Rethinking Decarbonization and Circularity in India’s Urban Infrastructure

P. GopalaKrishnan, Managing Director – SAME, Green Business Certification Inc. (GBCI), looks at why decarbonisation and circularity must become central to infrastructure decisions shaping the country’s urban future.

India’s next infrastructure decade is being built at an uncommon speed and scale and under uncommon climate pressure. The Union Budget’s capital expenditure outlay for FY 2024–25 was set at ₹11,11,111 crore, signaling sustained investment in infrastructure. At the same time, the demographic centre of gravity continues to shift: ≈35% of India’s population was urban in 2024, with cities absorbing most new demand for mobility, housing and services. The World Bank has underlined what this implies for financing and delivery capacity, estimating that more than $2.4 trillion will be needed by 2050 for resilient, low-carbon urban infrastructure.

This collision of growth and climate reality reframes the built environment agenda. India’s climate commitments, such as the updated Nationally Determined Contribution target of reducing emissions intensity of GDP by 45% by 2030 (from 2005 levels), cannot be met by operational efficiency alone. Nor can urban resilience be treated as an incremental add-on when heat, flooding, and resource stress impact the performance and life-cycle cost of assets. This shift demands a move beyond fragmented sustainability interventions toward system-level thinking—where infrastructure is designed and delivered as an integrated, low-carbon and resource-efficient network.
