A measure of the condition of ambient air with respect to its effects on public health and the environment. Generally defined in terms of concentrations of six principal pollutants: carbon monoxide, nitrogen dioxide, sulfur dioxide, lead, ozone, and particulate matter.
Characterizes the climate and health benefits of adopting world-class standards for new vehicle efficiency/CO2 and conventional pollutant emissions in all members of the G20 Transport Task Group.
The Secretary of the Environment (SEDEMA) of Mexico City hosted a workshop on eliminating particle emissions from heavy-duty buses and trucks in Mexico City.
Current non-road regulatory programs lag behind comparable programs for on-road diesel engines, and are not stringent enough to compel the use of the best available technologies for the control of PM and NOx emissions.
Emissions from the diesel engines of these two key types of non-road mobile sources are expected to be significant, and will potentially have strong negative impacts on local air quality and health in India.
