Do you really know what “CO2 emissions” actually means? We explain!
Today is World Environment day so we decided to do an interview with tech wizz, Nicol Louw from CAR magazine, about CO2 emissions. You’ve heard the term, right? But do you really know what it is exactly and how badly it affects the environment? Nicol tell us everything we need to know!
What are CO2 emissions?
CO2 is a gas that is a by-product of the combustion process of fuel (diesel or petrol) and leaves an engine through the exhaust system. Other combustion by-products (emissions) are NOx, CO, Hydrocarbons and particulate matter to name a few.
How does it affect the environment?
CO2 is termed a green-house gas and many environmental studies have shown that it is contributing to global warming. This is a controversial subject with many people opposing the theory. It is widely accepted though that curbing emissions in general is a good idea and helps to protect our environment.
How do car manufacturers attempt to lower CO2 emissions from the car?
CO2 emissions are directly linked to fuel consumption – the less fuel that is burned the fewer CO2 emissions are produced. Therefore manufacturers are lowering the fuel consumption of new vehicles by developing more efficient power-trains (example downsizing, direct injection and turbocharging). Lowering the weight of new vehicles will also result in fuel saving and in turn CO2 emissions.
Do you think with lower C02 emissions, it actually is a more green way of living, or would you say it still harms the environment in a big way- even if everybody drives cars that expel less C02?
In my opinion fewer emissions is always a good idea. The exact impact on our environment is still being researched at the moment.
Are there any laws surrounding CO2 emissions in SA?
There’s only a tax that is linked to the CO2 figure of a new vehicle when purchased.
Do you think the general public and/or government is doing too little to reduce CO2 emissions? And should we be very concerned?
The government should focus more on public transport to reduce the CO2 emissions per person. It would also help to give incentives to the public for buying fuel efficient vehicles apart from the lower CO2 tax. The move to electric vehicles in cities can be promoted by providing charging infrastructure.
There you have it! Make sure you keep this in mind next time you buy a car.
