About this question

Why in news

The government defended its E20 ethanol blending programme in the Lok Sabha in August 2026, citing roughly Rs 1.98 lakh crore in forex savings, amid an active opposition campaign alleging vehicle damage and consumer backlash from legacy vehicle owners.

Why for UPSC

Chronology questions test whether an aspirant has internalised the actual sequence behind a policy rollout - here, distinguishing the vehicle-compatibility mandate, the blending-target achievement and the later parliamentary disclosure - rather than just recalling isolated facts about the programme.

Prelims summary

India's E20 rollout unfolded in sequence: the April 2023 BS6 Phase 2 mandate created a vehicle-compatibility cutoff, the 20% blending target (advanced from 2030) was met by 2025-26 and the government's Rs 1.98 lakh crore forex-savings claim was presented to the Lok Sabha only in August 2026, amid opposition criticism.
