New Delhi: With 'Green IT' and sustainable development becoming top priorities for businesses in the country, India's spending on green IT and sustainability initiatives is set to double to USD 70 billion in 2015, research firm Gartner said.

In a report titled, 'Hype Cycle for Green IT and Sustainability in India, 2011," analysts said Green IT and sustainability initiatives have already found their way into the IT roadmap of many industries in India.

Although still buzzwords for many, they will soon emerge as top priorities for businesses, investors and technology professionals across industries and policymakers in India, it added.

The report pegged spending on green IT and sustainability initiatives at USD 35 billion in 2010.

"India's information and communication technology (ICT) industry will be an early adopter of green IT and sustainability solutions, as India is one of the fastest-growing markets in terms of IT hardware and communications infrastructure consumption," Gartner Research Director Ganesh Ramamoorthy said.

In addition, the banking and financial services, hospitality, manufacturing (such as automobiles), pharmaceuticals and other industries that have significant exposure to export markets, will also make an early jump on to the green IT and sustainability bandwagon in India.

"Indian businesses will initially start adapting solutions that have been tried and tested in developed nations, but tailored to the Indian market's needs and conditions," Ramamoorthy said.

However, the unique challenges faced by India, such as unreliable power infrastructure, the growing urban-rural divide and increasing population migration to urban areas will also provide businesses with the opportunity to innovate and test new cost-effective approaches and green technology solutions, he added.
