The global data centre energy consumption is expected to double to 1,000 TWh this year, according to the IEA report. Businesses monitor their fleet emissions, supply chain, and also offset air travel. But when will they finally pull the plug on the devices running nonstop on every employee’s desk, or the servers taking up gallons of water and heating up the planet, just to run their website, cloud storage, and emails?

Many organisations still struggle to measure where their biggest carbon emission sources are. But the absolute foundation of digital carbon footprint is the technology, although it is a defensible point that technology is both the problem as well as one of the most powerful levers to reduce your business’s digital carbon footprint, if used right. Here is how to decarbonise the digital footprint of your business.

What Is a Digital Carbon Footprint?

Digital carbon footprint refers to the extensive greenhouse gas emissions produced by a business’s technology, such as from the hardware it uses, to the energy consumed by the servers hosting its website.

Astonishingly, the sources are even greater than that. Communication devices, emails, video calls, cloud storage, AI tools, and even printers, all contribute to the digital carbon footprint. 

In 2026, digital emissions fall directly under ESG reporting frameworks. If your business is under the scrutiny of an investor, client, or regulatory authority, you must address its digital carbon footprint. The values a business holds determine how fast its products or services sell, and if its digital sustainability becomes a baseline expectation, it can quickly establish a reputation among high-net-worth clients.

Why Digital Carbon Footprint Accountability Matters in 2026

Three reasons have made climate-conscious businesses prioritise digital carbon footprint accountability.

Regulation

Compulsory ESG reporting has made large businesses conscious because they must make public the environmental harm/effects of their digital activities. This means that they should be responsible about hosting, cloud storage, and digital emissions.

Investment

The ESG-focused institutional investment has sprung up and is expected to grow from $45.61 trillion in 2026 to $180.78 trillion by 2034. It’s now a rule of thumb that investors are supporting the businesses that can display their sustainability credits, and digital emissions are now part of that scrutiny.

AI

AI uses 10 times more energy than a Google search. Even then, many businesses use it for training and querying. But on the other hand, AI search tools like ChatGPT, Claude, and Gemini are used by customers to evaluate brands. This is why businesses cannot ignore the influence of AI entirely. Businesses are standing at a crucial point where they are expected to use AI tools for their productivity and improve visibility on the search tools, while also mitigating the massive carbon footprint that AI produces.

How to Reduce Your Business’s Digital Carbon Footprint in 2026

Step 1 – Measure Your Emissions

Measure your digital carbon footprint with an audit that covers employee devices, networks, cloud storage, email storage, your website, and your website hosting.

There are many free tools to do that, such as Website Carbon Calculator, which estimates CO2 per page view; Ecograder, which audits site performance; Green Web Check, it verifies the energy source of your hosting provider; and GreenFrame, which keeps an eye on web application emissions. If you want to immediately reduce your digital carbon footprint, share files via cloud links and do not share them in email attachments.

Businesses that are building their websites on climate-positive hosting, whose servers run on 98% renewable electricity, are avoiding massive emissions in the hundreds of tonnes each year.

Step 2 – Manage Your Data

Your business stores even more data than you think. For starters, there are emails such as reply-alls, unread newsletters, and large attachments. These emails accumulate and take up massive storage over time. Cloud storage has duplicate files, outdated documents, and unused software which must be deleted immediately. Make sure you send out as few ‘thank you’ emails as possible.

Video calls generate a huge digital carbon footprint. That is why, turn off the camera during routine check-ins and only turn it on for important meetings. This simple step can reduce your business’s carbon emissions by up to 80%. And lastly, take care of how much AI your company is using. Make sure that you and your employees are only using AI where dire needs arise.

Step 3 – Upgrade Your Infrastructure 

Many businesses overlook how much carbon footprint their cloud providers and devices produce. That is why you must only choose serverless or environmentally conscious cloud models that consume resources only when needed. Almost 83% of a laptop’s total carbon footprint is generated when it is manufactured. So keep your devices longer, repair them rather than replace them, and buy second-hand or refurbished equipment. Wireless chargers use double energy as wired chargers, and devices left on standby overnight also contribute to the overall energy consumption.

B Corporations and businesses for whom the greatest asset is the brand reputation, these infrastructure decisions can make or break their brand story, so much so that clients and partners notice.

Step 4 – Make Your Website Work Efficiently

The average website produces 0.36 grams of CO2 per page view. But an optimised website on green hosting can reduce that figure by 80-90%.

If you want to dissect the technicalities, make the following changes, and you will notice a huge reduction in your digital carbon footprint.

Compress images into modern formats such as WebP or AVIF. Enable browser and server-side caching. Minify code files. Get rid of unused plugins. Implement lazy loading.

Furthermore, switch to a green provider running on renewable energy. Businesses that have made this switch with a full website redesign have seen double the organic traffic, decreased bounce rates, and a strong revenue. These results are not only because of the hosting, but also because of the functional, fast, and sustainable build, which makes the user experience and search engines’ crawlability efficient.

Step 5 – Make Your Company Comply

Businesses can only successfully reduce their digital carbon footprint when the whole team cares about the emissions and the planet. A visionary founder, or one or two people in IT taking care of the hosting, won’t do it.

So, train your staff to be more mindful. Ask them to declutter their inboxes, store files responsibly, turn off the devices when leaving for home, and do not turn on their video during calls unless asked. Set targets that respect ESG reporting cycles. 

At the end of the day, it is the conscience that counts. Leading businesses around the world are already targeting their carbon emissions and want to reduce them by 2030. These businesses are also funding thousands of trees to make the environmental effects less severe. The culture your business holds internally will return in the form of customers’ and investors’ respect.

Conclusion

With the global environmental effects manifesting as climate hazards in every country, businesses, their customers, and every other person in the whole supply chain have become alert of the harm that carbon emissions do. It is high time that businesses stop relying on fossil fuels, and embrace sustainable practices. By reducing your digital carbon footprint in 2026, not only will you become more responsible, but also resilient against energy crisis, reputational damage, and supply chain unpredictabilities.
