Since today is Earth Day, it seems a good time to mention that all New York City public schools are now members of the Green Schools Alliance, a national organization helping schools to cut their carbon footprints.

Last Saturday, more than 650 students gathered at a conference at the Collegiate School to trade strategies (there will be another one in the fall). City Council member Gale Brewer, who attended, said of the conference “it was huge!”

John Shea, Executive Director of the DOE’s Division of School Facilities, is working on benchmarking energy use -- basically, taking baseline measurements -- at the city's public schools. So far, over 850 schools have been benchmarked. Green Schools Alliance will post information online so communities can see how much energy their school uses, and everyone--students, parents, custodians, administrators--can work on saving energy for their school.

What can you do to help your school go green? Make sure your school is using recycled paper, recycling the paper it uses, turning off lights and computers when they are not needed, and reviewing its energy audit. Encourage teachers and administrators to communicate with parents by email and on school listservs to conserve resources. My kid’s school is looking into switching from Styrofoam lunch trays to corn-fiber-based trays and using biodegradable garbage bags, even though they cost a bit more. Ask your principal. Ask other parents. See if your building's custodian might report to the PTA on the school's energy audit, and what savings can be found in your building. Want more ideas? See the Green Schools Alliance website.

On this Earth Day, and every day, it's good to remember that no matter what our educational struggles may be, we all have to live on the same planet.
