For companies with ESG commitments or eco-friendly customers, where your data is hosted can have a significant impact on carbon emissions. An overseas host may rely on fossil fuels and increase emissions due to long-distance data transfer. In contrast, UK data centres are increasingly powered by renewable energy and governed by strict efficiency standards. In this post, we examine the carbon cost of overseas hosting and explain why UK-based data centres are greener.

The carbon footprint of global data hosting
The demand for data centres is greater than ever. According to Goldman Sachs, the growth of AI is expected to increase global data centre power use by 160% by 2030. It’s not just AI and business applications that consume energy; so too do all website visits, searches and server transactions. A typical page view generates around 0.5g of CO, and with 5.5 billion internet users making an average of 6 to 10 page visits a day, the internet’s annual carbon footprint is huge.
The amount of CO2 generated also depends on where data centres are located. Many countries still rely heavily on coal and gas to power their data centres, and if your host is located in those countries, your business operations will be contributing to those higher emissions.
According to Reuters, US utility companies are building new gas plants and postponing the retirements of fossil-fuel power plants to ensure the grid can cope with data centre demand. The US has a third of all the world’s data centres, and many UK companies are hosted with them.
British companies with overseas hosting may also generate more CO2 through data transmission. The further the data has to travel, the more energy is needed for networking and cooling across the route. If you’re a company with a UK audience but have hosting in North America or Asia, not only does this mean a larger carbon footprint, but it also increases latency, slowing down your website’s loading and response times.
Why UK-based data centres are greener
Compared to many other countries, the UK is well-positioned when it comes to sustainability. By the end of 2024, over half of the UK’s electricity was generated from renewable sources, like wind, solar, biomass and nuclear power. This means that businesses hosted at UK-based data centres will make increasing use of low-carbon energy sources.
There is also greater surety that UK providers are working towards net zero. British data centres are subject to strict regulations and efficiency standards, and providers have to comply with environmental performance obligations. As a result, UK-based hosting not only cuts emissions but also ensures compliance with the environmental expectations of regulators and customers.

How Webhosting UK reduces environmental impact
At Webhosting UK, sustainability is integral to our operations. We recognise the environmental impact of our UK-based data centres and are committed to eradicating this and achieving net-zero carbon emissions. Our key initiatives include:
- ISO 14001 certification – this demonstrates effective environmental management and resource efficiency across all our UK data centres.
- ISO 50001 accreditation – this proves our continuous improvement in energy management and in reducing consumption.
- SECR and ESOS compliance – this ensures we meet national carbon reporting and energy-saving obligations.
- Renewable Energy Guarantee of Origin (REGO) certificates – this confirms that our data centres are powered by renewable energy.
- Efficient infrastructure – By replacing HDDs with SSD and NVMe drives, we have cut the energy use of our servers by 50% at load and 87.5% at idle, while also reducing hardware turnover.
- Advanced cooling – cold aisle containment and ASHRAE-compliant airflow design reduce the demand for power-hungry cooling.
- Offsetting and restoration – through Project Green Connect in India, we are helping to plant one billion trees to offset our and our customers’ emissions.
- Sustainable workplaces – we have moved to smaller, energy-efficient offices and adopted remote working to reduce commuting-related CO2.
- Recycling – we responsibly reuse and recycle servers and hardware to ensure minimal waste.
These measures show that our green commitments extend much further than energy supply and encompass all aspects of our operations and supply chain.

Aligning hosting with ESG and net-zero goals
Sustainability is more than just a corporate value; it is a regulatory, customer and investor expectation. Indeed, many businesses now report Scope 2 and Scope 3 emissions as part of their ESG obligations. Your choice of hosting provider will affect those figures, as emissions from purchased energy and supply chains have to be accounted for.
By choosing a UK-based provider with renewable energy-backed data centres, businesses can significantly reduce their reported emissions, improve compliance with SECR and ESOS, and demonstrate their support for the UN’s Sustainable Development Goals. Moreover, it also lets your customers and stakeholders know that your company is committed to sustainable practices.

Key takeaways
- Overseas hosting can increase carbon emissions due to fossil fuel reliance and long-distance data transfer.
- UK data centres benefit from renewable energy and strict efficiency regulations.
- Choosing a UK-based provider helps businesses cut Scope 2 and 3 emissions.
- UK hosting reduces impact through ISO certifications, renewable power and energy-efficient infrastructure.
- Hosting locally supports ESG commitments and net-zero goals.
Conclusion
With a reliance on fossil fuels and the need for long-distance data transmission, the carbon cost of having overseas hosting can be much higher than many businesses realise. With a UK-based host, you are better placed to reduce emissions, comply with net-zero and ESG commitments and improve the performance of your website.
