Sustainable Event Guidelines

Strategies to Green your Campus Event

What we buy and how we dispose of it has profound implications for people and ecosystems locally and globally. One key action area in Princeton University’s Sustainability Action Plan is aimed at reducing waste and expanding sustainable purchasing. By following these Sustainable Event Guidelines, you will not only be helping to achieve campus sustainability goals, your choices can benefit the larger community and ecosystem.
