Which of the following non-toxic elements is emitted by a standard vehicle?
Preventive and Efficient Driving – Observation and Fuel Saving
Explanation
Standard vehicles emit **carbon dioxide (CO₂)** as part of the gases that exit through the exhaust pipe. Although CO₂ is not toxic at the usual concentrations in the air, it contributes to climate change and is one of the reasons why reducing vehicle emissions is sought.
- Vehicles produce **toxic gases** that pollute the atmosphere, but carbon dioxide is not considered toxic in the amounts emitted by vehicles. However, it is important to reduce its emission to protect the environment.
- **Catalytic converters** in vehicles help reduce pollution by transforming some of the toxic gases into less harmful ones, but CO₂ remains a byproduct of the combustion of fossil fuels.
- **Environmental labels** classify vehicles according to the amount of pollution they generate. Although CO₂ is not toxic, its emission is an important factor in the classification of vehicles to encourage the use of those that emit fewer polluting gases.
Therefore, carbon dioxide is a gas emitted by a standard vehicle, but it is not classified as toxic in the context of vehicle emissions.
