Peatlands in the Nordic Baltics and climate change

Peatlands in the Nordic Baltics and climate change

Regional Assessment of emission proportionsBy Lars Dinesen, Danish Nature Agency, Chair NorBalWetUNFCCC COP21 in Paris 2 December 2015

Peatlands and Climate- A Nordic Baltic Perspective

A project funded by the Nordic Council of Ministers and prepared by Greifswald University and Risager C.

Outcome a status report on a country assessment of peatlands area and CO2 emissions from drained peatlands based on GIS analysis - ”a second opinion”

Drainage and use during centuries

- In Nordic Baltic countries 44% of the peatlands are drained- Responsible for c. 25 % of the anthropogenic CO2 emission- c. 6% of global peatland CO2-emissions and 0,2% global CO2.

From drainage and excavation to restoration rewetting

Conclusion:Large CO2 emissions from drained peatlandsLarge scale restoration is now taking placeOriginally for biodiversity conservationMitigation of climate change
