This carbon pool is stabilized by the low temperature on temperate peat, and by the water logging on tropical peat.

This soil is problematic because it exhibits poor consolidation properties – it cannot be easily compacted to serve as a stable foundation to support loads, such as roads or buildings. Graphite is only technically considered a coal type. Normal Highland whiskies have a peat level of up to 30 ppm, and the whiskies on Islay usually have up to 50 ppm. This factor is again emphasized because it is frequently
In connection with peat extraction there remain a number of
Removing wood fragments is the main constraint to mechanized
ideal conditions the area needed is less (15 m2). This leads to lower levels of CO2 storage than the original peat bog. Mostly used for power generation and metallurgy. Peat appeared especially competitive in the 60-200 MW
Total CO2 emissions from the worldwide 500,000 km2 of degraded peatland may exceed 2.0 Gtons (including emissions from peat fires) which is almost 6% of all global carbon emissions.[73]. moisture content, ash content and calorific value of peat (source Ekono

In 2018, the Netherlands imported 2,252 million kg of peat (5.63 million m3 (400 kg/m3 dry peat[43]): 54.2% from Germany, 9.5% from Estonia, 7.8% from Latvia, 7.2% from Ireland, 7.1% from Sweden, 6.6% from Lithuania and 4.9% from Belgium); 1,185 million kg was exported.
