Transportation
The increasing use of transportation methods and vehicle dependency are major concerns
for social and environmental health. Vehicles are putting damaging CO2 and other
emissions into the atmosphere. Industrialized countries account for 57% of global CO2
emissions, 32% from North America. Twenty-five percent of the total commercial energy
consumed is for transport, approximately half of the total oil produced worldwide. Between
now and 2020 energy demand for transport is forecast to grow by 1.5% per year in
industrialized countries and by 3.6% per year in developing countries, raising significant
questions of sustainability. Consumption patterns in this sector are widely acknowledged
to be damaging to environmental and human health. Air transport is also expected to
increase significantly; it is believed that aircraft greenhouse gas emissions contribute
substantially to climate change mechanisms. Transportation poses additional threats to
human and environmental health such as noise, land use problems, accidents and congestion.
