Klimagassregnskapet for arealbrukssektoren finnes nå på kommunenivå. Dette gir kommunene innsikt i utslipp og opptak fra skog og annen arealbruk. Det nye klimagassregnskapet som ble publisert i oktober kan hjelpe norske kommuner med å prioritere tiltak for å kutte i utslippene av klimagasser knyttet til arealbrukssektoren.

Understanding long-term effects of clear-cutting on current soil carbon (C) fluxes in boreal forests is important in the perspective of global C cycling and future forest management decisions. We studied twelve pairs of forest stands in South-Eastern Norway, each comprised of one previously clear-cut stand and one near-natural stand with similar macroclimate, topography and soil properties. We measured aboveground tree litterfall continuously during two consecutive years and soil respiration fluxes monthly during the snow-free period of one year. Ground vegetation litterfall was estimated from destructive biomass sampling. The previously clear-cut stands had on average 12 % higher annual soil respiration rates, 20 % greater tree litterfall, and tended to have greater total aboveground litterfall (12 %), while the near-natural stands had greater litterfall from ground vegetation (45 %). Litterfall from ground vegetation was strongly linked with below-canopy light transmission, but the contribution of this flux to the total aboveground litterfall was minor. Soil respiration rates were related to microclimate, nitrogen concentration in aboveground tree litter and tree basal area. Though, only basal area could be linked to management type differences in soil respiration, that likely has additional unidentified drivers. We found similar temperature sensitivities of soil respiration in the two management types. We emphasise that age of the dominating trees is an integrated part of the differences between these two types of forest stands. Jointly, our results suggest limited differences in the current net soil C balance of near-natural and previously clear-cut stands.

Boreal forests are important carbon sinks and host a diverse array of species that provide important ecosystem functions.Boreal forests have a long history of intensive forestry, in which even-aged management with clear-cutting has been thedominant harvesting practice for the past 50–80 years. As a second cycle of clear-cutting is emerging, there is an urgentneed to examine the effects of repeated clear-cutting events on biodiversity. Clear-cutting has led to reduced numbers ofold and large trees, decreased volumes of dead wood of varied decay stages and diameters, and altered physical andchemical compositions of soils. The old-growth boreal forest has been fragmented and considerably reduced. Here,we review short- and long-term (≥50 years) effects of clear-cutting on boreal forest biodiversity in four key substrates:living trees, dead wood, ground and soil. We then assess landscape-level changes (habitat fragmentation and edge effects)on this biodiversity. There is evidence for long-term community changes af

Solkraft kan bli en viktig del av energimiksen i det grønne skiftet, og planlagte solkraftverk i skog utgjør en betydelig andel av konsesjonssøknadene til NVE. Derfor er det viktig med god kunnskap om klimagassutslipp fra slike solkraftverk.

I Hurdalsplattformen skriver Regjeringen at de ønsker å: «Etablere en storstilt satsing på norsk bioenergi og avansert biodrivstoff i transportsektoren». De ønsker å utvikle en plan som viser hvordan det kan skje «uten at det svekker naturens opptak og lagring av CO2, samt hvor bruken av knappe bioressurser skal prioriteres for å sikre effektive utslippskutt.». Samtidig viser Grønn bok publisert i oktober 2023 at Norge er helt avhengige av biodrivstoff for å nå klimamålene. Vi ser på mulighetsrommet for en slik satsning basert på norsk råstoff, rammer i norsk og europeisk lov og regelverk for en slik satsning, og basert på dette analyserer vi hvilken rolle norskprodusert biodrivstoff kan spille i oppnåelsen av norske klimamål i 2030 under EUs klimarammeverk.

Intensification of forest management is seen as one important measure to increase carbon sequestration and contribute to balance CO2 emissions and mitigate climate change. Potential measures for forest management intensification include increasing the percentage of the area that is actively reforested after felling, planting at higher densities and with genetically improved material, nitrogen fertilization, and pre-commercial thinning. Here we assessed the mitigation potential of these practices in Norwegian forests from 2018 until the end of the 21st century. As a result, when these management practices were intensified, separately and simultaneously, carbon sequestration over the 80-year simulation period was larger than under current practices. Pre-commercial thinning gave the largest additional 80-year carbon dioxide removal increment and fertilization the smallest. The largest accumulated carbon dioxide removal potential occurred when intensifying all the proposed measures in one scenario and was estimated to be around 329.9 Tg CO2 by the end of the century, corresponding to offset more than six times Norway's total GHG emissions in 2022. If the intensification of these practices is considered separately, our results suggested that pre-commercial thinning and active reforestation after felling, in that order, should be prioritized as climate change mitigation measures, followed by genetic improvement, planting density and fertilization.
