泥炭地是表面有泥炭层的土地，含有大量有机碳。在欧洲，此类土地面积约 1,000,000 平方公里，几乎占总表面积的 10%。在许多国家，泥炭地几个世纪以来一直被人为排水，不仅导致大量二氧化碳排放，还导致土壤沉降、养分流失、洪水风险增加和生物多样性丧失。这些问题在很大程度上可以通过停止排水和重新湿润土地来解决。湿泥炭地不释放二氧化碳，可以固碳，有助于改善水质，为稀有和受威胁的生物多样性提供栖息地，并且仍然可以用于生物质生产（“沼泽养殖”）。明智地调整泥炭地的土地利用可以大大有助于实现低排放目标，并为农民、经济、社会和环境带来进一步的利益。
Peatlands are lands with a peat layer at the surface, containing a large proportion of organic carbon. Such lands cover ≈1 000 000 km2 in Europe, which is almost 10% of the total surface area. In many countries, peatlands have been artificially drained over centuries, leading to not only enormous emissions of CO2 but also soil subsidence, mobilization of nutrients, higher flood risks, and loss of biodiversity. These problems can largely be solved by stopping drainage and rewetting the land. Wet peatlands do not release CO2, can potentially sequester carbon, help to improve water quality, provide habitat for rare and threatened biodiversity, and can still be used for production of biomass (“paludiculture”). Wisely adjusted land use on peatlands can substantially contribute to low‐emission goals and further benefits for farmers, the economy, society, and the environment.
