There is an increasing interest in using forests as a natural solution for enhancing terrestrial carbon dioxide removal, as part of climate smart forestry strategy to have a significant role in climate mitigation efforts. Harvest deferral is seen as one carbon farming practice to increase carbon sequestration in forests. The aim of this study was to evaluate the role of harvest deferral on carbon forest sink potential of Norwegian forests in the short, medium and long-term. Here, we carried out scenario analysis for the whole Norway during the 21st century to assess the effect on carbon sequestration of delaying harvest in a certain number of forests. The scenarios represented different levels of harvest deferral through Norwegian forests. Delaying harvest would increase CO2 removals in the medium (2050) and long-term (2100), resulting in an additional uptake of approximately 6 and 34 Tg CO2, respectively, when extending rotation for 20 years in those plots with high growth increment in the last 5 years. Scenarios where harvest was delayed for a longer period showed slightly higher CO2 removals by the end of the century. While harvest deferral scenarios showed positive effects in terms of climate change mitigation potential, there are several other aspects that need to be considered, such as trade-offs and synergies with other sustainability goals, leakage, market behaviour and willingness of forest owners to get involved in these carbon farming practices.

Rapporten sammenfatter resultater fra utredningsprosjektet «Jordbruk og karbonhandel – kunnskapsstatus og mulige konsekvenser». Formålet med denne utredningen har vært å belyse hvilke muligheter og begrensninger som ligger i salg av karbonkreditter for norske bønder samt å sammenstille og tilgjengeliggjøre informasjon om det frivillige karbonmarkedet og EUs frivillige rammeverk for sertifisering av karbonfjerning. Utredningen er finansiert av midler til klima- og miljøtiltak (KMP).
