Freight Electrification · LogisticsRail Versus Road: The Modal Shift Decision for India’s Industrial Shippers and What Supply Chain Decarbonisation Means for Logistics Strategy
India’s electrified rail network emits 11.5 grams of CO₂ per tonne-km against 101 grams for road freight — an 89% reduction in transport carbon intensity confirmed by the Ministry of Railways citing NITI Aayog data. Rail also costs Rs 1.96 per tonne-km against Rs 3.78 for road, according to the September 2025 DPIIT-NCAER study — the first systematic measurement of India’s logistics costs, which pegged the total burden at 7.97% of GDP or approximately Rs 24 lakh crore annually. The break-even for multimodal transport over pure road is approximately 600 km with first-and-last-mile road legs of 50 km each. Above that distance, rail is cheaper on pure freight cost. For the industrial routes that matter most — steel from Odisha to Gujarat, cement from Rajasthan to Maharashtra, fertiliser from Andaman-linked coastal terminals to inland plants — the cargo distances are 600 to 1,500 km, firmly within rail’s economic zone. Yet road carries approximately 65 to 70% of India’s freight. This article maps the cost and carbon arithmetic of the modal shift decision, what the Dedicated Freight Corridors change about the calculus, and why supply chain emissions are becoming a real commercial pressure on industrial logistics planners through BRSR, CSRD-driven buyer requirements, and long-term CBAM expansion risk.
India’s freight logistics cost was measured at 7.97% of GDP — approximately Rs 24 lakh crore — in the DPIIT-NCAER September 2025 report, the first systematic bottom-up measurement of this figure. The previously cited 13 to 16% estimate is now superseded. The modal cost comparison: rail Rs 1.96 per tonne-km (excluding first/last-mile); road Rs 3.78 per tonne-km; waterways Rs 1.80 per tonne-km; air Rs 72 per tonne-km. Road freight is approximately 93% more expensive than rail per tonne-km on a pure line-haul basis. But road provides door-to-door connectivity, flexibility for partial loads, and shorter transit times on short hauls — advantages that explain why it continues to dominate despite the cost and carbon disadvantage.
Rail’s CO₂ emission intensity is 11.5 g per tonne-km against road’s 101 g per tonne-km — confirmed by Ministry of Railways citing NITI Aayog’s Fast Tracking Freight in India report. This 89% emission advantage has been transformed in recent years by Indian Railways’ electrification programme, which reached 99.4% of the broad-gauge network by early 2026 — ahead of the UK (39%), Russia (52%), and China (82%). Electrification allows rail to progressively decarbonise as the electricity grid greens; India’s grid emission factor is falling year on year as renewable capacity additions accelerate. A 1,000-tonne steel shipment over 1,000 km by road emits approximately 101 tonnes of CO₂; the same shipment by rail emits approximately 11.5 tonnes — a saving of 89.5 tonnes CO₂ per movement.
The break-even distance for multimodal (rail plus road) over pure road is approximately 600 km assuming 50 km first-mile and last-mile road legs on each side. If first/last-mile legs extend to 100 km each, the break-even shifts to approximately 1,000 km. The most important industrial freight corridors in India — steel from eastern producing states to consumption centres, cement from Rajasthan-Gujarat to Maharashtra-South India, fertiliser from coastal terminals to inland warehouses — are predominantly in the 600 to 1,500 km range. These are routes where rail is already economically competitive on pure cost terms without any carbon pricing. The DFCs improve rail’s competitiveness further by raising average freight speed from approximately 25 to 30 km/h on legacy lines to 50 to 60 km/h on dedicated corridors — directly reducing inventory carrying costs and transit time risk for time-sensitive industrial cargoes.
Supply chain emissions are becoming a commercial consideration for industrial shippers through three channels. First, India’s BRSR framework (mandatory for top 1,000 listed companies) requires disclosure of Scope 3 emissions, which includes both upstream and downstream transport. Second, EU-based buyers under the Corporate Sustainability Reporting Directive are required to disclose and reduce Scope 3 emissions, which reaches back into Indian supplier freight decisions. Third, there is a long-term risk that CBAM’s scope expands to include embedded transport emissions — not currently in scope, but analytically consistent with CBAM’s objective of equalising full life-cycle carbon costs. For a steel plant exporting to the EU, the embedded production emission is large and CBAM-exposed. Embedded freight emission is currently exempt — but international policy trends suggest this exemption may not be permanent.
