However, recalling that this is not at present the main avenue for mitigation under the Paris Agreement, it remains to be seen whether demand for developing country emissions reductions will be a major source of exchange and opportunity or only play a minor role. It is also unclear whether the scope of the SDM will specifically favour LDCs or a broader group of developing or vulnerable states that reflects the specific circumstances of the SIDS - an issue that arose under the CDM of the Kyoto Protocol20. Again, however, the vague nature of the Paris Agreement's provisions on technology transfer commends some caution as to how and when this element of the agreement will actually affect the global economy.
