NEW DELHI: In a significant policy boost to India’s ethanol blending programme, the central government has exempted petrol mixed with 22% to 30% ethanol from central excise duty.
This move, notified on June 10, 2026, aims to make higher-blend biofuels more economically viable, reduce dependence on imported crude oil, and support domestic agriculture and cleaner transportation fuels.
Details of the Exemption
The exemption covers specific blends; E22 (22% ethanol), E25 (25%), E27 (27%), and E30 (30%) where the remainder consists of motor spirit (petrol).
These fuels must conform to standards set by the Bureau of Indian Standards (BIS), which notified technical specifications for these higher blends on May 19, 2026. These standards define the quality benchmarks, safety protocols, and testing methods for blending and composing the fuels.
The tax relief applies to central excise duty and related cesses, provided duties have been paid on the petrol component and applicable GST on the ethanol.
These higher ethanol blends (E22 to E30) that are now exempt from central excise duty are not yet available at retail petrol pumps across the country. While the policy and standards are now in place, oil marketing companies are still in the process of setting up the necessary infrastructure for their rollout.
This incentive follows the successful achievement of the E20 blending target ahead of schedule and the recent launch of E85 fuel (85% ethanol) on June 5, which is priced around ₹20 per litre cheaper than standard E20 to account for its lower energy density.
E85 rollout began recently with an initial ~48 stations, and the government is expanding this network for flex-fuel vehicles.
Plans are underway to expand retail availability of E85 (85% ethanol) fuel, with 50-100 dedicated ethanol fuel stations targeted initially in major cities like Delhi-NCR, Pune, and Mumbai, scaling up to 500 stations by the end of 2026.
Strategic Context and Objectives
India, the world’s third-largest importer and consumer of oil, has long pursued the Ethanol Blended Petrol (EBP) programme to cut its massive oil import bill, lower carbon emissions, and create additional income streams for farmers growing sugarcane, maize, and other feedstocks.
Higher ethanol blends help substitute fossil fuels with domestically produced biofuels, enhancing energy security especially at a time of global oil market volatility.
The policy aligns with broader goals of promoting cleaner fuels and supporting rural economies. By removing the tax burden on these blends, the government seeks to encourage oil marketing companies, distilleries, and auto manufacturers to scale up production, distribution, and vehicle compatibility for fuels beyond the current E20 standard, which remains widely available and compatible with most vehicles on Indian roads.
Background on India’s Ethanol Journey
The EBP programme has seen remarkable progress over the past decade, driven by coordinated efforts between the central government, states, and industry.
Achieving E20 blending has already resulted in substantial foreign exchange savings, reduced CO2 emissions, and support for the agricultural sector. The introduction of higher blends builds on this foundation, with BIS standards enabling a gradual transition.
Experts note that while higher ethanol content offers environmental and economic benefits, it requires compatible vehicles and robust supply chains. The government has consistently maintained that ethanol blends up to E20 cause no adverse effects on vehicles, with ongoing efforts to promote flex-fuel technology for even higher blends.
Economic and Environmental Implications
This duty exemption is expected to make E22-E30 fuels more competitive in the market, potentially lowering retail prices and incentivizing adoption. For consumers, it could translate into cost savings and access to greener fuel options over time.
For the economy, it strengthens efforts to mitigate under-recoveries faced by oil companies amid fluctuating global crude prices and supports job creation in the biofuel value chain.
Environmentally, higher ethanol blends contribute to lower tailpipe emissions, aligning with India’s climate commitments. The policy also signals confidence in the country’s expanding ethanol production capacity, which relies on both first-generation (sugar/molasses) and second-generation (lignocellulosic) technologies.
Industry stakeholders anticipate further measures, such as incentives for compatible vehicles and expanded feedstock options, to sustain momentum.
