Carbon Capture – The Importance Of Urban trees CO2 Absorption
One of the main motivators for this campaign is that the public, the government, charities and environmental groups continually vaunt their tree-planting numbers, yet do not seem to have taken on board the massive difference between the carbon capture of saplings and mature trees.
In the Queen’s Wood Oaks campaign Prof Duckett looked at the green credentials posted on the website of Insurance Giant AXA, where it was proudly presented that their members of staff visited Heartwood Forest to plant over 2,500 trees. He calculated that if we assume these were typical 10-year-old saplings, each with a carbon capture of 0.1 pounds/year, this equals a total of 250 pounds of carbon capture per annum.
If AXA had succeeded in cutting down the 4 oaks in North London’s Queen’s wood, each with a carbon capture of more than 60 pounds per annum this would have equalled a total loss of at least 240 pounds of carbon capture and undone all the good work done in Heartwood forest towards helping the UK meet its climate change commitments.
