a home with what the installers described as “clearly too many solar panels”. Anything the panels do not cover still arrives directly from renewable energy sources. The result is that we put more electricity into the grid than we take out — and a meaningful share of what we export, we are never paid for.

Grid electricity, measured

Grid electricity by year: injected, pulled, and the net figure.

Each year we export roughly what an average household uses in two to three months — over and above everything we consume ourselves.

Social responsibility as a top priority

A fair and workable world for everyone.


That commitment informs our decisions, individually and as a company. Being “green,” saving electricity and using it carefully, is only one part of a larger mission, and we have never pretended otherwise. Perhaps it is no surprise that everyone who has been involved here already agreed with it before they arrived, and has gone out of their way to help make the world a cleaner and a fairer place. Our culture keeps attracting the same sort of person, so we expect that to carry on. Which is to say: your patronage contributes to rather more than “just” a reduction in carbon.

When we choose a vendor, we do our due diligence. When we hire a subcontractor, we make sure they are paid fairly. We turn down paying customers whose work we cannot stand behind. Do all of that for long enough and our customers’ missions become our own. That’s why the support is so good, rather than the support being a thing we grudgingly tack on. The change we want to see in the world, everywhere possible!

We believe that taking a passionate part in whatever society and communities you find yourself in is an essential part of living. We are fanatical about voting, for everyone who has the privilege. Please register and VOTE!

What we have been up to

In their words

Our website has been continuously hosted by Sustainable Hosting since 2011. We have also had the benefit of their basic design work throughout, which has kept a working site up at all times. Along with general tech consulting, it has been instrumental to our community outreach. They have always been on hand when something went wrong — malware, spam — ready to pull from their automated backups if needed. We will not be going anywhere else.
