According to NITI Aayog, India must decarbonise its transport sector to achieve its Net Zero 2070 goal. The report highlights that the transport sector contributes nearly 20% of India’s final energy demand and around 10% of total greenhouse gas (GHG) emissions as of 2020. Therefore, transforming this sector is essential for India’s climate commitments, energy security, and sustainable development.
For UPSC, APSC, APPSC, and other State PCS aspirants, this topic is highly important. It comes under Environment & Ecology, Indian Economy, Infrastructure, Climate Change, and Government Policies.
Aspirants studying climate change, economy, and infrastructure can rely on expert guidance from UPSC coaching in Assam.
Why Is the Transport Sector Crucial for India?
The transport sector plays a vital role in India’s economic growth. It supports trade, industry, urban mobility, and logistics. However, it also increases fuel consumption and carbon emissions.
Key Concerns Highlighted in the NITI Aayog Report:
- The sector accounts for 20% of final energy demand.
- It contributes around 10% of greenhouse gas emissions.
- Rapid urbanisation is increasing travel demand.
- Dependence on fossil fuels raises fuel imports and energy insecurity.
- Poor air quality in cities worsens public health.
Therefore, if India continues under the Current Policy Pathway, emissions will rise sharply. This could lock the country into higher fuel imports, rising logistics costs, and environmental degradation.
Net Zero Pathway: Investment Requirement
According to NITI Aayog, implementing the Net Zero pathway will require approximately USD 4.3 trillion in cumulative investment till 2070.
In comparison, the Current Policy pathway requires about USD 3.44 trillion.
Although the additional investment appears high, the report clearly states that it is not merely a cost burden. Instead, it is a strategic opportunity to modernise infrastructure, create green jobs and enhance long-term economic resilience.
What Does “Decarbonising Transport Through Modal Shift” Mean?
Understanding Modal Shift:
A modal shift refers to shifting transportation from high-emission modes (such as private vehicles and road freight) to low-emission and energy-efficient modes like:
- Metro rail systems
- Regional Rapid Transit System (RRTS)
- Public buses
- Rail-based freight transport
- Non-motorised transport (cycling and walking)
By promoting modal shift, India can significantly reduce emissions while improving efficiency.
Key Strategies Recommended by NITI Aayog:
1. Promote Zero-Emission Vehicles (ZEVs)
NITI Aayog strongly recommends increasing the adoption of Zero-Emission Vehicles (ZEVs), including:
- Battery Electric Vehicles (BEVs)
- Hydrogen-based vehicles
- Ethanol-based Flex Fuel Vehicles (FFVs)
- Compressed Bio-Gas (CBG) vehicles
These technologies reduce dependence on fossil fuels and lower greenhouse gas emissions.
2. Expand Public Transport Infrastructure
The report suggests expanding:
- Metro networks
- Regional Rapid Transit Systems (RRTS)
- Bus transport systems
- Last-mile connectivity solutions
- Formalised paratransit integration
All these can reduce congestion, lower fuel consumption, and improve urban air quality.
3. Improve Freight Efficiency
India must shift freight transport from roads to railways and waterways wherever possible. Rail and water transport produce lower emissions compared to road transport.
Efficient logistics systems can reduce fuel consumption, lower logistics costs and improve supply chain sustainability.
4. Advance Clean Fuel Diversity
The report emphasises promoting biofuels, green hydrogen, renewable electricity and sustainable aviation fuels. Similarly, decarbonising aviation and shipping sectors are equally important because these sectors are hard-to-abate industries.
Industrial Sector Transition and Developed Nation Goal:
As India aims to become a developed nation, its industrial sector must transit toward cleaner technologies. According to NITI Aayog, this requires:
- Technology upgrades
- Electrification of processes
- Adoption of renewable energy
- Resource efficiency
- Innovative financing mechanisms
- Supportive policy frameworks
- Capacity building for MSMEs
This integrated approach will help India achieve sustainable growth while reducing carbon intensity.
Why Modal Shift Is a Strategic Opportunity:
Rather than viewing decarbonisation as an economic burden, policymakers consider it a long-term strategic advantage.
Benefits of Modal Shift and Zero Emission Vehicles (ZEV) Adoption
- Reduced fuel imports and improved energy security.
- Lower air pollution and better public health.
- Creation of green jobs.
- Reduced logistics costs.
- Increased investment in clean technologies.
- Enhanced global competitiveness.
Moreover, investing in sustainable transport systems strengthens India’s commitment under international climate agreements.
Challenges in Decarbonising the Transport Sector:
Despite the benefits, India faces several challenges:
- Firstly, the high upfront cost of electric vehicles (EVs) remains a major barrier for widespread adoption. Even though operational costs of EVs are lower over time, the initial purchase price is still higher than conventional internal combustion engine vehicles. As a result, many consumers hesitate to shift to cleaner alternatives despite government incentives.
- Secondly, the limited availability of charging infrastructure significantly restricts EV expansion. In many cities and rural areas, charging stations are either insufficient or unevenly distributed. Consequently, range anxiety continues to discourage potential buyers from adopting electric mobility solutions.
- Moreover, technological barriers in hydrogen adoption pose another serious challenge. While hydrogen-based vehicles hold long-term potential, the technology is still evolving. In addition, the production, storage, and transportation of green hydrogen require advanced infrastructure and high investment, which are currently at a developing stage.
- Furthermore, financing gaps hinder the expansion of public transport systems such as metro rail, Regional Rapid Transit Systems (RRTS), and electric bus networks. Large-scale infrastructure projects demand significant capital investment, and many state governments face budgetary constraints that delay implementation.
- In addition, behavioural resistance among citizens affects modal shift efforts. Many commuters prefer private vehicles due to convenience, comfort, and flexibility. Therefore, changing travel habits requires not only infrastructure development but also sustained public awareness and behavioural change campaigns.
Given these challenges, the government must adopt a comprehensive strategy. This strategy should combine financial incentives, infrastructure expansion, technological innovation, and policy support. At the same time, it should strengthen public awareness campaigns to promote sustainable mobility choices and encourage citizens to actively participate in India’s transition toward a low-carbon transport system.
Conclusion: Decarbonise Transport Sector for Net Zero 2070
The recent NITI Aayog report on decarbonising the transport sector through modal shift clearly identifies a transformative pathway for achieving India’s Net Zero 2070 target. The report estimates that the Net Zero pathway will require nearly USD 4.3 trillion in cumulative investment by 2070. However, this investment should not be viewed merely as an additional financial burden. Instead, it represents a strategic opportunity to modernise transport infrastructure, reduce greenhouse gas emissions, strengthen energy security, and drive long-term sustainable economic growth.
By promoting modal shift, expanding public transport networks, and accelerating the adoption of zero-emission vehicles, India can reduce its dependence on fossil fuels. Through this, India can improve urban air quality and logistics efficiency. At the same time, investments in clean technologies such as battery electric vehicles (BEVs), hydrogen vehicles, and biofuels will position India as a key player in the global green economy.
