EarthGen Logo

The Green Team is proud to say that The Island School has been an EarthGen Sustaining Platinum Level school since 2018, the first school in the state to achieve this recognition. (EarthGen was formerly known as Washington Green Schools.)

Students, teachers and parents at The Island School have worked together since 2009 to make lasting changes in the areas of waste and recycling, water use, energy use, transportation, healthy school buildings and school grounds.  Their achievements include major reductions in waste, measurable increases in composting and recycling, a “no idle” rule in the parking lot, purchasing Green Power from Puget Sound Energy, serving as a collection site for cell phone and CFL light bulb recycling, and creation of animal habitats on school grounds. In the interest of energy efficiency, students carried out a “power down” campaign that educated students and resulted in lower energy usage. Students ran an environmental poster campaign and created winter bird feeders. Trash audits are conducted frequently.

We look forward with confidence and excitement as we continue in the EarthGen process.  There is always more to learn and do toward an even more environmentally aware and responsible way of life at The Island School.
