The Forest Engineering Research Institute of Canada (FERIC) interviewed member companies and contractors to quantify fuel usage rates associated with ground-based harvesting, from planning to free growing. Fuel consumption rates for each harvesting system were converted to a common fuel equivalency, litres of diesel equivalent (L d.e.), megajoules of energy (MJ), and grams (g) of greenhouse gas emissions per cubic metre harvested. Finally, the weighted average volume of fuel required for one cubic metre was determined. The report also includes suggestions to reduce fuel consumption rates and greenhouse gas emissions from ground-based harvesting systems.
