Direct and indirect global warming potentials of source gases

Jan S. Fuglestvedt, Ivar S. A. Isaksen, Wei-Chyung Wang (Report;1994:01)

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 are the ability of methane to increase its own lifetime (through the CH4/OH-feed...

From confrontation to cooperation. A developed country perspective on the role of developing countries' contribution to technology development and transfer

Knut H. Alfsen, Linda Innbjør, Haakon Vennemo (Report;2009:07)

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

Jan S. Fuglestvedt, J. E. Jonson, Ivar S. A. Isaksen (Report;1993:05)

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 chemistry to such changes in UV radiation. Based on observations of ozone column...

What might be minimum requirements for making the mechanism of Joint Implementation under the Climate Convention credible and operational

Rolf Selrod, Asbjørn Torvanger (Report;1994:04)

Joint implementation (JI) is a mechanism under the UN Framework Convention on Climate Change (FCCC). The criteria of the mechanism are yet to be decided upon, but discussions in the International Negotiating Committee (INC) and in other fora have shown large differences of opinions on how to make th...

The state of the ozone layer: A 1994 science update

Ivar S. A. Isaksen (Report;1994:03)

Both the ground based and satellite observation data bases have been extended since the previous international ozone assessment. There are several satellite systems in operation that provide total ozone data, which have been extensively compared with ground based data. One problem with the satellite...

Energy efficiency: A possible no-regrets option for curbing greenhouse gas emissions

Marit Pettersen (Report;1994:02)

The risk of global warming is a problem that is inherently international in its character. A solution may require international cooperation on a wide scale, but binding treaties are difficult to negotiate. Moreover, free rider incentives reduce the chances of successful implementation of these accor...

World Bank appraisal mission to Mexico The GEF - ILUMEX Project

Rolf Selrod, John Magne Skjelvik (Report;1994:08)

These two reports (R1994-07 & R1994-08) were written for the Norwegian Ministry of Foreign Affairs as part of our participation in the World Bank Appraisal Missions to initiate two practical demonstration projects for possible future Joint Implementation projects. The papers give a background and de...

World Bank appraisal mission to Poland May 31 to June 11, 1993. The GEF Coal-to-Gas Conversion Project

Rolf Selrod, Erik Sørensen (Report;1994:07)

These two reports (R1994-07 & R1994-08) were written for the Norwegian Ministry of Foreign Affairs as part of our participation in the World Bank Appraisal Missions to initiate two practical demonstration projects for possible future Joint Implementation projects. The papers give a background and de...

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

Asbjørn Torvanger, Jan S. Fuglestvedt, Cathrine Hagem, Lasse Ringius, Rolf Selrod, Hans Asbjørn Aaheim (Report;1994:06)

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 jointly by Parties to reduce net GHG emissions contributing to meeting their...

Responses in tropospheric chemistry to changes in UV fluxes, temperatures and water vapour densities

Jan S. Fuglestvedt, J. E. Jonson, Wei-Chyung Wang, Ivar S. A. Isaksen (Report;1994:05)

A two-dimensional chemistry/transport model of the global troposphere is used to study the chemical response to i) increased UV-radiation from stratospheric ozone depletion and ii) increased temperatures and water vapour densities that follow from in-creased levels of greenhouse gases. Increased UV...
