Carbon Credits for Auto Component Manufacturers in India: CCTS, CBAM and What Actually Works
India's auto component industry crossed a turnover of Rs 7.6 lakh crore in FY2025-26, growing 12.7 per cent and exporting roughly USD 24 billion of parts, according to ACMA. Almost none of those companies are covered by India's Carbon Credit Trading Scheme. That leads many sustainability and procurement heads to conclude they have no carbon obligation at all. They are wrong. The pressure simply arrives from customers and export markets rather than from a regulator, and it arrives with far less notice.
Your plant is not a CCTS obligated entity, and that changes the strategy
Under the Carbon Credit Trading Scheme, greenhouse gas emission intensity targets have now been notified for nine sectors: aluminium, cement, chlor-alkali, pulp and paper, iron and steel, fertiliser, petroleum refining, petrochemicals and textiles. The first four were notified in October 2025 and the rest in January 2026. Automotive manufacturing and auto components are not on that list.
Three practical consequences follow:
You have no emission intensity target to meet and no certificate surrender obligation, so you are not exposed to the shortfall penalty, which is environmental compensation equal to twice the average traded price of carbon credit certificates in that compliance cycle.
Your steel, aluminium and chemical suppliers are obligated. Their compliance cost will eventually show up in your input prices.
You can still participate voluntarily through the CCTS Offset Mechanism, which allows non-obligated entities to register projects and earn carbon credit certificates under BEE-approved methodologies covering renewable energy, industrial energy efficiency, green hydrogen, compressed biogas, waste and afforestation.
That third point is the one most component makers overlook. A captive solar installation or a genuine efficiency retrofit at a forging plant may be registrable, not merely a cost saving.
Where the pressure actually comes from
Two places, neither of them the Ministry of Power.
The first is OEM Scope 3. For a vehicle manufacturer, purchased goods and services is the dominant category, and analysis by CEEW has found Scope 3 accounts for the large majority of Indian vehicle-manufacturing emissions. Tata Motors has science-based targets that include a 54 per cent cut in Scope 3 intensity and net zero for passenger vehicles by 2040 and commercial vehicles by 2045. Mahindra and Mahindra targets a 30 per cent Scope 3 reduction by 2033 against a 2018 baseline. Those numbers can only be delivered through Tier 1 and Tier 2 suppliers. Expect emissions data requests first, then reduction commitments, then a line in the sourcing scorecard.
The second is Europe. The definitive CBAM regime has applied since 1 January 2026 and already captures downstream steel articles such as screws and bolts. On 17 December 2025 the European Commission proposed extending CBAM to around 180 further steel and aluminium-intensive downstream product codes from 1 January 2028, including engines, machinery components and certain vehicle categories. That proposal has not been adopted and must still clear the ordinary legislative procedure, so treat it as a planning assumption. The India-EU free trade agreement contains no CBAM exemption.
Which credits suit this buyer profile, and which do not
Start with what carbon credits will not do for you.
They do not reduce a CBAM liability. CBAM is settled with CBAM certificates priced against the EU ETS, and only a carbon price actually paid in the country of production can be deducted. A retired voluntary credit does nothing at the EU border.
They also cannot be netted off the Scope 3 inventory you report to an OEM. Under the GHG Protocol an offset is disclosed separately from the gross footprint, so a purchase will not improve the emission factor your customer applies to your parts.
Where credits genuinely earn their place for a component manufacturer:
Closing the residual gap on a carbon-neutral plant or product claim used in a customer bid or tender.
Backing a specific programme, such as one plant or one export product line, where abatement is technically capped in the near term.
Building credibility ahead of a formal target, using a small, high-integrity retirement portfolio while capital projects work through approval.
Favour Indian-registered removals and high-integrity avoidance credits with a clear vintage, an accessible verification report and a documented retirement record.
Credits versus direct abatement: do the arithmetic first
For most component plants, whether machining, forging, casting, plating or moulding, Scope 1 and 2 are dominated by purchased electricity and process heat. Open access renewable power, rooftop solar, waste heat recovery, furnace and oven efficiency, and compressed-air leak management usually abate at a lower cost per tonne than buying credits. Crucially, unlike a credit, they reduce the emission factor your OEM customer actually sees.
A sequence that holds up under audit:
Measure Scope 1, Scope 2 and the material Scope 3 categories, with purchased metals first.
Build a marginal abatement cost curve, one cost per tonne for each internal project.
Execute everything that abates more cheaply than the prevailing credit price.
Use credits for the genuine residual, under a written retirement policy.
Push upstream, because your castings, forgings and fasteners suppliers are where most of your footprint sits.
Where to start
If you supply an OEM with a validated science-based target, or you ship parts into the EU, the first deliverable is a defensible emissions inventory, not a credit purchase. Get the numbers right, cost your own abatement options, and buy credits only for what genuinely remains.
