Enhancing Environmental Infrastructure in Urban India

India’s cities are growing at a pace few countries have ever witnessed. India’s urban population is projected to surge from 377 million in 2011 to 590 million by 2030, creating an enormous and urgent demand for housing, energy, and transport infrastructure. Yet the systems meant to meet these needs – land markets, energy utilities, and public transport networks – are struggling to keep up. The result is a widening gap between what Indian cities need and what they currently provide, with real consequences for millions of urban residents.

The urban housing crisis: a market that isn’t working

At the heart of India’s urban infrastructure problem lies a deeply dysfunctional housing market. The urban housing shortage stood at 18.78 million houses for the period 2012-2017, with 95 percent of this gap concentrated among low-income households. Meanwhile, there are an estimated 11 million vacant homes across urban India – an irony that points not to a shortage of buildings, but to a failure of access and affordability.

The root cause is structural. Land-use plans cannot keep pace with rapid urban population growth, which leads to the expansion of slums and prevents their rehabilitation – a process mired in insecure land tenures, litigation, and land locked off the market. Restrictive building regulations such as low Floor Area Ratio (FAR) limits, arbitrary setback rules, and building height restrictions compound the problem by artificially constraining supply in areas where demand is highest.

The urban poor are hit hardest. As per the 2011 Census, approximately 108,000 slums exist across the country, home to 13 million households, of which 3.6 million are renters. Conditions within these settlements are stark: 71 percent of slums have no access to underground sewerage, and 41 percent have either dry-pit latrines or no latrine facilities at all. The problem is not simply one of numbers – it is about the quality and security of shelter.

Why policy responses have fallen short

India has launched several ambitious housing programmes over the decades – from the Jawaharlal Nehru National Urban Renewal Mission (JNNURM) to the Rajiv Awas Yojana and, more recently, the Pradhan Mantri Awas Yojana-Urban (PMAY-U). Ever since the first National Housing Policy in 1988, the government has tried to reform the housing and real estate sector, yet many affordable housing schemes have underachieved.

A recurring pattern explains this underperformance. Many early schemes failed because resettlement solutions were often unacceptable to beneficiaries – housing was located far from city centres and places of employment – and there was a complete absence of community participation in their design. Housing units built under subsidised schemes were frequently abandoned because residents could not afford the associated costs of maintenance, utilities, and property tax. India’s housing strategy must move beyond merely creating affordable stock; it must correct the market distortions and structural anomalies that make formal housing unnecessarily expensive.

The demand for land reform is especially critical. Fragmented ownership records, multiple public-sector entities holding large land parcels (railways, ports, urban local bodies), and outdated rent control laws together keep vast stretches of potentially developable urban land out of productive use. Large-scale urban developments are becoming increasingly difficult due to a lack of available land, congested transport routes, a lack of finance, rising costs, and regulatory hurdles.

Urban energy: consumption, monopoly, and the push for efficiency

Housing is inseparable from energy. As Indian cities grow denser and hotter, the energy consumed by buildings – for cooling, lighting, and appliances – is rising sharply. More than 50 percent of India’s building stock expected to exist by 2030 is yet to be built, which means the country has an extraordinary opportunity to design energy efficiency into new construction from the outset, rather than retrofitting aging stock later.

India’s policy framework for energy-efficient buildings has gradually expanded. The Energy Conservation Building Code (ECBC) sets energy efficiency standards for commercial buildings, and the Eco Niwas Samhita extends similar requirements to residential construction. While 22 states have mandated the ECBC, actual compliance monitoring remains uneven – smaller cities and tier-2 towns, where much of India’s future construction will happen, need greater capacity-building and financial support to adopt green building practices.

The energy sector itself has historically operated under government monopolies, with state electricity boards controlling generation and distribution. This structure has often resulted in cross-subsidisation, inefficient pricing, and limited incentive for utilities to invest in modernisation. While electricity distribution has seen some reform through private participation in cities like Delhi and Mumbai, the broader grid remains heavily reliant on fossil fuels. India must invest US$ 4.5 trillion in infrastructure to enhance economic growth and societal well-being, and a significant share of this must go toward clean energy transitions.

Decentralised energy and the solar shift

One promising development is the move toward decentralised energy systems. A pilot net-zero district in Delhi integrated rooftop solar arrays, battery storage, demand-responsive buildings, and localised distribution networks – transforming energy from an invisible utility into a spatial system embedded within the district’s architecture. This approach signals a broader shift: energy planning is no longer just an engineering problem but an urban design challenge.

India’s mandatory star-rating system for household appliances is another practical lever that has demonstrated results. By making energy savings visible and financially compelling at the consumer level, it has encouraged the uptake of energy-efficient products across income groups. Public education campaigns, real-time energy monitoring apps, and incentives for energy-efficient appliances can drive behavioural changes that lower household carbon and water footprints. Cities like Pune are also progressing: Pune aims to increase renewable energy usage by 50 percent by 2030, with the Maharashtra government offering incentives like additional Floor Area Ratio for projects achieving green building certifications.

