Data of the publication "Identifying hotspots of greenhouse gas emissions from drained peatlands in the European Union"

The dataset includes land use maps and emission maps (t CO₂e ha⁻¹ yr⁻¹) for the EU+ region, with full methodological details described in Identifying hotspots of greenhouse gas emissions from drained peatlands in the European Union.

This dataset provides spatially maps of peatland land use and greenhouse gas (GHG) emissions across the European Union and associated countries (EU+). It integrates the European Wetland Map (EWM, https://zenodo.org/records/15302184) with multiple land-use datasets and IPCC (2014) emission factors to estimate CO₂, CH₄, and N₂O emissions from drained peatlands. 

Land use was derived from the EU Crop Map 2022 (Ghassemi et al. 2024, JRC; 10 m resolution), complemented with the Witjes et al. (2022) European land use map (30 m resolution) for non-agricultural areas and countries outside the EU, and the EU Crop Map 2018 (d’Andrimont et al. 2021) to capture grassland within crop rotations. Additional reclassification was applied based on known peatland typologies such as blanket bogs and heath moors.

Emission factors followed the IPCC (2014) Wetlands Supplement Tier 1 defaults stratified by land use and climate zone, with drainage depth (grasslands) and nutrient/drainage status (forests) refined using the biomass productivity map of Tóth et al. (2013). The emissions dataset provides minimum, mean, and maximum values, which directly reflect the uncertainty ranges reported in IPCC (2014).

All layers were harmonized and processed at a 10 × 10 m grid resolution.
