The Kyoto Protocol, which came in force in February 2005, allows countries to resort to «supplementary activities» consisting particularly in carbon sequestration in agricultural soils. Existing papers studying the optimal carbon sequestration recognize the importance of the temporality of...

According to several studies, agricultural carbon sequestration could be a relatively low cost opportunity to mitigate greenhouse gas (GHG) concentration and a promising means that could be institutionalised. However the potential for additional carbon quantities in agricultural soils is...

Do countries interact when they decide whether or not to ratify the Kyoto Protocol? If so, what is the nature of these interactions? To answer these questions, we provide a theoretical analysis based on the notions of strategic substitutability and strategic complementarity. Firstly, we analyze...

Simultaneity between commitment periods (2008-2012) of both International and European Emissions Trading schemes may generate distortions in terms of burden distribution among sectors. There will be two levels of trading (a country and an entity level), which both need to be consistent with one...

The actual main objective of international negotiations on climate change aims at elaborating a coordination regime integrating developing countries. The international coordination system built at the Kyoto Conference relies on a coordination system based on quantity based objectives. This...

This text is based on the English translation of extracts from a report to an advisory economic group to the French Prime Minister (Conseil d'Analyse Economique). This report was presented on July 2002 and published in 2003, (Guesnerie(2003). These extracts have been chosen and reorganised to...

Since 1992, the international community is trying to arrive at a multilateral agreement on the reduction of emissions for greenhouse gases. A collective decision mechanism was adopted in 1997: An agreement is ratified if and only if it is approved by a coalition gathering more than 55 countries....

The paper deals with the diffusion of GHG mitigation technologies in developing countries. We develop a model where an abatement technology is progressively adopted by firms and we use it to compare the Clean Development Mechanism (CDM) with a standard Cap and Trade scheme (C&T). In the presence...

This communication summarizes the main findings of INASUD, an Europeanwide research project on integrated assessment of climate policies. The projectaimed at improving the framing of climate policy analysis through the parallel use of various existing integrated assessment models. It provides a...

What is at stake in the climate negotiations is the provision of a global public good, indeed a "clean" atmosphere.The Kyoto Protocol is only a very minor step toward this objective. Looking further ahead in time, beyond the 2008-2012 period, Annex I Parties' commitments will not be sufficient...
