EC Environmental Stewardship

King County Level Two Green School

Eastside Catholic was named a Level Two King County Green School in August 2018 for improving conservation practices on campus.

The King County Green Schools Initiative helps schools and school districts engage their students and employees in learning about and practicing resource conservation. 

The EC Green Team, spearheaded by Class of 2018 students, prepared for Level Two Certification by reducing the school’s overall waste stream of trash, recycling and compost and directed a “Ban the Bottle” campaign to encourage students to use refillable water bottles. The team also conducted a carpool campaign to reduce the number of cars on campus, which resulted in more carpools than individual drivers. Lastly, an anti-idling campaign was launched to reduce air pollution around campus.


In recognition of superior energy performance, the U.S. Environmental Protection Agency awarded Eastside Catholic School ENERGY STAR certification in 2012. Buildings that earn the EPA's ENERGY STAR rating use 35 percent less energy and generate 35 percent fewer greenhouse gas emissions than similar buildings across the nation.

Eastside Catholic is now listed on the ENERGY STAR registry. You can learn more about ENERGY STAR certification at energystar.gov. Eastside Catholic has an active energy management program and is committed to exploring new ways to improve our facility efficiency.