Urban transport: the congestion crisis and the sustainable alternative

Transport is where the strain on Indian urban infrastructure becomes most visible. Indian cities are among the most congested in the world. A review of comprehensive mobility plans revealed that the average motor vehicle speed on urban roads was merely 15-16 km/h, and Bengaluru ranked as the city with the worst global traffic congestion, with Mumbai, Pune, and New Delhi following closely. The problem is compounded by the fact that on-street parking occupies up to 60 percent of road width in many Indian cities.

The environmental cost is substantial. Urban transport infrastructure accounts for 23 percent of global energy-related CO₂ emissions, 64 percent of world oil use, and 27 percent of all energy consumption. In India specifically, road transport was responsible for 14 percent of the nation’s total energy consumption in 2021, and 94 percent of transport-related CO₂ emissions. Without intervention, these figures will worsen as private vehicle ownership rises alongside incomes.

Policy reforms and the shift to sustainable mobility

India’s policy stance on urban transport has gradually shifted from simply building more roads to managing demand and promoting low-carbon alternatives. The National Urban Transport Policy (NUTP), first launched in 2006 and revised in 2014, paved the way for large-scale reforms, envisioning and launching schemes on sustainable transportation such as the Bus Rapid Transit System (BRTS), light rail projects, and mass rapid transport systems.

The electrification of public transport has emerged as a key priority. The National Electric Bus Programme (NEBP) aims to deploy 50,000 e-buses across Indian cities by 2030, while metro systems in Delhi, Bengaluru, Pune, and Hyderabad are expanding rapidly, offering clean alternatives to car-based commutes. The PM e-Bus Sewa scheme, announced in 2023, targets 10,000 electric buses across 100 cities using a public-private partnership model.

However, electrification alone is not enough. Research by ITDP and the University of California, Davis finds that only compact planning and electrification together can effectively limit India’s transport-related emissions – neither strategy is sufficient on its own. This means urban planning must change as well: cities need to be designed so that people can walk, cycle, or take short public transit trips to reach work, schools, and services – reducing the need for long motorised commutes in the first place.

Integrating infrastructure: the missing link

One of the most persistent weaknesses in India’s urban environmental infrastructure is the lack of integrated planning. Housing policy, energy policy, and transport policy have typically been developed in separate institutional silos, leading to outcomes that undermine each other. Affordable housing built far from transit corridors forces residents into car dependency. Energy planning that ignores building design results in inefficient stock that cannot be easily upgraded. Transport investments made without considering land use generate induced demand rather than solving congestion.

Integrated planning – coordinating across sectors like housing, transportation, energy, and waste management – is essential to maximise efficiency and sustainability. The Smart Cities Mission, launched in 2015, attempted to promote this kind of cross-sectoral coordination in 100 cities, and since its inception, annual assessments have been conducted, aiming to promote low-carbon development, deploy energy-efficient technologies, and invest in climate-resilient infrastructure at the local level.

The World Bank’s report Towards Resilient and Prosperous Cities in India estimates that with India’s urban population expected to nearly double by 2050 to 951 million, more than 144 million new homes will be needed by 2070 – an investment challenge of historic proportions. The same report finds that timely adaptation can avert billions of dollars in annual losses from weather-related shocks, including up to $30 billion annually in flood-related damage by 2070.

Finance, governance, and the private sector

Meeting India’s urban infrastructure needs will require not just policy reform but a fundamental shift in how this infrastructure is financed. Governments can establish green infrastructure funds in partnership with banks and private equity investors, providing low-interest loans for sustainable construction projects, while the private sector drives innovation in low-carbon building materials, IoT-enabled energy monitoring, and efficient HVAC systems.

Urban local bodies (ULBs) in India remain chronically under-resourced, with limited capacity to plan, finance, or oversee complex infrastructure projects. Strengthening their technical and financial autonomy is a precondition for any meaningful improvement. Cities that have demonstrated success in sustainable transformation – like Surat’s shift from a plague-affected city to a model of urban management – have invariably benefited from consistent political support and institutional strengthening. The lesson is clear: good infrastructure requires good governance.

India’s urban environmental infrastructure challenge is ultimately a question of whether the country can build differently from how it has built before – more equitably, more sustainably, and with a long view. With 70 percent of India’s built environment for 2030 yet to take shape, there is still time to get the fundamentals right – but the window is narrowing with each year of uncoordinated growth.

What do you think? Can India’s urban local bodies realistically lead integrated housing, energy, and transport planning without deeper structural reforms in governance and finance – or does change need to be driven from the top down? And as Indian cities expand rapidly, which dimension of environmental infrastructure – housing, energy, or transport – deserves the most urgent policy attention, and why?
