Sub-project IV addresses the feasible characteristics needed for the roll-out of DACS technologies from a societal perspective. The large-scale introduction of new technologies such as DACS not only depends on technological aspects alone, but also on societal acceptance, legal framework and its impact on climate and society. This transformational potential is investigated in three work packages: (1) The acceptance analysis considers the acceptance of these technologies (as an object) in some specific stakeholder groups, as well as society at large, with a focus on inhibiting and promoting factors and their addressing. (2) An analysis of the legal framework addresses important institutional factors inhibiting or enabling DAC technologies. (3) The implications of a broad roll-out of DACS is assessed in terms of economic (e.g., employment effects, value added) and environmental effects (e.g., GWP reduction potential).
