Encourage recycling
If there is a municipal or voluntary recycling system in your community make sure that your school is making the most of it. Encourage students and staff to always sort out their recycling and let the kids know why you are doing it. If there is a refund on certain items, such as aluminium cans, then you can also encourage student's to collect cans as part of a fundraising activity for the school or an environmental charity organisation.

Switch off the lights and other appliances
Classrooms use a lot of energy in lighting. When you are out of the room make sure the lights are switched off. You can often leave the lights off during the day if there is enough natural light through the windows or you are doing an activity that does require the extra lighting, such as story time. If you have DVD players or computers in the room make sure they are completely turned off when not in use. 

Walk or ride a bike to school
Okay, this might not be possibility for everyone, but if school is close enough and the route is safe enough then encourage students to walk or ride a bike. By walking or biking students are getting some exercise and parent's are saving money by conserving energy as well being a bit easier on the environment and climate. Another possibility may be public transport.

Pack a healthy lunch
In the morning rush it is often easier to throw in a pre-packaged lunch from the grocery store than to make something with fresh products. But the ingredients for a healthy diet can also help the planet, especially if those ingredients are locally grown. Resources are also required for all of the additional packaging for those processed lunches and that packaging, which is typically non-biodegradeable, adds to growing mountains of landfill.
