Terms such as Green, Sustainability, and ESG are no longer confined to boardroom discussions; they are now part of everyday conversations across organizations. This raises an important question: does Green IT truly matter?

According to Wikipedia, “Green computing, green IT, or Information and Communication Technology Sustainability, is the study and practice of environmentally sustainable computing or IT.” Its objectives include:

• Optimising energy efficiency throughout a product’s lifecycle
• Leveraging renewable energy sources to power systems and networks
• Extending product lifespans through reusability, maintainability, and repairability
• Reducing e-waste by improving recyclability and biodegradability to support the circular economy
• Aligning IT practices with environmental and social sustainability goals

These principles apply to all classes of systems, from handheld devices to enterprise data centres. Let us explore their practical relevance.

With rising energy costs, procurement decisions should prioritise equipment that is energy-efficient. Certifications such as Energy Star or Energy Efficiency Ratings serve as reliable indicators. Beyond lowering operational expenses, such investments generate long-term savings while contributing to more sustainable IT operations.

The increasing affordability of renewable energy, particularly solar power, has made adoption far more accessible. The average return on investment for solar energy has improved significantly, now ranging between 7–8 years for residential use and 3–5 years for commercial users, compared to 12–15 years in the past. Additionally, many utility providers now offer mechanisms for selling excess energy back to the grid, further improving cost efficiency over time.

Extending the typical lifecycle of IT equipment from 2–3 years to 5–7 years reduces both costs and environmental impact. Achieving this requires careful planning and procurement of devices with specifications that remain relevant for longer-term use. Such an approach reduces carbon footprints while maximising value from each investment.

Extending equipment lifespans directly reduces electronic waste, advancing circular economy goals. Current consumer behaviour—frequent upgrades driven by aesthetic or minor functional improvements—creates unsustainable waste. A shift toward thoughtful procurement and longer use cycles can help mitigate this issue significantly.

Sustainability must also be embedded at the manufacturing level. Organizations and consumers alike should advocate for durable, repairable, and upgradeable products that align with environmental and social goals. Such practices foster sustainable consumption without compromising on quality or performance.

Adopting Green IT is not as complex as it may initially seem. Incremental steps—such as prioritising energy efficiency, extending product use, reducing e-waste, and embracing renewable energy—can collectively drive meaningful progress. By making informed choices, both individuals and organisations can extend the value of technology while supporting long-term sustainability.
