The numbers are in for this year's i98FM Camp Quality Convoy and there are more than 1.5 million reasons for the Illawarra to smile.
Now, after the community rattled the can to raise $1,539,907, the price of the event's carbon emissions will be determined for the first time.
Wollongong-based sustainability consultancy business Rana Environmental will carry out a cost-free carbon offset program as its donation to Camp Quality Illawarra.
The program will determine emissions associated with the 791 trucks and more than 1200 motorbikes that navigated the 70-kilometre convoy route from Appin to Albion Park Rail on Sunday.
Offsets will be purchased for the emissions and directed to a Tasmanian forest protection project, so the travel component of Convoy can become carbon neutral.
The process involves buying a carbon credit, which has its own identification number and is attached to a particular project.
Each metric tonne of carbon dioxide equals one credit.
"We thought the best way we can [support the convoy], in our unique sort of way, was to provide them with a carbon offset program," Rana Environmental principal consultant Levi Gibson said.
"We've already had really good feedback - they [i98FM] want to expand it to the whole event next year."
Extending the program would include looking at emissions generated by the event's family fun day - this year more than 10,000 people flocked to the Croome Road Sporting Complex.
Mr Gibson said data from the convoy's travel aspect - including the number of vehicles, their type and total fuel consumption - was being collected.
"We convert that into a carbon emissions figure and from that we then have an idea how many carbon offsets we need to purchase," he said.
The final data is expected to be gathered on Thursday.
The 2014 funds have brought the total money raised since the inaugural event in 2005 to $5,952,921.30.
