Union Minister Nitin Gadkari expressed concern over Delhi's severe air pollution, stating he develops infections after just two days in the capital. He acknowledged the transport sector, which he oversees, contributes approximately 40% to the pollution, largely due to fossil fuel dependence. Gadkari advocated for increased use of alternative fuels like ethanol and biofuels, questioning the national expenditure on fossil fuel imports and linking self-reliance in clean energy to true nationalism. Delhi's air quality remains in the 'very poor' to 'severe' category.
