Peatlands and Climate Change – 2008 and 2021

Peatlands interact with climate through the uptake and release of greenhouse gases (GHGs). These are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Emissions and their impact on climate and vice versa are studied worldwide by thousands of scientists, many of whom are members of the IPS.

To understand the GHG balances of peatlands, a profound knowledge of their biology, chemistry and hydrology is required. There are also differences between geographical regions and mire types, which need to be taken into consideration. Mires are important carbon stocks and can act as a sink or a source of GHGs.
