Environmental-level strategies aim to change the alcohol use environment in the campus, community, or both, and thus can affect the student body as a whole or in large subgroups such as those under age 21. Most of the environmental-level strategies on this site seek to reduce alcohol availability, one of the most effective ways to decrease alcohol use and related problems. A few strategies listed below try to reduce alcohol-related harm directly without restricting availability, and are included because colleges commonly use them. This guide isolated these strategies for assessment, and some may not be effective if used alone. Still, they may be useful parts of a multi-strategy effort.
