päästömääräykset

Päästömääräykset, or emission standards, are regulations set by governments to limit the amount of pollutants emitted by vehicles and other machines. These standards vary by country and are often adjusted over time to accommodate new technologies and environmental concerns.

In the European Union, päästömääräykset are governed by the Euro emission standard, which sets a specific limit on the maximum amount of pollutants that can be emitted by a vehicle. The current standard, Euro 6, was introduced in 2014 and sets a limit of 0.1 g/km of nitrogen oxides and 6.0 g/km of particulate matter.

Other countries, such as the United States, have their own emission standards, including the Corporate Average Fuel Economy (CAFE) standards and the Tier 3 emission standards. In Japan, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) sets emission standards for vehicles.

The purpose of päästömääräykset is to reduce the negative impact of vehicles on the environment and public health. By limiting the amount of pollutants emitted, these standards can help to decrease air pollution, improve air quality, and contribute to a cleaner and healthier environment.

Manufacturers of vehicles and machines must comply with these standards by installing emission-reducing technologies, such as catalytic converters and particulate filters. Consumers can also play a role by choosing vehicles that meet or exceed the päästömääräykset, which can help to reduce emissions and promote a more sustainable future.
