Coalition Contributors

Volunteer Community

GCC is structured around a network of volunteers. These registered members contribute their time and professional expertise pro bono to the charity. Through the generosity of volunteers and collaborators GCC has been able to build the foundations for a meaningful sector-specific response to the climate crisis. There are many ways to get involved as a volunteer: Research Groups, Action Teams, Region-Specific Groups, Green Teams


In addition to the GCC Team there are several regular contributors who are paid to provide ongoing services that require expertise such as environmental consultancy, event moderators and editorial contributions etc. GCC aims to pay freelancers fairly at the market value.
