Three scenarios (and mixtures between them) are possible. Firstly, (1) NAMAs could receive public funding from developed countries, with emission reductions credited to the implementing country. Alternatively, the system could expand the use of market mechanisms beyond the CDM process. With this option, (2a) NAMAs could receive (partial) public funding from developed countries, and reductions could be (partially) credited to the financing country as offsets; and/or (2b) NAMAs could generate certified offsets which could be sold in the private carbon market. In terms of burden sharing, the two latter mechanisms are a priori equivalent, since the market buyers would be private entities from developed countries that purchase credits to meet their domestic cap requirements. It would of course also be possible for (3) NAMAs to be funded by developing countries, who then retain the credits.
