The impact of cyber security

Practices like encryption and data protection are essential for safeguarding sensitive information, but they also contribute to increased energy consumption, which affects the environment.

A study conducted by Lancaster University in the United Kingdom shed light on the energy consumption associated with cybersecurity activities, including encryption, decryption, and secure communication protocols. The findings revealed that such activities contribute to carbon emissions, and the researchers estimated that global CO₂ emissions related to cybersecurity could reach 8.4 megatons by 2020.

The environmental impact is further compounded by the energy-intensive nature of cryptographic algorithms. These algorithms demand significant processing power, leading to higher energy consumption and, in turn, more carbon emissions. Moreover, data centres, which host and power these cybersecurity measures, also play a substantial role in the overall environmental impact.

To address these challenges responsibly, VET practitioners should adopt eco-conscious practices in their daily work. Minimising the use of energy-intensive security measures whenever possible is a practical step. Simple actions, such as turning off unused devices and optimising power settings on computers and other equipment, can collectively make a positive difference.
