Biofuel does emit around the same carbon output to the atmosphere (compared to storing it). Producing the amount necessary to replace most of petrol requires a ton of crop land, and alternatives means of production are not available quite yet, if ever.

Oops, didn’t catch that part from the parent comment. You’re right, it breaks even in most if not all cases.

A side note : EVs are and will be needed for a long time, but an important reduction of personal vehicle use will be needed as well. Shifting the same usage to EVs will surely not be sufficient.

It is less bad, but still pollutes a lot, especially in countries with high-carbon electricity production.
