Electric vehicles and public transportation are both viable solutions for reducing GHG emissions, but each has its strengths and weaknesses that must be accounted for. EVs produce no tailpipe emissions, and their overall emissions can be quite low if powered by renewable or nuclear energy. However, their production, especially of batteries, is energy-intensive, contributing to their life-cycle emissions. These emissions are typically offset within a few years of use due to EVs' high operational efficiency. Advancements in battery technology and recycling are expected to reduce these impacts in the future.

Public transport, by moving many people at once, reduces emissions per passenger-kilometer compared to private vehicles. Electrification of public transport can further lower emissions. Their production also involves significant energy use and emissions, especially for larger vehicles like buses and trains. However, if public transportation is used properly, it will reduce the amount of GHG emissions much more significantly, than just replacing private transportation with EVs. It's also worth noting that electric public transportation may not be a viable solution for regions with low population density, difficult terrain, or harsh climate.

In summary, both EVs and public transport typically have lower life-cycle emissions, when used properly, but the overall effect is highly dependent on many factors.
