Reducing transportation-related GHG emissions is clearly central to any efforts by individuals and families to protect the climate. The car is our major mode of transportation . It is also the main source of transportation-related GHG emissions. When transportation fuels like gasoline are combusted, carbon dioxide and nitrous oxide emissions come out the tailpipe. There are also many other environmental impacts associated with the production, use and disposal of the car.
Cars impose significant economic costs on society.
GHG emissions from personal vehicles are much higher than from any other mode of transportation . Nonetheless, some forms of transportation are even less climate-friendly. For example, travel by aircraft produces significantly more GHG emissions per passenger-kilometre travelled. We all need to make greater use of more climate-friendly modes of transportation. There are many options available, many of which will also save you money.
