An environmental prevention model includes strategic use of data, community organizing, policy and media advocacy, and enforcement to bring about long-lasting change. Data are used to identify the problem, develop strategy, plan, and monitor progress. Community organizing ensures that community stakeholders are identified and involved to gain public support and change the norms. Environmental change often requires policy change whether it is mandated as in laws or regulations or voluntary via business or social policies or procedures. Media advocacy is the strategic use of media to gain public and policymaker support for policy or norms change. Finally, enforcement is essential to ensuring that the changes made are sustained over time.
