IssuesVariability and Change
Tasmania does not have sufficiently large urban centres for emissions to air from transport to be a major environmental concern, although such emissions are an important consideration in the total exposure of the population to air pollution. These transport-related emissions include carbon dioxide (CO2) from the combustion of fuel, methane (CH4) due to incomplete fuel combustion, and nitrous oxide (N2O), which has increased due to the use of three-way catalytic converters. Other emissions include carbon monoxide (CO), sulphur oxides (SOx), and non-methane volatile organic compounds (NMVOCs).
Several air pollutants are also associated with adverse health effects (see also Air Toxics Issue Report). Some volatile organic compounds are known carcinogens, notably benzene, while carbon monoxide, nitrogen oxides and sulphur oxides are also serious air pollutants. Some transport air emissions also contain lead (Pb) and fine particulate material (PM10), both of which are associated with adverse health effects.
This 'At a glance' section provides an overview of transport emissions to air. More detailed information and references are available in the Transport Emissions Issue Report. An indicator on the Emission of Air Pollutants is included within the report.
