Better roads can help India connect workers, businesses and markets, but they cannot by themselves reproduce China’s economic transformation. And if road investment simply locks in more energy-intensive travel, it will make the climate task harder. India can pursue growth and its 2070 net-zero goal together only through a wider transport strategy: roads planned for access and resilience, alongside cleaner vehicles, public and shared transport, rail and waterways.
How roads can support economic growth
Roads can make places and markets more reachable. For businesses, more reliable connections can reduce logistics friction; for workers and households, they can improve access to jobs, services and customers. The gains depend on where links go, how reliable and safe they are, and whether they connect with other modes rather than operate as isolated corridors.
NITI Aayog says multimodal networks can reduce logistics costs and strengthen export competitiveness. Its commentary also attributes an estimated public-infrastructure spending multiplier of 2.5–3.5x to studies by the Reserve Bank of India and NIPFP. That is a figure about public infrastructure spending as cited in the commentary—not a road-specific multiplier or a guarantee that each project will produce the same return.

What the Golden Quadrilateral evidence shows—and does not show
NITI Aayog’s 2026 transport report says manufacturing output in districts within 10 km of the Golden Quadrilateral rose by nearly 49% in the years following the network’s implementation. This is evidence of a substantial outcome near that network; it does not establish that roads alone caused the increase, that the effect applies to every road project, or that road building alone can generate national economic transformation.

Why the China comparison is a question, not a proven recipe
The analogy is useful as a prompt to examine how infrastructure supports markets, but the available evidence does not provide a directly comparable causal estimate showing that Indian road investment can reproduce China’s aggregate growth experience. A historical association between infrastructure and growth is not proof that highway mileage alone caused a country’s transformation or that the same formula will work in another economy.
For India, the more useful question is whether each investment expands access and improves the movement of people and goods at reasonable social and environmental cost. That means assessing connectivity, reliability, logistics, safety, affordability and the role of rail and waterways—not treating total road construction as the sole measure of progress.

India’s transport system has a significant energy and emissions challenge
In NITI Aayog’s account, transport produced around 10% of India’s national greenhouse-gas emissions and used 20% of final energy demand in 2020. Its report estimates that in 2025 roads carried about 78% of passenger traffic and 66% of freight traffic in India. Those dated estimates show why transport choices matter: a road network can improve access, but a road-dominant system also makes the way vehicles are powered and trips are planned consequential. NITI Aayog’s 2026 transport report
The same report estimates waterways carried about 8% of freight movement in India, compared with about 25% in China in 2025. The figures describe different national transport mixes; they do not by themselves establish that shifting a specific Indian shipment to waterways is feasible or beneficial. They do, however, underline why a growth strategy need not mean putting every passenger or tonne on a road journey.
What a net-zero-compatible transport pathway entails
India’s stated economy-wide net-zero goal is 2070. NITI Aayog’s 2026 transport analysis models scenarios that are consistent with that goal; the results are conditional scenario outputs, not forecasts or a guarantee that current policies will deliver them. India’s Long-Term Low Emission Development Strategy NITI Aayog’s 2026 overview of the scenarios
In the report’s 2070 comparison, its Net Zero Scenario (NZS) relies on lower transport energy demand and a different mix of modes than its Current Policy Scenario (CPS):
| Modelled 2070 measure | Current Policy Scenario (CPS) | Net Zero Scenario (NZS) |
|---|---|---|
| Transport energy demand | 336 Mtoe | About 200 Mtoe |
| Public and shared modes’ share of passenger trips | 50% | About 60% |
| Rail’s share of freight | 25% | 30% |
These are the report’s modelled outcomes for the two specified scenarios, not measured results or adopted transport-sector targets. The gap between them illustrates that the net-zero pathway is not just a matter of building greener highways: it also depends on vehicle and fuel changes, more public and shared mobility, and a greater role for rail.

Separate the impact of building roads from the impact of using them
Road projects have two distinct climate questions. The first is how construction and infrastructure design affect materials, durability, safety and vulnerability to climate risks. The second is the energy and emissions associated with vehicles using the network, and how demand or travel shifts across modes.

- Access: Does a project connect people and businesses to jobs, markets and services that were difficult to reach?
- Logistics: Does it improve travel time and reliability, and link effectively with rail, ports or waterways where appropriate?
- Mode and demand: Does planning account for passenger and freight needs, public and shared travel, and the possibility that a new link changes how much or how people travel?
- Lifecycle effects: Are construction materials, durability and climate resilience considered alongside the energy and emissions of vehicles using the road?
- Distribution and safety: Who gains access, who bears project costs, and are routes designed to improve safety and affordability?
- Evidence: Is a claim based on an observed local outcome, a modelled scenario or a policy ambition? Those forms of evidence should not be treated as interchangeable.
Applied this way, roads are one part of a transport system rather than a substitute for one. India’s 2070 net-zero goal can coexist with road investment if connectivity supports inclusive growth while transport energy and emissions are managed across modes and over the life of infrastructure.
