What Is Green IT?
Green IT (also called sustainable IT or green computing) refers to designing, using and disposing of computing equipment and services in ways that reduce their environmental impact — energy consumption, e-waste, and carbon emissions from data centres and devices. It covers everything from how hardware is manufactured to how a business retires old equipment.
Common Green IT Practices
Common practices include consolidating servers through virtualisation so fewer physical machines are needed, choosing energy-efficient hardware and data centre cooling, enabling power management settings on office devices, extending device lifespans through good maintenance instead of frequent replacement, and responsibly recycling e-waste rather than sending it to landfill. Moving workloads to cloud providers that run large, efficient data centres can also reduce a business's own energy footprint.
Why It Also Makes Business Sense
Beyond the environmental case, Green IT practices tend to lower operating costs directly — less power draw, fewer cooling requirements, and hardware that lasts longer before needing replacement. For businesses under growing pressure from customers, investors and regulators to report on sustainability, IT is often one of the more measurable and improvable parts of the overall footprint.