The Ministry of Railways introduced a simplified flat-rate tariff of Rs 0.90 per tonne per km for bulk cement transportation in FY2025-26, improving cost predictability and removing a historical barrier to cement modal shift. RORO (Roll-On Roll-Off) services — trucks loaded onto rail wagons for the DFC corridor transit — recorded 545 rakes in April to December 2025, providing a seamless solution for shippers who cannot or do not want to repackage cargo for rail wagons. Together with 25 Gati Shakti Cargo Terminals commissioned in FY2025-26, these operational changes reduce the practical friction of choosing rail, particularly for smaller consignments and door-to-door industrial shipments.
The numbers — cost and carbon per tonne-km, mode by mode
The DPIIT-NCAER September 2025 logistics cost study — India’s first systematic bottom-up measurement of freight costs — established the per-tonne-km figures that now anchor any honest modal comparison in the country. The study found logistics costs of 7.97% of GDP, significantly below the previously cited 13 to 16% figures that had shaped policy discussions for years. That revision matters for policy: a 7.97% burden is still high by global standards (Germany 8%, Japan 11%), but closer to the range where targeted modal improvements rather than wholesale infrastructure overhaul are the right response.

The cost comparison requires one important qualification. The Rs 1.96 per tonne-km for rail excludes first-mile and last-mile road legs — the truck movements between the plant and the rail siding, and between the receiving siding and the consumption point. When these are added at road costs, the total multimodal price rises. The DPIIT-NCAER study confirmed that with 50 km road legs at each end, rail-based multimodal beats pure road transport beyond 600 km. With 100 km road legs at each end, the break-even extends to approximately 1,000 km.
The heavy trailer comparison is worth noting. Very large road vehicles — trailers above 55 tonnes gross vehicle weight — operate at Rs 1.51 per tonne-km on the line-haul segment, below rail’s Rs 1.96. But this figure excludes the cost of operating at India’s actual road conditions (overloading penalties, state toll variations, highway congestion), and it does not include the full door-to-door cost when handling fees, waiting times, and multiple transshipment points are counted. For bulk industrial cargo — coking coal, iron ore, steel slabs, cement clinker, fertiliser — rail’s scale economy and terminal infrastructure advantages become decisive beyond the break-even distance.
The 89% carbon advantage — and why it matters for industrial supply chains now
The 11.5 g versus 101 g CO₂ per tonne-km comparison is not an academic abstraction — it is directly relevant to the Scope 3 emissions that India’s large listed companies must now disclose under BRSR. For a steel plant that dispatches 3 million tonnes of finished steel per year over an average distance of 1,000 km, the difference between road and rail as the primary freight mode is enormous in absolute carbon terms.
(3 Mt × 1,000 km) 3 billion tonne-km 3 billion tonne-km
(excluding first/last mile) ~Rs 1,134 crore/year ~Rs 588 crore/year
The 268,500 tCO₂ annual savings from this single modal shift is a material Scope 3 reduction that would appear directly in the company’s BRSR disclosure and its CDP supply chain carbon report. For a company whose production Scope 1 and 2 emissions are in the range of 7 to 8 million tCO₂ per year (at 2.5 tCO₂/t for BF-BOF on 3 Mt output), the transport Scope 3 represents approximately 4% of total operational carbon footprint. Eliminating it through modal shift is significantly cheaper than any production-level abatement at equivalent scale.
The cost saving of approximately Rs 546 crore per year on freight expenditure alone — before any carbon pricing is applied — makes modal shift a financially rational decision on pure logistics economics for hauls above 600 km. For a company that has historically used road freight due to flexibility and scheduling convenience, the DFCs change the transit time picture substantially: average freight speed on the DFCs is 50 to 60 km/h, against 25 to 30 km/h on legacy mixed-use railway lines. A shipment from Odisha to Gujarat — approximately 1,600 km — takes approximately 27 to 32 hours by DFC against 53 to 64 hours on legacy rail or 60+ hours by road including toll stops and rest time. The transit time gap has narrowed to the point where DFC rail is genuinely competitive with road for time-sensitive industrial consignments.
