How do electric vehicles contribute to reducing carbon emissions and what are the key benefits they offer compared to traditional combustion engine vehicles?

What “Discuss” demands

present several distinct facets of the issue and connect them into an argument, giving the competing views real weight rather than one line each.

The characteristic failure: a list of points with no argument running through them.

What a top answer must contain

These are the checkable specifics from the marking standard for this question — the actual case, committee, datum or thinker, not an instruction to “give examples”.

Emission math: zero tailpipe; lifecycle gain depends on grid mix — India ~70% coal power today, so full gain arrives with RE growth (500 GW non-fossil 2030 target)
Benefits: energy security (oil import bill ~$130+ bn), urban air quality (transport share of PM2.5), lower TCO from fewer moving parts, noise
Policy stack: FAME-II, PLI (ACC batteries, auto), PM E-DRIVE (2024), state EV policies, EV30@30 aspiration
Top-band caveats: battery-mineral import dependence (Li, Co), charging-infra density, end-of-life battery recycling rules 2022
