The government's E20 petrol rollout, despite extensive consultations and successful trials, lacked clear communication to vehicle buyers. This fueled misinformation and public doubt about engine health, despite no apparent damage. Policymakers failed to adequately share deliberations and trial results. Continuous, transparent communication is crucial to build public trust, ensuring India's energy security and climate goals. In the world's third-largest automobile market, communication gaps are costly. Proactive messaging and widened stakeholder engagement are essential to dispel misinformation and ensure the blending initiative's success.
