The individual emissions of specific passenger vehicles are influenced by a great variety of factors like the its brand and model, age, mileage, roads, driving style, maintenance and many more.
As a consequence, all conventional calculators are thus operating with nation-wide averages and are very unreliable when it comes to producing precise results. As an example, in the USA it is assumed that vehicles drive an average of 12,000 miles per year and that in doing so, Passenger Cars emit 4.78 tCO2e and Light Trucks, 6.00 tCO2e. This may serve as an interesting reference – but not much more then that.
This is also because the calculation for a car operating in Fiji is further complicated by the fact that Fiji differs substantially from first world countries in that e.g. cars tend to be older and therefore, more polluting and less fuel efficient, that they are less well serviced, that average distances are shorter, that many cars consume additional fuel by operating air conditioners and being kept running on idle, etc.
We therefore strongly recommend NOT to calculate the emissions of your vehicle based on its mileage, but to base that calculation on its real yearly fuel consumption.
After all, you want to offset what you emit and not the theoretical emissions of a theoretical average vehicle in a far away country!
Conversely, we recommend that you familiarize yourself with these and especially these simple and useful tips for reducing your fuel consumption and thus, your emissions.
