The paper also addresses the possible principles and technical requirements that Parties may wish to consider, as the foundations for further elaboration of the mechanisms. Beyond principles, a number of elements of a more technical nature need to be sorted out to set up new market mechanisms, such as: eligibility for participation by developed countries, as buyers; technical definition of baselines, including guidance on a process to agree to baseline levels, and possible revisions; length of the crediting period and frequency of issuance of credits; new trading units and registries; and national authorities for the new mechanisms. In the case of trading, a compliance reserve and liability rules may be topics for discussion as well.
The third issue explored by this paper is domestic implementation of sectoral market mechanisms by host countries, and how the transition between current and future mechanisms could be managed. Transition issues including the situation of existing CDM projects vis-à-vis broader crediting mechanisms and also sectoral trading must be clarified. Domestic policy implementation in developing countries is of paramount importance to ensure the effectiveness of possible new international market mechanisms. Several illustrations are offered to show how a mix of policies could be used to outperform a baseline to generate credits, and how credit revenues could be used to further support domestic policy implementation. Among the options discussed are subsidies to low-carbon technologies (e.g. feed-in tariffs), mandated performance standards, and an entity level baseline-and-crediting system.
