IIRC the biggest contributor to the transportation's emission are freight ships that cross the oceans. I wonder how they will be solved..
Maybe going all-electric will help people transform their mindset to no-emissions production (since cars live with people, frieghts ships don't), so it could be that this is an important cultural shift.
Oceanic shipping is a big emitter of pollutants that cause acid rain, mostly because its limits on sulfur in fuel are incredibly lax compared to those for cars/trucks. It's not a big CO2 emitter relative to land transportation.
