It is, however, already notably different from CDM in a few important respects. First, whereas CDM emphasized trade in emission credits from project-based activities, the reference to 'outcomes' in 'ITMO' suggests that the SDM will have encompass a broader range of activities. Second, Article 6 expressly provides that the SDM will be used to ’promote sustainable development' alongside mitigation, suggesting a balancing of objectives between exchange in least-cost emissions reductions wherever they may be, and ensuring participation by and benefits to poorer and more vulnerable countries that may otherwise have weaker capacity to participate in the scheme.
