The Fundamentals

The Institution of Environmental Sciences (IES) is a charitable organisation and a global professional membership body for environmental scientists. We work to unite people and specialists from diverse disciplines around the shared goal of accelerating the transition to a sustainable society.

​

We support a diverse and interdisciplinary network of environmental scientists all over the world – and at every stage of their education and careers – to connect, develop, progress and inspire.

​

Our strong ties with academia, government and the professions mean we’re in a unique position to influence evidence-based, transformative change.

​

Through our network, the IES helps professionals connect and work together to solve the world’s most pressing environmental challenges.
