Green Web Hosting

The Internet is a menace to our environment, but it needn't be this way. That's why we're committed to making sure our corner of the web is as green as can be, through a comprehensive environmental strategy that both reduces our impact today, and invests in the future.

100% Green Powered Hosting

Our global operations are powered entirely by renewable energy. Our UK datacentre uses 100% green sourced power as specified by E.ON and as regulated by Ofgem, and our US facility uses 100% renewable energy, as certified by Green-e.

Energy Efficient Datacentre

Our datacentre is built from the ground up to be efficient, with a PuE rating of between 1.2 and 1.3 and environmental management policy externally assessed to ISO 14001 standards.

Sensible Green Policies

Our environmental policies aim to reduce waste, encourage recycling and avoid all unnecessary travel. Although we have offices where we like to get together, remote working is a part of who we are and is always encouraged for a healthy work-life balance.

Tree Planting & Offsetting

In 2020 we committed to becoming a climate positive business. Each month we invest in responsible reforestation efforts and fund climate crisis solutions that have been certified to remove carbon emissions. So far we have planted over 20,000 trees trees and funded efforts that have removed over 100 tons of carbon dioxide.

Picture the scene...

It's a Sunday morning. You've sat down with your coffee and croissant, and you decide to read the news online, check your email or watch the latest YouTube sensation.

This little scene may seem innocent enough, but did you know that what you've just done had an environmental impact? Would you be surprised to learn that it contributes to a beast that produces an enormous and ever-growing amount of carbon?

Real-World Mechanics

As ephemeral as it all seems, it's easy to forget the real-world mechanics that go into keeping the Internet running. A web site is housed on a server in a datacentre - a building packed top to bottom with servers which power the web pages, videos, online applications and downloadable files that make the modern online experience possible.

All these servers require electricity to keep them powered up, and then almost as much again to keep them cool. To generate much of that electricity, fossil fuels like coal and gas are usually being burned.

The internet is a filthy, carbon-emitting monster.

The Kualo Way

We're passionate about web sites, but moreover, we're passionate about ensuring they don't damage our environment.

100% Renewable Power

Truly green hosting starts with 100% renewable power.

In the UK, our datacentre runs on 100% green-sourced power as specified by E.ON (the Supplier) and as regulated by Ofgem. E.ON are one of the leading renewable generators in the UK with over 20 on-shore and off-shore wind farms, including the London Array, the world's largest off-shore wind farm with a capacity of 630MW.

We also use renewable energy for 100% of our U.S. operations, as certified by Green-e, North America’s leading voluntary certification programme for renewable energy. We have additionally been recognized by the U.S. Environmental Protection Agency as a Green Power Partner. Our renewable energy is sourced through Native Energy, one of the few genuinely high-integrity businesses in the sector. Their projects go beyond simply generating renewable energy, but moreover, deliver social benefits for the communities in which those projects are located, including schools, family owned farms and Native American tribes.

We are also partner member of The Green Web Foundation, a not-for-profit organisation who are on a mission to speed up the transition towards a completely green Internet. You can verify whether your site is running on renewable energy on their website.

E.ON's 630MW "London Array", the world's largest off-shore wind farm, which reduces CO2 emissions by 900,000 tons annually.

NativeEnergy's "Greensburg Wind Farm", which helped revitalise a community devastated by a 2007 EF-5 Tornado.

Energy Efficient Data Center

Even renewable energy is precious - so the next step in the process is to ensure that use of that electricity is also kept to an absolute minimum, which starts with intelligent datacentre design.

Our primary hosting facility, Centro, is not only powered entirely by renewable energy, but has also been built from the ground up to be extremely energy efficient. Part of The Green Grid industry body, Centro complies with the EU datacentre code of conduct and is audited and certified to ISO 14001 (Environment Management) standards. The facility achieves a class-leading PUE (Power usage effectiveness) of 1.2, making it one of the most efficient hosting facilities in service today.

In the typical datacentre, a huge amount of energy is used to keep the servers cool - generally this is because inefficient design principals have been employed. In the vast majority of datacentres, the server rooms are kept exceedingly cold, but the servers sit there blowing out a heap of hot air back into the room. A huge amount of energy is thereby wasted constantly having to re-cool that hot air again, causing the cooling systems to work harder and consume more power than they ought to.

In Centro, the hot air expelled from the servers is contained and directly extracted from the building, meaning the cooling systems can operate much more energy efficiently. The super efficient water-based chillers additional use 'free cooling' technology, which means that when it's cool enough, the outside air can just be pumped through rather than waste energy keeping the chillers running at full-speed.

Sensible Green Policies

Being environmentally conscious is at the heart of everything we do. Along with a super-efficient, green powered datacenter, as a company we also:

  • Use energy efficient servers with high-efficiency power-supplies and smart sensors to control fans so that they only provide cooling when required
  • Cycle out older server hardware to newer more efficient technology as it becomes available
  • Operate a completely paperless system with all customer invoices and receipts sent out in electronic format
  • Avoid printing unnecessary documents and recycle all unneeded paper
  • Encourage staff to work from home to minimise unnecessary commuting
  • Avoid all unnecessary travel

Tree Planting & Carbon Offsetting

Our business is also powered by humans. Lovely humans. Humans who work tirelessly to ensure our renewably powered servers keep humming, and our customers' questions are answered in record time. But these humans each have their own carbon footprint. That's why we are committed to having a climate positive workforce, which means that for every member of our team, every month we plant 12 trees and offset 1.2T of CO2.

We also consume carbon in other ways, through the equipment we purchase, and the supply chains we use. That's why we are also committed to off-setting substantially more carbon than we consume, as well as planting more than 1,000 trees every single month. We are also committing to "pay back" our historic carbon consumption since we were founded, and by the end of 2025 we are committed to offsetting over 5,000 tons of CO2 so we may become truly carbon negative.

  • We are committed to planting a tree for every order we receive. So far we have planted over 20,000 trees.
  • We are committed to planting 12 additional trees for each of our employees, every single month.
  • We are committed to offseting more carbon than we consume as a company, every single month.
  • We are committed to becoming truly carbon negative, by "paying back" more carbon than we have consumed since we were founded.

To make this possible, we have partnered with Ecologi, who facilitate our tree planting and carbon offsetting. Ecologi work with responsible tree planting partners and invest in projects that are certified at the very highest level to remove greenhouse gasses. They are extremely transparent about their financials, and are backed by a superb team.
