India will require an estimated USD 1.5 trillion in investment by 2030 to effectively address climate change across critical sectors, according to a report by Deloitte India.

The report, titled "The Climate Response: Tapping into India’s Climate and Energy Transition Opportunity", highlights the country's urgent need to invest in renewable energy, biofuels, decarbonisation, and sustainable infrastructure.

Key areas identified for investment include water security, sustainable agriculture, low-carbon transport, circular economy initiatives, waste management, and digital platforms. These sectors will drive India’s broader climate and energy transition strategy.

To reach the target of 500 GW of renewable energy (RE) capacity by 2030, India must add 300 GW to its existing capacity, which alone will demand an investment of around USD 200–250 billion. This includes funding for advanced manufacturing, grid integration, and transmission expansion.

Additionally, scaling up energy storage infrastructure by eight times will be necessary to support RE growth, requiring capital expenditure of approximately USD 250–300 billion by FY30.

Viral Thakker, Partner and Sustainability and Climate Leader at Deloitte South Asia, stated that these investments would not only cut emissions but also generate employment, strengthen energy security, and safeguard vulnerable communities against climate risks.

He further noted the importance of financial mechanisms such as green bonds, climate funds, and blended finance to unlock capital for sustainability projects. Ensuring broad and equitable access to climate finance will be essential for building long-term resilience across India's most climate-sensitive sectors.
