More than half of the digital knowledge companies generate is collected, processed and saved for single-use functions. Often, it is by no means re-used. This may very well be your a number of near-identical pictures held on Google Photos or iCloud, a enterprise’s outdated spreadsheets that can by no means be used once more, or knowledge from web of issues sensors that haven’t any objective.
This “dark data” is anchored to the actual world by the vitality it requires. Even knowledge that is saved and by no means used once more takes up house on servers – usually large banks of computer systems in warehouses. Those computer systems and people warehouses all use a number of electrical energy.
This is a big vitality price that is hidden in most organisations. Maintaining an efficient organisational reminiscence is a problem, however at what price to the atmosphere?
In the drive in the direction of web zero many organisations are attempting to cut back their carbon footprints. Guidance has typically centred on decreasing conventional sources of carbon manufacturing, by way of mechanisms resembling carbon offsetting by way of third events (planting bushes to make up for emissions from utilizing petrol, as an example).
A digital carbon footprint
While most local weather change activists are centered on limiting emissions from the automotive, aviation and vitality industries, the processing of digital knowledge is already comparable to those sectors and is nonetheless rising. In 2020, digitisation was presupposed to generate 4% of worldwide greenhouse fuel emissions.
Production of digital knowledge is growing quick – this 12 months the world is anticipated to generate 97 zettabytes (that is: 97 trillion gigabytes) of information. By 2025, it may nearly double to 181 zettabytes. It is subsequently shocking that little coverage consideration has been positioned on decreasing the digital carbon footprint of organisations.
When we speak to individuals about our work, we discover they typically assume that digital knowledge, and certainly the means of digitisation, is carbon impartial. But that is not essentially the case – we are accountable for its carbon footprint for higher or worse. To assist scale back this footprint, we have launched the thought of “digital decarbonisation”.

By this, we don’t imply utilizing telephones, computer systems, sensors and different digital applied sciences to cut back an organisation’s carbon footprint. Rather, we are referring to decreasing the carbon footprint of digital knowledge itself. It is key to recognise that digitisation is not itself an environmental difficulty, however there are large environmental impacts that depend upon how we use digital processes in day by day office actions.
To illustrate the magnitude of the darkish knowledge scenario, knowledge centres (accountable for 2.5% of all human-induced carbon dioxide) have a larger carbon footprint than the aviation trade (2.1%). To put this into context, we have created a device that may assist calculate the carbon price of information for an organisation.
Using our calculations, a typical data-driven enterprise resembling insurance coverage, retail or banking, with 100 workers, would possibly generate 2,983 gigabytes of darkish knowledge a day. If they have been to maintain that knowledge for a 12 months, that knowledge would have an identical carbon footprint to flying six instances from London to New York.
Currently, corporations produce 1,300,000,000 gigabytes of darkish knowledge a day – that’s 3,023,255 flights from London to New York.
The fast progress of darkish knowledge raises vital questions on the effectivity of present digital practices. In a research just lately revealed in the Journal of Business Strategy we recognized methods to assist organisations reuse digital knowledge, and spotlight pathways for organisations to observe when gathering, processing and storing new digital knowledge. We hope this will scale back darkish knowledge manufacturing and contribute to the digital decarbonisation motion, which we will all need to have interaction with if web zero is to be realised.
