Throughout the roadmapping process, we convened the advisory board to: (i) brainstorm the best approach for the roadmapping exercise, and (ii) review obstacles and priority initiatives for DACCS. For the roadmap, lead actors (i.e., academia, industry, government), critical paths and milestones to short (by 2030), medium (by 2040), and long (by 2050) term, and investment cost ranges are provided for all identified priority initiatives.
