NitiAayog Rejects Mahindra, Tata And JSW-MG's Request To Shift Directly From ICE To EVs
Niti Aayog has refused a request from Tata Motors, Mahindra and JSW MG Motor to narrow the definition of zero-emission vehicles so that it applies only to pure electric vehicles, reports HinduBusinessline.
Instead, it has stuck with a broader classification in its February 10, 2026 transport report, where the ZEV basket includes ethanol-based flex-fuel vehicles, compressed biogas vehicles, hybrids, battery electric vehicles and hydrogen-powered vehicles. For the three carmakers that objected, this is not a small wording issue. It goes to the centre of how future clean mobility policy may be framed.
Their objection is easy to understand. Battery EVs and hydrogen fuel-cell vehicles fit the usual tailpipe-emission definition more cleanly than hybrids, flex-fuel cars or CBG vehicles, all of which still rely on combustion in some form.
Mahindra had argued that classifying FFV and CBG-run cars as ZEVs is not technically accurate because combustion inevitably produces tailpipe emissions, and it also noted that such vehicles are not generally recognised as ZEVs in other countries or in existing government policy documents.
Tata and JSW MG were pushing for the same basic clarity from another direction, namely that the industry should move faster toward electrification rather than broaden the label around other technologies.
Niti Aayog’s position is that the transition to cleaner mobility should not be judged only through the narrow lens of tailpipe emissions.
It has backed a wider technology mix in the run-up to the 2070 net-zero target and has said the long-term strategy should support adoption of BEVs, FFVs, CBG vehicles and hydrogen vehicles, with acceleration planned by segment. The think tank has also argued that emissions should be assessed across the full lifecycle rather than through the exhaust pipe alone.
That logic works better on paper than in a showroom. A lifecycle view can be useful for policy planning, especially when fuels, power generation and supply chains are all changing at the same time.
But the moment the term ZEV is stretched to include technologies that still burn fuel, the label becomes harder for buyers, regulators and even automakers to read in a straightforward way. This is where the disagreement becomes practical rather than academic.
For Tata, Mahindra and JSW MG, the concern is not just technical purity. These companies have put real money behind EVs and would naturally prefer a policy vocabulary that clearly separates zero-tailpipe-emission vehicles from lower-emission combustion pathways.
If all of these technologies are grouped together too loosely, the policy signal can get blurred. A manufacturer investing heavily in dedicated EV platforms may feel that the regulatory reward for that bet is being diluted.
On the other side, a broader definition gives more room to companies and sectors that want biofuels, hybrids or gas-based pathways to stay in the transition mix for longer.
Niti Aayog’s report appears to support exactly that phased route, starting with the gradual exit of dirtier diesel use and moving through cleaner alternatives before a fuller rollout of what it calls ZEV technologies. From a policy management angle, that gives the government flexibility. From a market clarity angle, it also creates a mess that will need careful handling.
In my view, the problem is not that multiple technologies are being kept alive. The problem is the use of the ZEV label for vehicles that do not meet the plain-language expectation of zero tailpipe emissions.
Buyers can understand a mixed transition. What they should not have to decode is whether a vehicle that still burns fuel is being treated as zero-emission for policy convenience.
That is why Niti Aayog’s rejection matters. It keeps the broader technology pathway intact, but it also leaves the industry with an unsettled definition that can affect future regulation, incentives and compliance language.
Unless the government separates transition technologies from genuine zero-tailpipe-emission vehicles more clearly, this argument will keep coming back in every major policy discussion that follows.
