Sustainable Cloud

Grøn Sky is your low-emission cloud solution, where you can store your holiday photos and other valuable documents with a clear conscience.

Instant or Long-term

Most people don’t need instant access to all their files in the cloud. Store some of your data on our dormant hard drives that only use power when you access them.

CO2 Reduction

Data stored in our Long-term storage reduces CO2 emissions by almost 90% compared to regular cloud storage.

Renewable energy sources vary from region to region, which affects the CO2 emission from energy production.
In the USA 1 kilo Watt emits 1.54 lb/0.7 kg CO2 per hour.
In EU 1 kilo Watt emits 0.66 lb/0.3 kg CO2 per hour*.
In ASIA 1 kilo Watt emits 1.05 lb/0.475 kg CO2 per hour.
(Our CO2 calculator is based on a formula where 1 Tb of data stored on a server consumes 11.3 Watt per hour.)
*Oracle's cloud is powered by 100% renewable energy in Europe.

Store your memories

By choosing a green cloud solution, you choose to be part of the green internet revolution. This area is often overlooked in the discussion of reducing greenhouse gasses – Even though CO2 emissions from the internet equals the carbon emissions from all air traffic in the world!

What sets Grøn Sky apart from other cloud services is that we store your uploads a bit differently. We don’t believe that everything needs to be instantly reachable, as a very big percentage of uploads are rarely (if ever) looked at again. Think about all your old assignments, photos, receipts, etc. The ones you don’t want to delete, just in case you might need them someday.

Our solution is to divide your uploads into instant access and long-term storage. The system automatically helps you identify which files you don’t use that are suitable for long-term storage. You can still retrieve your long-term storage files within a few hours, if you need them.


We have launched a crowdfunding campaign for Grøn Sky, allowing you to store your files with minimum environmental impact. With your backing, we can develop Grøn Sky for mobile devices as well and add a range of smart features. Join our VIP list and get the inside story of how and why we developed Grøn Sky.

Global Goals

Grøn Sky helps combat climate change while working on the United Nations’ Sustainable Development Goal 13. Not just via our cloud solution, but by every aspect of our company. That’s why we participate in the climate initiative ’CO2 neutral websites’ where the carbon emissions from our website have been neutralized by 200%.
