19. In order to prevent and mitigate adverse human rights impacts, business enterprises should integrate the findings from their impact assessments across relevant internal functions and processes, and take appropriate action.

(a) Effective integration requires that:

(i) Responsibility for addressing such impacts is assigned to the appropriate level and function within the business enterprise; 21

(ii) Internal decision-making, budget allocations and oversight processes enable effective responses to such impacts.

(b) Appropriate action will vary according to:

(i) Whether the business enterprise causes or contributes to an adverse impact, or whether it is involved solely because the impact is directly linked to its operations, products or services by a business relationship;

(ii) The extent of its leverage in addressing the adverse impact.

Explain how this principle represents the greatest change in business thinking or behavior for MNE's today?
