for options feasibility for both mitigation  and adaptation . This assessment allows the range of available options to be considered in a more critical light, particularly when considering opportunities for implementation over the near term. Meanwhile, the other challenge is that of option efficacy. Significant uncertainties remain regarding how well a given option will perform in a specific context and whether it is capable of adequately addressing risk . Such uncertainties can undermine the pursuit of CRD or at least efforts to accelerate system transitions that support CRD  . Accordingly, closer examination of option implementation in the real world, including within different sectoral and regional contexts, would enhance the knowledge available to decision makers regarding which options will best fit the needs of a given CRD pathway.
