Calculator

This calculator tool has been developed to calculate the annual greenhouse gas emissions (i.e. the carbon footprint) from the transport of wood alternatives being considered instead of Accoya^® wood. To get the end value the following parameters need to be filled in: density (including moisture content), transport distance, vehicle efficiency and life span of the wood in use. To make a custom-made calculation please fill in the white cells within the calculator.
