Why is it important to reduce car emissions?

Reducing the amount of CO2 and other greenhouse gases entering the atmosphere is critical if we are to address climate change and the environmental havoc it is causing. Reduced car use, increased car efficiency and carbon neutralising, via offsetting your emissions, can lead to both a carbon and cost-neutral solution.

What is the purpose of the exhaust emission control system?

Your vehicle’s exhaust system is designed to take care of toxic emissions your car produces. It will 1) direct harmful hydrocarbons away from the driver and passengers, and 2) reduce the air polution your car releases into the environment, helping keep the air clean.

Vehicle emissions contribute to the formation of ground level ozone (smog), which can trigger health problems such as aggravated asthma, reduced lung capacity, and increased susceptibility to respiratory illnesses, including pneumonia and bronchitis.

Why is car pollution an issue?

That’s the gas that comes out of the exhaust pipe when a vehicle burns the fuel it needs to make it go. Carbon dioxide has no colour or smell but it can cause problems for our environment.
