Even if every internal-combustion-engine vehicle on the road were traded for an electric one, transport would still have a sizeable environmental footprint. While emissions from fossil fuels such as petrol or diesel would reduce, the footprint of the critical mineral in the EV battery could be significant, and the road dust emanating from tyre friction would remain unchanged. It’s clear that to reduce its environmental footprint, the transport sector must switch to cleaner fuels and aggregate demand. The impact of such a move is now available for all to see in Delhi Metro‘s CarbonLite Metro Travel, which quantifies the amount of carbon dioxide emissions saved by each passenger if they choose to take the metro instead of a private vehicle, taxi or ride-share. This emission-saving figure is published on paper and mobile QR tickets. The initiative is in line with GoI’s LiFE programme and will encourage passengers to choose an eco-friendly mode of transport.
However, even the most extensive metro network will find it challenging to serve the vast Indian cities. Population sizes and areas to be covered require an integrated approach to public transport. Ensuring seamless movement between the different segments – metro, bus, train and tram – will make it possible for the increasingly climate-conscious user to do their bit for the planet. Time saved and cleaner air will result in productivity gains and economic benefits. Other gains include public safety, and commercial and entrepreneurial opportunities.
