泥炭矿每年每公顷可累积高达2.25吨碳。泥炭地面积约3.97亿公顷.泥炭地可能含有3290 - 5280亿吨碳。然而，将泥炭地改造为农业和林业用地的情况可能正在以每年550 000公顷的速度扩大。产生的CO[sub 2]源加上损失的汇，每年总计426-730公吨CO[sub 2]。矿山和泥炭地的开采将导致数千年来积累的碳储存的迅速释放。参考文献200篇，图19，45片
Peat mines may accumulate up to 2.25 t C per hectare per year. Peatlands cover about 397 m ha. Peatlands may well contain 329-528 billion tonnes of carbon. However alteration of peatlands for agriculture and forestry is probably expanding at an annual rate of 550,000 ha. The CO[sub 2] source resulting, added to the lost sink, totals 426-730 mt CO[sub 2] per year. Exploitation of both mines and peatlands will result in the rapid release of a carbon store which has accumulated over millenia. 200 refs., 19 figs., 45 tabs.
