Those who have difficulties in adjusting, or where the costs of making adjustments are high, will have to pay more. A uniform regulation, requiring the same performance level of all companies in an industry, could entail higher overall compliance costs and would cause stronger resistance. Involving the groups targeted by a proposed policy (such as companies, consumer groups, or farmers) in the drafting process can help build awareness, understanding and support. Consultation processes can also inform the policy design process on the circumstances of targeted groups and on obstacles to compliance.
