Various gasses contribute to climate change, for instance methane is over 80 times more damaging than carbon dioxide by weight. This is why greenhouse gas impacts are usually given in terms of carbon dioxide equivalent (CO2e). We calculate the reduction in emissions represented by our activity based on 3 key differences to our competitors:
All together, this means we estimate that for every tonne of wood we collect and reuse, the equivalent of about half a tonne of CO2 is saved.
Due to the difficulty of getting accurate figures, our estimate doesn’t take into account the impacts of diverting from the recycling stream to the reuse stream (the energy and transport costs of recycling can be significant), the implications of deforestation and illegal timber in the wood supply chain, or the impacts of burning wood for fuel, which releases a lot of CO2 but is often classed as ‘carbon neutral’ because the same amount of CO2 is absorbed from the atmosphere as the wood is grown. It is also not a life-cycle assessment; the wood we reuse will still eventually either burn or decompose at some point in the future. There are still many unknowns and the wider role of wood in the carbon economy merits further research.
