The E20 mandate did not come from a single ministry. Two distinct arms of the central government — the Ministry of Petroleum & Natural Gas (MoPNG) and the Ministry of Road Transport & Highways (MoRTH) — share responsibility for the policy, each controlling different levers. Understanding who did what, and when, is essential to understanding how E20 became India’s only petrol without adequate consumer protection.
Ministry of Petroleum & Natural Gas (MoPNG)
MoPNG controls India’s fuel supply. It sets blending targets, manages ethanol procurement through oil marketing companies (OMCs), and determines what petrol composition is sold at the pump.
Key MoPNG actions on E20
- 2018: Released the National Policy on Biofuels, setting a target of 20 percent ethanol blending by 2030 (later accelerated).
- 2021: Accelerated the E20 target from 2030 to 2025, shaving five years off the timeline.
- February 17, 2026: Issued the notification mandating that only E20 petrol would be sold at regular pumps from April 1, 2026. This is the notification that eliminated fuel choice for consumers.
- Manages ethanol procurement pricing (₹71.86/L for maize-based ethanol as of 2026).
- Published the FAQ admitting E20 is costlier to produce than pure petrol at current crude prices.
Ministry of Road Transport & Highways (MoRTH)
MoRTH controls vehicle standards. It sets what vehicles must comply with, including emission norms, safety requirements, and fuel-compatibility standards.
Key MoRTH actions on E20
- March 2023: Issued the notification requiring all new vehicles manufactured from April 1, 2023 to be E20-compatible. This set the vehicle-side compliance requirement.
- Coordinates with ARAI (Automotive Research Association of India) for testing and certification of E20-compatible vehicles.
- Has not issued any notification, advisory, or mandate regarding the hundreds of millions of pre-April 2023 vehicles already on the road.
The gap between the two ministries
The core problem with E20’s implementation lies in the mismatch between fuel policy and vehicle policy:
| Question | MoPNG (fuel) | MoRTH (vehicles) |
|---|---|---|
| When did they mandate E20? | Feb 2026 (effective Apr 1, 2026) | Mar 2023 (new vehicles only) |
| Transition period? | ~6 weeks from notification to mandate | ~1 year for new vehicle production |
| Old vehicles addressed? | No — all pumps switched to E20 regardless | No — no retrofit, recall, or advisory issued |
| Consumer choice preserved? | No — E0/E5/E10 withdrawn from pumps | Not their jurisdiction |
| Compensation mechanism? | None | None |
MoPNG changed the fuel. MoRTH changed the vehicle standard for new production. Nobody addressed the existing fleet. The result: hundreds of millions of vehicles running on fuel they were never designed for, with neither ministry taking responsibility for the consequences.
Who leads E20 policy?
The driving political force behind the ethanol blending programme has been Nitin Gadkari, who serves as Minister of Road Transport & Highways. While the fuel mandate technically falls under MoPNG, Gadkari has been the most vocal public advocate for ethanol blending, flex-fuel vehicles, and accelerated blending targets.
This dual role — the MoRTH minister being the primary public champion of a MoPNG policy — has blurred lines of accountability. It has also given rise to conflict-of-interest allegations regarding family connections to the ethanol industry, which Gadkari has denied.
The inter-ministerial coordination failure
In well-implemented fuel transitions (the shift from leaded to unleaded petrol, or from BS-IV to BS-VI emission norms), there is typically a coordinated approach:
- Vehicle standards are set well in advance.
- A transition period allows the fleet to turn over.
- Both old and new fuels coexist during the transition.
- Consumer awareness campaigns explain the change.
The E20 mandate skipped steps 2, 3, and 4. New vehicle standards were set in 2023, but the fuel was switched for everyone in 2026 — just three years later — with no coexistence period, no fleet-transition plan, and minimal consumer communication.
For comparison, India’s BS-VI transition gave automakers over three years of advance notice, and BS-IV fuel remained available alongside BS-VI during the changeover. The E20 transition gave consumers six weeks from notification to mandate, with no alternative fuel retained.
What accountability looks like
The movement’s demands address both ministries:
- MoPNG must restore fuel choice: E0, E5, and E10 should be available alongside E20 at every pump. The ministry that controls what goes into the nozzle must stop forcing a one-size-fits-all mandate.
- MoRTH must address the existing fleet: Issue advisories, mandate OEM retrofit support, and facilitate consumer compensation for vehicles damaged by a fuel they were never built for.
- Both must be transparent: Publish the real cost data, the real mileage data, and the rationale for the accelerated timeline. If the policy serves the national interest, make the case honestly.
Two ministries, two sets of notifications, zero consumer protection. The fuel changed for everyone; the vehicle standards changed for new production only. The gap between these two actions is where hundreds of millions of vehicle owners are stranded. That gap is what the movement is demanding both ministries close.
