Transportation is a leading source of carbon emissions globally. The daily commute, often taken for granted, plays a massive role in an individual's overall footprint. Driving alone in a gasoline-powered vehicle is highly inefficient compared to alternatives. Public transportation, such as buses or trains, drastically cuts per-passenger emissions. Carpooling is another effective method right behind walking or cycling, both of which have zero emissions. If driving is unavoidable, maintaining proper tire pressure and avoiding aggressive acceleration can improve fuel efficiency. Switching to an electric or hybrid vehicle is one of the most impactful long-term choices you can make.
