Why we exist

We see a world in which business is a catalyst for a just transition. To make this possible, every employee needs to feel that their job is a climate job - a job that can support a just transition. We encourage and equip employees with the leadership skills they need to challenge the status quo, actively influence their organisation and initiate positive action around social and environmental issues. We hold space for organisations who want to learn how to embrace the collective intelligence of their workforce to take action on climate change, inclusion and justice. 

The Undercover Activist is creating a learning hub for employee-led change. To embolden professionals to confidently organise and take positive action around climate change and social justice in their workplaces.


Get involved through online courses, meet-ups, written, audio, visual storytelling, speaking and campaigning, and inspire people to mobilise, organise and drive positive change from within.