Sector-specific break-even analysis — steel, cement, and fertiliser
| Industrial sector | Key freight corridors | Typical distance | Rail viable? | Rail vs road CO₂ saving per year (illustrative) | Key barrier to modal shift |
|---|---|---|---|---|---|
| Steel (slab, HRC, rebar) | Odisha / Jharkhand → Gujarat / Maharashtra / North India Chhattisgarh → Southern states | 700–1,800 km | Strongly viable | For 1 Mt steel over 1,200 km avg: ~107,000 tCO₂/year saved by modal shift to rail | Siding availability at plant; wagon availability; transit reliability for JIT delivery schedules |
| Cement (clinker, bagged cement) | Rajasthan → Maharashtra / Gujarat Andhra Pradesh / Telangana → Karnataka / Tamil Nadu | 500–1,200 km | Viable above 600 km; new flat-rate tariff Rs 0.90/t-km helps | Rail’s flat-rate tariff of Rs 0.90/tonne-km for bulk cement (introduced FY2025-26) now gives predictable costing. Key barrier: wagon supply for high-volume dispatch at short notice; seasonal demand spikes | Wagon availability during peak seasons; last-mile from rail sidings to construction sites (typically road) |
| Fertiliser (urea, DAP, MOP) | Kandla / Mundra / Ennore ports → inland states Gas-based urea plants to distribution warehouses | 400–1,500 km | Partially viable; many movements already on rail via rake system | Indian Railways’ rakes are already the dominant mode for government-subsidised fertiliser distribution. Key gap: private non-subsidised fertiliser and NBS products face more complex logistics | Rake availability during sowing season; first-mile from port to siding; 50 kg bag handling at last mile |
| Aluminium (ingot, wire rod, rolled) | Odisha / Chhattisgarh → Mumbai / Gujarat export terminals; auto cluster states | 800–1,400 km | Viable; premium products increasingly in containers on DFC | Container rail on DFC now available; allows aluminium in coil or ingot form without wagon-specific loading. DFC transit time improvement is significant for export-oriented smelters | Port connectivity for DFC container trains; container availability at inland origins |
The cement sector modal shift is particularly notable because of the Ministry of Railways’ FY2025-26 intervention: a simplified flat-rate tariff of Rs 0.90 per tonne per km for bulk cement, replacing the complex freight rate structure that had historically made cement rail costing unpredictable. This single policy change — confirmed in the Ministry of Railways Year-End Review for 2025 — addresses a key complaint from cement producers that rail’s tariff complexity made long-term logistics planning difficult. Combined with the WDFC’s direct connection between key cement-producing clusters in Rajasthan and consumption centres in Maharashtra and Gujarat, the modal shift case for cement has materially improved.
Roll-On Roll-Off (RORO) services allow fully laden trucks to be driven onto specially designed railway wagons and transported via the Dedicated Freight Corridors without any cargo handling or repackaging. At the destination, the truck drives off and completes last-mile delivery. RORO eliminates the single biggest operational barrier to modal shift for many industrial shippers — the need to transship cargo at the rail origin and destination, which adds handling cost, transit risk, and time. RORO recorded 545 rakes in April to December 2025, generating Rs 36.95 crore in revenue. Users include Amul (dairy cargo maintaining cold chain integrity) and general cargo shippers. For steel service centres, chemicals shippers, and automotive component manufacturers who have invested in specific truck body configurations, RORO provides DFC access without any modification to their existing logistics model. As RORO rakes and terminals scale, the operational friction of modal shift for these categories reduces significantly.
Supply chain emissions as a commercial pressure — beyond voluntary disclosure
The carbon case for modal shift has historically been relevant mainly for voluntary sustainability reporting and CSR communications. Three developments are now making it a commercial pressure point for Indian industrial shippers with significant EU market exposure.
BRSR Scope 3 disclosure. India’s Business Responsibility and Sustainability Reporting framework, mandatory for the top 1,000 listed companies by market capitalisation, requires disclosure of Scope 3 emissions including upstream and downstream transport (GHG Protocol Categories 4 and 9). For large steel, aluminium, and cement companies — all of which are in the top 1,000 — this means transport emissions must be measured and disclosed annually. While BRSR does not currently require verified reduction targets for Scope 3, investors, ESG rating agencies, and procurement officers are increasingly comparing companies on their Scope 3 intensity. A company that uses road freight over 1,200 km when rail is available and cheaper carries a higher Scope 3 burden than one that does not — and this difference is now visible in public disclosures.
EU buyer Scope 3 obligations. Large European companies that source steel, aluminium, or fertiliser from India are subject to the EU’s Corporate Sustainability Reporting Directive, which mandates Scope 3 disclosure for companies above certain thresholds. Scope 3 includes purchased goods and services (including the embedded production and transport emissions of what they buy). An EU steel service centre buying HRC from an Indian mill must disclose the embedded carbon of that purchase. As this disclosure becomes routine, EU buyers will prefer Indian suppliers whose logistics profile reduces the buyer’s own Scope 3 burden — a commercial preference that favours suppliers who have already shifted to rail. This pressure is current but diffuse; it will sharpen as CSRD’s Scope 3 requirements are enforced more rigorously from 2026 to 2028.
