Switching from regular petrol to E20 (20% ethanol blend) is estimated to reduce carbon monoxide emissions by about XX% in two-wheelers and XX% in four-wheelers, with overall projected reductions in carbon dioxide emissions of up to XX million metric tons per year for India.
However, while this is a significant improvement for tailpipe emissions in the transport sector, it's important to note that coal-fired power plants still emit far more greenhouse gases and pollutants overall than what can be offset by ethanol blending in petrol; India's power sector remains heavily reliant on coal, which is a much larger contributor to national carbon emissions and air pollution.
The environmental benefits of E20 are real but mostly focused on urban air quality and reduced oil imports, rather than being a complete solution to the scale of emissions from dirty coal power generation.
