Citing figures on water usage, he said producing one litre of sugarcane-based ethanol requires around 3,630 litres of water, while rice-based ethanol can consume up to 10,790 litres per litre of fuel. Even maize-based ethanol, he added, requires approximately 4,670 litres of water for every litre produced.
Ramesh said these figures were particularly concerning at a time when groundwater levels are declining across several parts of the country and agricultural resources are under increasing pressure.
He also referred to the recommendations of NITI Aayogโs 2021 ethanol roadmap, which, he said, acknowledged the need to gradually move towards more sustainable feedstocks for ethanol production.
However, Ramesh alleged that the government had moved in the opposite direction by encouraging the use of food grains for ethanol production. He pointed to the governmentโs admission in Parliament that rice was being supplied to ethanol distilleries at nearly 40 per cent below its average procurement cost.
“A genuinely green fuel policy must account for the entire ecological footprint of the fuel it promotes,” Ramesh said, arguing that the push for E20 was driven by considerations other than environmental protection.
The Congress had intensified its attack on the E20 rollout a day earlier, alleging that the fuel transition had reduced consumer choice, increased costs for middle-class vehicle owners and raised concerns over vehicle compatibility.
The party claimed that ethanol producers were the primary beneficiaries of the policy and demanded greater transparency, data and public accountability from the government on the impact of E20 fuel.
The government, however, has promoted E20 as a key step towards reducing crude oil imports, cutting emissions and supporting domestic ethanol production. The rollout is part of Indiaโs broader biofuel strategy aimed at increasing the share of ethanol blending in petrol.
