NACEluokituksia

NACEluokituksia is a Finnish vehicle rating system used to classify vehicles based on their exhaust emissions. The system was introduced in 1972 and is based on the New European Driving Cycle (NEDC) test, which measures exhaust emissions under standard driving conditions.

The NACEluokituksia rating system assigns a letter grade to vehicles, ranging from E (the lowest emission level) to 1 (the highest emission level). The grades are based on the vehicle's maximum emissions of carbon monoxide, hydrocarbons, and nitrogen oxides.

The meanings of the letters in the NACEluokituksia system are as follows: E (0-1.4 g/km), which indicates that the vehicle's emissions are significantly below the European Union's maximum emissions standards. D (1.4-3.6 g/km) indicates that the vehicle's emissions are relatively low. C (3.6-6.7 g/km), which indicates that the vehicle's emissions are within the European Union's maximum emissions standards. B (6.8-12 g/km), which indicates that the vehicle's emissions are relatively high. A (12 g/km and above) indicates that the vehicle's emissions are significantly high.

In 2000, the European Union introduced the Euro 3 emissions standard, which tightened the emissions limits for vehicles. In 2005, the Euro 4 standard was introduced, which further reduced the emissions limits. Since then, the NACEluokituksia system has been replaced by the Euro standards, and vehicles are rated using the Euro emissions standards instead of the NACEluokituksia system.
