How can I get more advice on getting a job in climate change?

Opportunity Green does not provide or support unpaid internship opportunities. We believe that all internships should be paid and equally accessible to all regardless of economic status or any other factors.

As a small charity, we do not have the capacity to support many paid internships.

• If we ever offer internships, we will advertise them on this page, run an open and fair recruitment process and commit to paying the London Living wage.
• We also occasionally consider speculative applications, if they are fully funded.

I have lots of ideas for OG, how can I talk to you about them?

If you are an expert in your field who has identified a gap that needs addressing to help secure a climate-stable future, or you already work in climate change and have burning ideas that aren’t being recognised, let us know!

We are keen to hear from experts – find out more about the types of ideas we are looking for and how to contact us on our call for experts page .
