20.500.12556/RUL-156397 Carbon carrying capacity in primary forests shows potential for mitigation achieving the European Green Deal 2030 target Carbon accounting in the land sector requires a reference level from which to calculate past losses of carbon and potential for gains using a stock-based target. Carbon carrying capacity represented by the carbon stock in primary forests is an ecologically-based reference level that allows estimation of the mitigation potential derived from protecting and restoring forests to increase their carbon stocks. Here we measured and collated tree inventory data at primary forest sites including from research studies, literature and forest inventories (7982 sites, 288,262 trees, 27 countries) across boreal, temperate, and subtropical Global Ecological Zones within Europe. We calculated total biomass carbon stock per hectare (above- and below-ground, dead biomass) and found it was 1.6 times larger on average than modelled global maps for primary forests and 2.3 times for all forests. Large trees (diameter greater than 60 cm) accounted for 50% of biomass and are important carbon reservoirs. Carbon stock foregone by harvesting of 12–52% demonstrated the mitigation potential. Estimated carbon gain by protecting, restoring and ongoing growth of existing forests equated to 309 megatons carbon dioxide equivalents per year, additional to, and higher than, the current forest sink, and comparable to the Green Deal 2030 target for carbon dioxide removals. carbon cycle climate-change ecology climate-change mitigation forest ecology kroženje ogljika ekologija podnebnih sprememb ublažitev podnebnih sprememb gozdna ekologija true false true Angleški jezik Slovenski jezik Članek v reviji 2024-05-23 13:54:03 2024-05-23 13:54:09 2024-05-24 03:56:52 0000-00-00 00:00:00 2024 0 0 Str. 1-13 article no. 256 Vol. 5 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-05-14 63*1:630*2 2662-4435 10.1038/s43247-024-01416-5 196453123 https://doi.org/10.1038/s43247-024-01416-5 1 2c676a00-18fb-11ef-850a-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=183838 Keith_et_al.pdf Keith_et_al.pdf 1 0B83BD7A88201FEEADA1290B9B4CB8E1 635ed3f91b9f4791562980951faede49b8e05b8e03358df70cbd149302e2af05 b7ecc84b-18fc-11ef-850a-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=183841 Biotehniška fakulteta 0 0 0
