Support the Movement for Radical Transparency

Become a supporter of the Charter and showcase your organisation’s commitment to authentic environmental advocacy, upholding the highest standards of communications practice.

Why do we need your support?

In an era demanding genuine environmental progress, greenwashing undermines trust and distracts from true sustainability.

The Anti-Greenwash Charter is our collective commitment to authenticity, transparency, and responsible communications practice.

We invite new supporters to help us encourage organisations to communicate their environmental credentials honestly, fostering accountability and benchmarking industry standards.

Your support will amplify the impact of the Charter, driving a global movement towards credible environmental advocacy. To recognise your commitment, you will be given a global license to use our Official Supporter logo (see below) across your materials.

Stand with us against greenwashing and contribute to a truly sustainable future, where organisations’ environmental claims are both reliable and impactful.
