Sustainability is an important part of the everyday life at ZIS. With the ZIS Innovates Sustainability initiative, learning how to respect the environment starts as soon as you enter our community. It is our goal to be green. We achieve this by taking different measures locally and globally.

Our local actions at the Upper School include the placement of electric hand dryers in all washrooms, a commitment to PET recycling, an active aquaponics system in our greenhouse, and the goal of a paperless campus through distribution of student and faculty tablets. On a global level our community is investing in an increasing number of carbon offset programs that promote social welfare in Africa and Asia.

The educational culture at ZIS endeavours to promote a student body that is conscience of the environment and highlights the value of sustainability.
