What is the emission standard Euro

The early 90s with the dangerous consequences of global warming and pollution from cars, Europeans are thinking about developing standards based on emissions from light vehicles were heavy. Unchangeable standards that are stricter from year to year.
Maximum allowable emission standards for emissions from new cars in Europe that are sold in Europe Union countries to define. Currently, emissions of nitrogen oxides (NOx), hydrocarbons (THC), non-methane hydrocarbons (NMHC), carbon monoxide (CO) and particulate matter (PM) and it is. For each vehicle type, different standards apply.
The standard engine is an engine test in a given test cycle is checked. Engines that do not meet this standard are not salable in Europe. But the new standards will not be applied to previous cars. There is no obligation to use a specific technology, however, to set the standard, features technologies that are available to be considered. Completely new models introduced must meet the standards, but little change in a technology that is being produced can work with the previous standard.
CO2 emissions
In Europe, 20% of total road transport CO2 produces the share of passenger cars is 12%.
The Kyoto Protocol drop of 8 percent from 1990 to 2012 is set to release the gas.
Contribution to CO2 emissions of road transport is increasing sharply, from 21% in 1990 to 28% in 2004, but no limits on CO2 emissions for cars has not been determined. Today, the share of road transport emissions in Europe relative to the total emissions in the world 3. 5%. It should be given information about any vehicles to customers so that customers can purchase decisions.

Iran's government to protect the environment and prevent pollution, the standard timetable limit emissions of gasoline, diesel and dual fuel domestic and imported and motorcycles can be determined. Accordingly, the standard limit emissions of light vehicles, heavy and semi-heavy in the years 1389 and 1390 will be EUR 2. But during the years 1391, 1392 and 1393 this car should earn Euro 4 standard. [1]
All automakers are required from 29 December 1390 to end 91 years of production standard Euro-2 to Euro 4 upgrade your car. [2] Earlier in 1384, according to a previous decision of the Council of Ministers, for light and heavy vehicles up to 1388 euro 2, from 1389 to 1391 Euro 3 and Euro 4 from 1392 to 1393 was considered. [3]
For this purpose, projects an increase in fuel quality, definition and are running in the second half of 1390 and gradually quality products EU IV (Euro 4) and EU V (Euro 5) to be released. [4] However, the it was at least 8 million liters per day of fuel at the end of June 1390 in accordance with the Euro 5 fuel stations in Tehran to be released. to be distributed with the Euro 4 standard.
