Preventive and Efficient Driving – Observation and Fuel Saving
Explanation
**Environmental labels** are a way to classify vehicles according to the **polluting potential** of their emissions. This classification is based on the level of pollution that vehicle exhaust gases can cause to the environment. There are four types of labels: **Zero emissions**, **Eco**, **B**, and **C**. Each one indicates the degree of environmental impact of the vehicle.

The main objective of these labels is to **reduce pollution** and improve air quality in cities. Authorities can use this classification to create **low emission zones**, where only less polluting vehicles are allowed to enter. Additionally, benefits can be granted to vehicles with labels that favor environmental care, such as allowing them to drive in special lanes.

Therefore, environmental labels focus on the **polluting potential** of vehicles, not on their noise pollution or energy savings.
