Carbon Accounting

How do we calculate the amount of carbon dioxide that we have diverted from the atmosphere?

The methodology is explained in the following paragraphs:

Event Registers

Every Job or event that the group undertakes starts with an Event Register. This lists the date, location and purpose of the event together with the names of every participant and the time at which they started and finished at the event. A copy of this document is available in the section on OH&S and is also available here:

This document is also used to list the fuel consumption expended by or during the event; eg. vehicle use, pump operation etc. This consumption data is used to calculate the kg CO2 emitted by or during the event.​

​Job Data Calculations & Summary Sheet

Any event that involves making biochar or collecting wood to be converted to biochar needs to be recorded with all relevant information listed on a job summary sheet.

This document is used to record the volume of char produced, the CO2 emitted by the job, and the net CO2 removed by the job. The formulae used in the calculations are listed on this sheet. The template of the Job Data Summary Sheet is available here:
