As the effects of climate change become more devastating, institutions across diverse sectors are seeking to implement environmentally sustainable strategies to maintain a positive public image while still growing their enterprises. Colleges and universities are no exception.

In this guide, you can read about some of the best greenest universities in the U.S. according to the Sustainability Tracking, Assessment & Rating System (STARS). Read on to learn about emerging green initiatives and how students can help their schools be more environmentally friendly.

What Makes a University "Green"?

In general, environmentally friendly universities enact policies and programs that promote a healthy campus lifestyle and reduce dependence on finite natural and human resources.

The STARS system lets schools measure and voluntarily report their performance. Almost 700 colleges and universities currently hold a STARS rating. The STARS system aligns with United Nations sustainable development goals.

Universities earn credits based on six criteria: institutional characteristics, academics, engagement, operations, planning and administration, and innovation and leadership. To achieve the highest platinum rating, a school must earn at least 85 points.

How Can Universities Be More Environmentally Friendly?

Universities with a STARS rating must renew their status every three years, which gives them the chance to demonstrate how they have sustained or enhanced their green initiatives. Each of the aforementioned six categories break down into distinct subcategories.

For example, schools can earn higher points for campus engagement by offering environmental education as a professional development option for staff and faculty. Many universities have taken steps toward offsetting their carbon dioxide emissions through more sustainable campus operations and by supporting carbon savings elsewhere in the world.

The higher education nonprofit Second Nature reports that ten U.S. schools have reached total carbon neutrality, with many more institutions projected to achieve this goal within the next decade.

What Can Students Do to Be More Environmentally Friendly in College?

College students are a major driving force behind green campus initiatives and climate action in general. In addition to changing how you eat and spend money, you can help your school become more environmentally friendly by engaging with your community and joining campus groups.

Student government also provides a powerful forum where you can propose community outreach events and shape institutional policy related to areas like recycling, energy consumption, and ethical food sourcing.

Students may also incorporate environmental activism into their education by pursuing a relevant major or minor. Options include sustainable agriculture, renewable energy, and marine conservation.

What Does Sustainable Living Look Like in College?

By attending an environmentally friendly university, you may benefit from energy-efficient dorms and healthier dining options that accommodate a variety of food restrictions and preferences. You can also enjoy more transportation options, such as campus shuttles, well-maintained bike paths, and ride-share programs.

Because their main objective is education, the greenest universities also focus on developing academic programs that center on sustainability, such as urban planning and environmental science.

Many schools also integrate aspects of environmentalism into seemingly unrelated fields of study. A popular example is the online green MBA, which teaches students to consider social responsibility and sustainable practices when coordinating business operations.
