Encouraging worldwide awareness and action to protect our environment

The Environment Committee aims to inform, inspire, and engage the Western Australian community to drive progress towards achieving the United Nations Sustainable Development Goals (SDGs) related to the environment.

To achieve this objective, the Environment Committee strategically designs, develops, and delivers a diverse range of events and initiatives each year targeting public, private, academic, and civil societies.

These events and initiatives are developed around a core strategic theme, which considers the current and potential future environmental, social, and political landscape in Western Australia to ensure the activities of the Environment Committee remain relevant, relatable, and impactful.
