Example Of The Distance Remaining: Cornwall's Trees Absorb 7% Of The Carbon Cornwall Emits Annually
Environmental campaigners warn that years of deforestation has left areas of the UK lacking in "one of its biggest natural allies" in the fight against climate change. Trees absorb carbon dioxide (CO2) – the main greenhouse gas – from the air and convert it into wood and oxygen in a process known as carbon sequestration.
Data from the Department for Business, Energy and Industrial Strategy reveals that woodland in Cornwall sequestrated 0.6 tonnes of CO2 per hectare in 2017 – the latest available figures. It means trees in the area captured an estimated 203,600 tonnes of carbon, according to that year’s land size figures from the Office for National Statistics.
Different data from the BEIS department shows Cornwall emitted 2.8 million tonnes of CO2 in the same year, meaning trees would have absorbed seven per cent of the carbon released into the air in 2017.
The ONS measures the amount of money saved by carbon sequestration based on how much would have to be spent to meet emissions targets if the CO2 had to be removed from the atmosphere by other means. In Cornwall, this socio-economic benefit was estimated to be £38 per hectare. South Ayrshire, in Scotland, benefited the most from carbon capture in the UK in 2017, with a value of £171 per hectare. In stark contrast, Boston, in Lincolnshire, east Midlands, received the lowest socio-economic benefit at just 20p per hectare.
