Calculate the carbon footprint of ONE average car journey!

In 1976, there were 342 million cars on our roads across the world. By 1996, there were 670 million and in 2016, there were almost 1.4 billion. If we are to assume that this level of growth continues, we will have 2.8 billion cars on the roads by 2036.The car is seen as a symbol of our individual mobility and independence.

We need to understand that as well as local pollution (smog and poor air quality), our excessive car use is having a severe effect on our environment. The exhaust from a car releases hydrocarbons and nitrogen oxides, which together react with sunlight to increase ground-level ozone. Car exhaust also releases carbon monoxide, which threatens human health, and carbon dioxide, which contributes significantly to global warming.

For this reason, wherever we can, we must try to travel by individual cars as little as possible, or drive energy-efficient vehicles. There are also green initiatives that can offset the unavoidable CO2 emissions in special climate protection projects.

We have determined the volume of CO2 emissions arising from an average Irish car journey using third-party research calculators. This journey is based on a round-trip from Greystones to Dublin city.

Calculation principles

The car calculator determines the CO2 emissions that happen during a car journey. This takes into account the Direct Emissions arising from fuel combustion but also so-called Grey Emissions. The latter arises from the production of the vehicle, the provision of road infrastructure and the extraction, transportation and processing of the crude oil.

The maximum amount of CO2 a person should produce per year in order to halt climate change 0.600 t CO2

The amount of CO2 an EU citizen produces each year on average 8.4 t CO2
