Looking for ways to reduce your company's carbon footprint? Find out how cloud migration can be an invaluable part of your green agenda.

Cloud providers don't have spotless green records. Their hyper-facilities are big consumers of electricity and water. But on the other hand, the biggest of the bunch are "some of the largest purchasers of renewable energy".

That's according to David Mytton, Environmental Technology MSc student at Imperial College London. He goes on:

"Although it does not guarantee that all energy going into a data centre is renewable, due to the power mix of the local grid, [large cloud providers] can at least match their electricity usage with purchases of renewables elsewhere.

"Google has been doing this since 2017 and both Microsoft and Amazon will do it by 2025. In the meantime, Google and Microsoft are already carbon neutral through purchasing offsets."

On top of that, there are initiatives like Microsoft's Project Natick, which has successfully deployed subsea data centres. These don't need cooling – that job is done by the sea itself.

Then there's Amazon's use of recycled water for cooling and Google's use of AI to reduce cooling costs by 40%.

The other thing to remember is that these huge data centre facilities are being used by an equally huge number of individuals and companies.

If every business in Belgium (let's say) had its own on-premise data centre, that would be far less sustainable than if they all used a cloud provider.

It's the same principle as using an electricity grid rather than having your own private generator. The resources are shared among multiple users, which increases efficiency.

Cut down on paper

It would be a sad world without paper – the stuff of journals, birthday cards and love letters.

But will a finance officer really miss paper payslips? Will anyone working for a company miss box files, filing cabinets and lever arch folders?

It's not just that those mountains of paper need to be kept somewhere – and that the more you have, the harder it is to navigate.

It's also that paper production is pretty bad for the environment.

Using cloud-based tools for documentation allows you to go fully paperless – slashing your carbon emissions as well as creating space in your branch or home office.

Cut down on "e-waste"

Paper isn't the only waste that companies produce. There's also the phenomenon of "e-waste" or electronic waste.

This is anything with a plug or battery – and it's filling up landfill all the time.

The UN has reported that the world will produce 74 tonnes of e-waste each year – and less than 40% of e-waste produced by the EU gets recycled at all.

Your on-premise data centre is a breeding ground for e-waste. Shifting your data and apps off-premises and onto the cloud means you can give your facilities a spring clean – and stay on track with your sustainability targets.

Remote working

The COVID-19 pandemic didn't invent cloud migration – but it certainly gave it a massive push.

Global lockdowns meant that remote working was a necessity, not – in most cases – a choice. The FT reported how office space in England shrank by millions of square feet – and it was the same story pretty much everywhere.

Emerging from the pandemic, remote or hybrid working has become the norm. It's one of the few pandemic-induced innovations that we've held on to as a positive change.

Cloud computing allows your teams to access what they need from any location – whether that's a home office, an armchair or the backseat of a rickshaw.

All you need is a secure internet connection and access permission. Other than that, the world's your oyster and the sky's the limit.

Cloud computing is the foundation of remote working. Without it, your national post service would collapse under the strain.

Remote working can have a positive impact on productivity and employee well-being. But it's also better for the planet.

Travel is a huge contributor to a company's carbon footprint – whether it's the emissions produced by commuting or through getting everyone in the same place for a meeting.

Embracing hybrid working means you can slash your travel costs – a move that could help you meet your sustainability targets.

Root out obsolete workloads

Do you have a drawer at home that's filled with rusty batteries, snapped pencils and electronic cables of uncertain origin?

Most companies have a digital equivalent – data and software that once served a purpose but is now just taking up space and CPU.

In practice, that means carbon. By rooting out your obsolete workloads, you can make your company greener than ever before.
