Mitigation actions:
(1) prohibition or restriction, which involves a ban or heavy curtailment;
(2) an attempt to change behavioural norms, typically via public education, persuasion, or appeals to emotion;
(3) market-based mechanisms, such as a tax or a subsidy, intended to either substantially increase or decrease the cost of a behaviour;
(4) nudging, which involves the deployment of subtle prompts to encourage but not compel alternative behaviours
