      Lund, Marianne Tronstad; Berntsen, Terje Koren; Fuglestvedt, Jan S. (Peer reviewed; Journal article, 2014)
      Biofuels are proposed to play an important role in several mitigation strategies to meet future CO2 emission targets for the transport sector but remain controversial due to significant uncertainties in net impacts on ...
    • CO2 emissions from biomass combustion for bioenergy: atmospheric decay and contribution to global warming 

      Cherubini, Francesco; Peters, Glen Philip; Berntsen, Terje Koren; Strømman, Anders Hammer; Hertwich, Edgar G. (Journal article; Peer reviewed, 2011)
      Carbon dioxide (CO2) emissions from biomass combustion are traditionally assumed climate neutral if the bioenergy system is carbon (C) flux neutral, i.e. the CO2 released from biofuel combustion approximately equals the ...
    • Elemental carbon measurements in European Arctic snow packs 

      Forsström, S.; Isaksson, Elisabeth; Skeie, Ragnhild Bieltvedt; Ström, Johan; Pedersen, CA; Hudson, S.R.; Berntsen, Terje Koren; Lihavainen, H.; Godtliebsen, Fred; Gerland, Sebastian (Journal article; Peer reviewed, 2013)
      [1] Black carbon (BC) and other light-absorbing particles deposited on snow and ice are known to perturb the surface radiative balance. There are few published observations of the concentration of these particles in the ...

(Peer reviewed; Journal article, 2013)
      We report on the AeroCom Phase II direct aerosol effect (DAE) experiment where 16 detailed global aerosol models have been used to simulate the changes in the aerosol distribution over the industrial era. All 16 models ...
    • Regional temperature change potentials for short-lived climate forcers based on radiative forcing from multiple models 

      Aamaas, Borgar; Berntsen, Terje Koren; Fuglestvedt, Jan S.; Shine, Keith P; Collins, William J (Journal article; Peer reviewed, 2017)
      We calculate the absolute regional temperature change potential (ARTP) of various short-lived climate forcers (SLCFs) based on detailed radiative forcing (RF) calculations from four different models. The temperature response ...
