What is Dark Data
At The ESG Institute, we believe that advancing sustainability starts with understanding the language that shapes it. Our "ESG Terms" series breaks down complex, often overlooked concepts in sustainability and Environmental, Social, and Governance (ESG) reporting—so you can stay informed, inspired, and one step ahead in your journey toward responsible business.
What is Dark Data?
🔺 Dark Data refers to the vast amounts of collected but unused digital information stored in databases, servers, and cloud systems. This data—often forgotten or unnecessary—still consumes energy, contributing to carbon emissions and digital waste.
🔺 Why It Matters: While we often focus on physical waste, digital waste is an invisible but growing problem. Data centers account for approximately 1% to 1.3% of global electricity consumption. Storing unnecessary data increases energy demand. By managing Dark Data effectively, businesses can cut costs, lower emissions, and optimize their IT sustainability strategies.
🔺 Example: Many companies store redundant, obsolete, or trivial (ROT) data—such as outdated emails, logs, or duplicated files—without realizing the hidden environmental cost. A simple data audit and deletion policy could significantly reduce energy consumption and free up valuable storage.
🔺 Did You Know?: According to a report by Splunk, approximately 55% of an organization's data is dark, consuming vast amounts of energy without providing any value.
