The Timber Transport CO2 Calculator
This calculator has been developed to calculate the annual greenhouse gas emissions (i.e. the carbon footprint) from the transportation of wood alternatives being used instead of Accoya®.
To reach the end value the following parameters need to be calculated: density (including moisture content), transport distance, vehicle efficiency and the life span of the wood (the longer the lifespan of the wood, the less replacements required, resulting in less transport). To make a custom-made calculation please complete the cells in the calculator below. For a realistic example (Accoya® wood vs Western Red Cedar from USA) please refer here. This is also prefilled under “wood alternative”.
Please see various prefilled examples at the bottom of this page. All distance calculations have been made using www.sea-distances.org and Google maps. The wood specific weight figures have been derived from www.houtinfo.nl.

Results
This calculator tool has been developed to calculate the annual greenhouse gas emissions (i.e. the carbon footprint) from the transport of wood.
This calculator uses a 50 year life span as Accoya® wood is guaranteed for 50 years. The calculator shows that because of the extended life span and low CO2 emissions per ton.km of sea freight, in various scenarios the annual CO2 emissions (CO2 emissions divided by lifespan) for transport of the Radiata Pine used to produce Accoya® is lower than for alternative realistic wood scenarios (see various examples below).
