Low Carbon Transportation
The document discusses various low-carbon transportation options for British Columbia and beyond. It examines electric vehicles like cars, buses and trains powered by batteries, overhead wires or hydrogen fuel cells. It also evaluates cargo transportation using trolley trucks, pipelines and more efficient vehicles. Biofuels are mentioned but have limitations. Overall, the document advocates pursuing a variety of technologies like lightweight electric vehicles, improved public transit and rail electrification to transition to low-carbon transportation.
