Our environment impacts our health.


We teach individuals and communities how to reduce their risk of illness and injury that arise from elements of the environment that surrounds us - this includes the food we eat, the water we drink and the air we breathe. WHEN uses the influence and knowledge of women to become champions for change. WHEN is a trusted source of credible tools and information for women on today’s relevant and emerging environmental health topics.

Since 1994, WHEN has been educating the general public, media and policy makers that environmental health is a key determinant of public health, and has promoted public action for the prevention of environmental health harms.

We want to see an end to toxic exposure-related diseases, but we cannot make these changes alone. Find out how you can get involved.

Over the last nearly two decades, WHEN has provided solid, well-researched information to inform and inspire. I continue to value the amazing work of WHEN in increasing awareness of the links between women’s health and the environment, and between empowering women and the health of the environment itself.
