Carbon offsetting is akin to an accounting exercise where the carbon emissions released by one activity are offset – rebalanced – by another activity that sequesters – takes in – carbon dioxide. Typically this might be offsetting the carbon emissions from an air flight by as many planting trees as would absorb that quantity of carbon dioxide. The catch there is one of timing. The air flight produces emissions now but the tree will only absorb the equivalent amount of carbon dioxide over a number – tens of not hundreds – of years and a young sapling may in fact release more carbon dioxide than it absorbs. Another option it to offset the carbon emissions by not felling trees so allowing them to continue to absorb carbon dioxide – but that questions why the trees might have been felled in the first place.
