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 U.S. datacenter uses 100% renewable energy, as certified by Green-e, and our U.K. datacenter uses green-sourced power as specified by E.ON and as regulated by Ofgem.

Energy Efficiency

In addition to being 100% renewably powered, our infrastructure is designed from the ground up to be energy efficient through the use of low power servers, virtualization technology and efficient datacenter design with leading PuE levels.

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 began investing in responsible carbon offsetting and tree reforestation projects. So far we have planted over 20,000 trees trees and offset over 100 tons of carbon dioxide. We are committed to remaining carbon negative and to also "pay back" more carbon than we have consumed since we were founded.

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.

We use renewable energy for 100% of our U.S. operations, as certified by Green-e, North America’s leading voluntary certification program 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.

In the UK, our datacenter 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 are also partner member of The Green Web Foundation, a non-profit organization 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 Efficiency

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 energy efficiency at a datacentre and server level.

We choose servers with high-efficency power-supplies, and smart sensors to control fans so that they only provide cooling when required. We use centralized storage on our shared, reseller and virtual servers to ensure that we make the most efficient use of hardware, reducing the number of servers required to service our customer base. Finally, we cycle out old hardware as newer, more efficient technologies come to market.

At a datacenter level, our datacenters are highly efficient with leading PuE ratios as low as 1.2, thanks to use of energy efficient technologies such as hot aisle containment, free cooling and automatic sensors on facility lighting.

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:

  • 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 at least 1,000 trees, every single month. 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.
