I can't see you, Tony, so apologies for interfering there.
Fifty per cent of the weight of wood is carbon, so basically it's any plant, any woody plant that grows fast and has a high density in its wood. An oak will have a higher density than a poplar, but it grows more slowly. At the end of the day, it comes down to how much carbon you can accumulate in the wood, in your forests, in your urban forests, in your parklands, and in your shelter belts. We have plenty of opportunities across the country to grow more trees and to remove more carbon dioxide from the atmosphere in the process.
