What are the characteristics of the most 'green' high schools?

I'm trying to understand how a school can be considered 'green'. What environmental or sustainability measures does a school need to implement to be considered one of the most green high schools? Are there any well-known examples?

High schools can be considered 'green' based on several factors including their physical facilities, curricular offerings, and institutional practices. The 'greenness' of a school is often understood in terms of its commitment to sustainable practices, reducing environmental footprint, and educating students about environmental issues.

1. Facilities: A green school might be equipped with energy-efficient technologies such as solar panels or a geothermal heating and cooling system. They may use LED lighting, have a recycling program, and utilize water-conserving fixtures.

2. Curriculum: Green schools often enrich their curriculum with a strong focus on environmental education. They may offer classes on sustainability, environmental science, and climate change. Field experiences and outdoor learning opportunities can also be part of the learning pathway.

3. Practices: Green schools might establish sustainable food programs like offering vegan or locally sourced options. Zero waste initiatives, like composting and recycling everyday items might also be executed. They often promote active transportation (biking, walking, or carpooling) to reduce carbon emissions.

4. Student Engagement: Additionally, student clubs centered on environmental advocacy and sustainability might be prevalent. The existence of these clubs not only supplements the curriculum but also indicates a culture of sustainability embraced by the wider school community.

A well-known example of a 'green' school is The Green School in Bali, Indonesia. Though it's an extreme example (not all schools can have bamboo structures or generate their own solar power like it does), it still serves as a model of what a commitment to sustainability can look like.

Also, Green Ribbon Schools program by the U.S. Department of Education recognizes schools implementing these practices well. Their list of honored schools can provide you a sense of what 'green' high schools look like in the U.S.

Remember, every school's path to becoming 'green' will look different based on their available resources. However, the commitment to sustainable practices and education about environmental issues is a common thread.
