    • A comprehensive approach to climate change: Options and obstacles 

      Fuglestvedt, Jan S.; Skodvin, Tora (CICERO Report;1996:04, Research report, 1996)
      The principle of comprehensiveness constitutes an important element in the climate convention, but guidelines as to how this principle is to be understood and implemented are not provided. In this analysis the meaning of ...

    • A review of country studies on climate change 

      Hanisch, Ted; Fuglestvedt, Jan S.; Isaksen, Ivar S. A.; Selrod, Rolf; Strand, Jon; Torvanger, Asbjørn (CICERO Report;1993:01, Research report, 1993)
      Country studies are important instruments for determining national climate policies and adding to the global knowledge on climate issues. They are, however, also the basis for examining the obligations of the Parties under ...

      With the principle of comprehensiveness embedded in the UN Framework Convention on Climate Change (Art. 3), a multi-gas abatement strategy with emphasis also on non-CO2 greenhouse gases as targets for reduction and control ...

    • Climate change: Scientific background and process 

      Alfsen, Knut H.; Fuglestvedt, Jan S.; Seip, Hans Martin; Skodvin, Tora (CICERO Report;2000:01, Research report, 2000)
      The paper gives a brief description of natural and man-made forces behind climate change and outlines climate variations in the past together with a brief synopsis likely future impacts of anthropogenic emissions of ...

    • Climate regulation of ships 

      Torvanger, Asbjørn; Bogstrand, Bjørg; Skeie, Ragnhild Bieltvedt; Fuglestvedt, Jan S. (CICERO Report;2007:07, Research report, 2007)
      This report gives an overview of five possible regulation schemes for carbon dioxide emissions from international shipping. The strengths and weaknesses of the schemes are compared with regard to nine criteria. The two ...

    • Climatic effects of NOx emissions through changes in tropospheric O3 and CH4: A global 3D model study 

      Fuglestvedt, Jan S.; Berntsen, Terje Koren; Isaksen, Ivar S. A.; Mao, Huiting; Liang, Xin-Zhong; Wang, Wei-Chyung (CICERO Report;1997:03, Research report, 1997)
      As a result of chemical processes in the atmosphere, emissions of NOx can both damp and enhance the greenhouse effect. The two most important effects of NOx in this context are increased concentrations of tropospheric ozone ...

    • Direct and indirect global warming potentials of source gases 

      Fuglestvedt, Jan S.; Isaksen, Ivar S. A.; Wang, Wei-Chyung (CICERO Report;1994:01, Research report, 1994)
      Global Warming Potentials for emissions of CH4, CO and NOx that take into account indirect chemical effects have been estimated for five time horizons. The indirect effects of methane emissions that have been considered ...

    • Effects of anthropogenic emissions on tropospheric ozone and its radiative forcing 

      Berntsen, Terje Koren; Isaksen, Ivar S. A.; Fuglestvedt, Jan S.; Myhre, Gunnar; Larsen, T. Alsvik; Stordal, Frode; Freckleton, R. S.; Shine, Keith P. (CICERO Report;1997:02, Research report, 1997)
      Tropospheric ozone changes since pre-industrial times due to changes in emissions have been calculated by the University of Oslo global 3-D photochemical model. The radiative forcing caused by the increase in ozone has ...

    • Effects of reductions in stratospheric ozone on tropospheric chemistry through changes in photolysis rates 

      Fuglestvedt, Jan S.; Jonson, J. E.; Isaksen, Ivar S. A. (CICERO Report;1993:05, Research report, 1993)
      The observed reductions in stratospheric ozone since the late 1970s are likely to have affected the penetration of UV radiation into the troposphere. We have examined the sensitivity and the response of the tropospheric ...

    • Exploring distribution of commitments: A follow-up to the Berlin Mandate 

      Torvanger, Asbjørn; Berntsen, Terje Koren; Fuglestvedt, Jan S.; Holtsmark, Bjart; Ringius, Lasse; Aaheim, H. Asbjørn (CICERO Report;1996:03, Research report, 1996)
      The study reviews and analyzes some major issues that must be considered when defining principles for distributing commitments to reduce greenhouse gas emissions for countries belonging to the Organization for Economic ...

    • Joint Implementation under the Climate Convention: Phases, options and incentives 

      Torvanger, Asbjørn; Fuglestvedt, Jan S.; Hagem, Cathrine; Ringius, Lasse; Selrod, Rolf; Aaheim, H. Asbjørn (CICERO Report;1994:06, Research report, 1994)
      The aim of this report is to analyze the conditions under which Joint Implementation (JI) can contribute to a costeffective abatement of global greenhouse gas (GHG) emissions. JI refers to policies and measures implemented ...

    • Luftfart og klima - En oppdatert oversikt over status for forskning på klimaeffekter av utslipp fra fly
