Protecting the Planet

Welcome to green web hosting – better for you and kinder to the planet.

Every website, database, and digital workload runs on infrastructure that demands energy. From data centres to networking hardware, the internet’s footprint is growing fast and today, the entire ICT sector accounts for an estimated 2-4% of global electricity consumption (Source: Ericsson). Much of this still relies on fossil fuels. We believe hosting should be part of the solution, not the problem.

Building a greener web starts with the right foundation.

Our mission is simple: to deliver uncompromisingly fantastic web hosting solutions that perform for you, support the planet, and contribute to a greener internet. We’re not perfect, but we’re committed to doing our part and constantly improving.


Green hosting

We’re committed to powering our data centres with 100% renewable energy from the sun, wind, and sea. Rather than relying on offsets, we ensure our operations are directly powered by clean energy wherever possible. As we continue to grow, we prioritise working with data centre partners who share our sustainability values—ensuring our infrastructure remains as energy-efficient and low-impact as possible.

Energy efficient data centres

All our data centres operate with a PUE rating of 1.2 or lower. PUE, or Power Usage Effectiveness, measures the ratio of total energy used by a data centre to the energy delivered to computing equipment—the closer to 1, the more efficient the facility. Our flagship UK datacentre, for example, has a PUE of 1.05, meaning only 5% of its energy is used for infrastructure like cooling and power, with the rest reaching the servers.

Netwise East

PUE = 1.05

We currently operate from one hall in this brand-new data centre in East London, with the option to expand into a second hall as we grow.

Trees planted so far

Reforestation plays a key role in our mission to reduce the environmental impact of hosting. For every Krystal customer, we plant a tree each month. Through partnerships with global tree-planting organisations, we’ve helped rebuild communities and restore natural habitats. As a Krystal customer, you’re contributing to this effort. Log in to your client area to track your impact and watch your virtual forest grow, tree by tree.

We also take responsibility for the carbon footprint of our team. Every Krystal employee has their emissions offset—not just for the time they work with us, but for their past footprint before joining too.

Green Initiatives

If the UK is to meet its net-zero commitment by 2050, businesses must play their part—and we’re no exception. The journey to a sustainable future is one we must take together. That’s why we’re proud to work with the following organisations…

  • One Percent for the Planet

    As members of 1% for the Planet, we’ve pledged to donate at least 1% of our revenue to support environmental causes worldwide. Through these contributions, we’re working with thought leaders, communities, and impactful projects to drive sustainable change and foster a healthier planet.

  • 1t.org

    1t.org is a World Economic Forum initiative with a mission to mobilise, connect, and empower the global reforestation community to conserve, restore, and grow one trillion trees by 2030. In October 2021, we pledged to protect and plant one billion trees by 2030 as part if this effort.

  • Veritree

    So far, we have planted over 3,000,000 trees through Veritree. Veritree provides businesses and non-governmental organisations with tools and technology designed specifically for large-scale reforestation. A key partner in our own Billion Tree Pledge, Veritree exists to create local jobs, sequester carbon, and help restore ecosystems by planting the right trees, in the right places.

  • Ecologi

    With Ecologi, we have planted over 1,000,000 worldwide. We also support Gold Standard-certified sustainability projects—independently verified initiatives that create real carbon reductions. Learn more about Gold Standard.

    We also enrol our 70+ remote team members in monthly climate-positive subscriptions, planting 4 trees and offsetting 0.66 tonnes of CO2 per employee every month. For new starters, we go a step further—offsetting their entire lifetime carbon footprint up to the point they join us and continue to offset their emissions throughout their time with us.

  • B Corporation

    In early 2023, we became a B Corp, making it part of our legal mission to have a positive impact on both society and the environment. It’s not just about sustainability—it’s about being a business that puts people and the planet first.

  • Million Tree Pledge

    We joined the Million Tree Pledge as a founding member, committing to plant over 1 million trees—and with the support of our community, we made it happen. But the mission doesn’t stop there. The pledge is about driving ongoing impact, encouraging businesses and individuals to commit to large-scale reforestation. If you’re thinking about taking the pledge, you can learn more here.

  • SME Climate Hub

    As members of the SME Climate Hub, we’ve made an internationally recognised commitment through the United Nations Race to Zero campaign. Our pledge is to halve emissions by 2030 and achieve net-zero emissions by 2050.

  • Trees for Life

    We worked with Trees for Life, a Scotland-based charity dedicated to rewilding the Highlands with biodiverse forests. Together, we planted 19,120 trees across the Highlands, helping to restore natural habitats and support a healthy wildlife ecosystem.

Millions of trees, thousands of customers, one shared commitment

Sustainability isn’t an afterthought—it’s built into everything we do. From running our infrastructure on 100% renewable energy to planting millions of trees, we’re committed to a better way of powering the internet. But prioritising the planet doesn’t mean compromising on performance.

Krystal runs on our own in-house cloud platform—built for reliability, efficiency, and long-term sustainability. Building a better internet isn’t just about reducing impact, It’s about setting a new standard for responsible cloud hosting.

This is web hosting without the downsides

Just because we prioritise sustainability doesn’t mean we’re prepared to make sacrifices.
