Carbon-neutral by design: Rethinking digital infra

India's data centre growth must align with climate goals—building for sustainability from day zero is now a digital and environmental imperative.

The world runs on digital.

From boardroom strategy to the shows people stream, a cloud-first reality is no longer a futuristic concept-it is already there. Digital public infrastructure is now seen as the bedrock of economic growth. Amid the never-ending excitement for digital-first products and solutions, the question now is: can the industry also build responsibly and sustainably? The answer is yes. But it requires discarding the old rulebook.

Every click, every search, and every Al query is powered by data centres, which are massive, energy-hungry facilities that are the hidden giants of the digital age. Reports indicate that power consumption by data centres globally is around 2-3% of total electricity consumption in the world. This accounts for more than the annual energy consumption of many countries.

With Al workloads increasing by the day, this number is set to climb sharply. As a growing hotspot for data centres, India's facilities could soon account for 8% of the country's total electricity usage. In this context, integrating sustainability thinking into every layer of digital infrastructure will no longer be optional; it will be essential to ensure long-term resilience, efficiency, and environmental responsibility.
