The emissions specifically include SOx, NOx, ODSs and VOCs [2] and the regulations came into effect in May 2005. [ 3 ] [ 4 ] Annex VI contains provisions for two sets of emission and fuel quality requirements regarding SOx and PM, or NOx, a global requirement and more stringent controls in special emission control areas (ECA). [ 5 ]
NO x gases are usually produced from the reaction between nitrogen and oxygen during combustion of fuels, such as hydrocarbons, in air; especially at high temperatures, such as in car engines. [1] [2] [3] In areas of high motor vehicle traffic, such as in large cities, the nitrogen oxides emitted can be a significant source of air pollution.
The emission rights in RECLAIM are called RECLAIM Trading Credits (RTC), with one RTC for each tonne of NOx or SOx emissions. During 2005, NOx RTC average prices ranged from a low of $1,200 per ton for the Compliance Year 2004 RTCs, to $9,730 per ton for Compliance Year 2008 NOx RTCs, to $10,193 per ton of NOx RTCs for Compliance Years 2010 ...
The main difference is what is defined and what derived. A tax is a price control, while a cap-and-trade system is a quantity control instrument. [ 54 ] That is, a tax is a unit price for pollution that is set by authorities, and the market determines the quantity emitted; in cap and trade, authorities determine the amount of pollution, and the ...
The SNOX process is a very energy-efficient way to convert the NOx in the flue gas into nitrogen and the SOx into concentrated sulfuric acid of commercial quality without using any absorbents and without producing waste products or waste water.
Air pollutant concentrations, as measured or as calculated by air pollution dispersion modeling, [1] must often be converted or corrected to be expressed as required by the regulations issued by various governmental agencies.

NOx, CO, and VOCs are considered ozone precursors. [ 9 ] [ 6 ] Motor vehicle exhaust, industrial emissions, and chemical solvents are the major anthropogenic sources of these ozone precursors. [ 6 ] Although the ozone precursors often originate in urban areas, winds can carry NOx hundreds of kilometers, causing ozone formation to occur in less ...
