A calculator for local peatland volume and carbon stock to support area planners and decision makers

Abstract

Conserving soil carbon is one of many actions to take in limiting global warming. However, carbon dense peatlands are still being drained or excavated. Infrastructure development is one of the major current threats to boral peatlands in Fennoscandia, but few tools are available for calculations of carbon stocks in peatland areas, necessary for decision makers planning development projects. Thus, we compiled a reference database of key peat characteristics from main boreal peatland types sampled in Norway and tested “best practice” peat depth sampling methods and peat volume interpolations. We implemented our findings in CarbonViewer, a tool and easy-to-use app that reliably calculates carbon stocks of delimited peatlands. Tool and method presented, estimates carbon stocks to assess potential soil carbon loss in planned infrastructure development on peatlands and will give decision makers the necessary knowledge base to limit emissions from soil carbon.