The long-term CBAM transport risk. CBAM currently covers Scope 1 and Scope 2 embedded emissions at the production facility; transport emissions are explicitly excluded. But CBAM’s design logic — equalising the full carbon cost of imported goods with domestically produced goods — is analytically consistent with eventual inclusion of embedded transport emissions. The EU’s CSRD disclosure requirements already capture supply chain transport emissions for large buyers. If and when the EU extends CBAM to include embedded Scope 3 transport emissions, Indian producers using road freight over DFC-accessible corridors will face an additional CBAM cost that their competitors using rail will not. This risk is not imminent but is structurally present and should influence logistics strategy decisions that have 10 to 15 year implications — particularly plant location decisions and siding investment decisions being made now.
India’s National Rail Plan targets an increase in rail’s freight modal share from approximately 28 to 31% to 40 to 45% by 2030. The World Bank has estimated that raising rail’s share from 25% to 40% by 2047 alone could reduce annual CO₂ emissions by over 200 million tonnes. For industrial sectors — where long-haul bulk movements dominate freight volume — the modal shift opportunity is largest. Steel, cement, and fertiliser together account for a significant share of India’s inter-state freight tonne-km. If these three sectors achieved 80% rail modal share for hauls above 600 km by 2030 (from current estimates of approximately 30 to 40%), the sectoral supply chain CO₂ reduction would be in the range of 30 to 50 million tonnes per year — comparable in scale to the GEI reduction that CCTS Phase 1 is targeting for production emissions. Modal shift is the cheapest and fastest available supply chain decarbonisation option for most Indian industrial companies, and it pays for itself on pure freight cost economics.
Frequently Asked Questions
At what distance does rail become cheaper than road for Indian industrial cargo?
The DPIIT-NCAER September 2025 study established that with 50 km of road first-mile and last-mile movement at each end, multimodal transport (rail for the long-haul leg) becomes cheaper than pure road transport beyond approximately 600 km. If the first/last-mile road legs are longer — 100 km each — the break-even shifts to approximately 1,000 km. Below 600 km, road’s door-to-door convenience, lack of transshipment cost, and shorter transit time typically give it the advantage despite its higher per-tonne-km rate. The rail cost basis is Rs 1.96 per tonne-km for the rail leg; road is Rs 3.78 per tonne-km. For very heavy bulk cargo on long-haul trailers (above 55 tonne axle load), the road line-haul cost can fall to Rs 1.51 per tonne-km — below rail’s Rs 1.96 — but this applies only to the line-haul segment and excludes loading, unloading, documentation, tolls, and transit risk costs.
How does Indian Railways’ electrification affect its freight carbon intensity?
Indian Railways reached 99.4% electrification of its broad-gauge network by early 2026 — the most electrified major national rail system in the world by percentage, ahead of the UK (39%), Russia (52%), and China (82%). Electrification allows rail to source traction energy from the national grid rather than diesel. As India’s grid decarbonises — with the grid emission factor falling year on year as renewable capacity additions accelerate — the rail CO₂ per tonne-km figure of 11.5 g will fall further automatically, without any change to rail operations. A rail network running on electricity generated primarily from renewable sources would eventually approach near-zero traction emissions. Diesel saved by electrification in 2024-25 alone was approximately 178 crore litres — approximately 62% reduction in diesel consumption versus the pre-electrification baseline. Indian Railways targets net-zero by 2030, combining electrification with renewable energy procurement at stations and depots.
Do CCTS or CBAM currently create direct incentives for industrial shippers to use rail?
Not directly. Transport is not currently a CCTS obligated sector; freight emissions are not part of the GEI calculation for steel, aluminium, cement, or fertiliser producers under CCTS. CBAM covers Scope 1 and Scope 2 emissions at the production facility; transport emissions are explicitly excluded from embedded emission calculations. However, two indirect pressures apply. First, BRSR requires listed companies to disclose Scope 3 emissions including transport, creating investor-facing visibility into logistics carbon intensity. Second, EU importers subject to CSRD must account for Scope 3 from their supply chains, which reaches back into the freight decisions of Indian exporters. A third, forward-looking pressure: if CBAM is extended to include embedded transport emissions in future revisions, Indian producers using electrified rail will carry a significantly lower embedded freight carbon cost than those using diesel road transport — a competitive advantage that currently has no direct financial value but could acquire one within the CBAM’s expansion horizon to 2034.
