About CoSphere

CoSphere is a Community of Small-Planet Heroes (ecologically regenerating economies)

Our Approach

CoSphere unites a diverse community of planetary citizens and equips them (and you!) with the tools to instigate transformative change through:

Discussing the Numbers

Accessible analyses of relevant programs, policies, and projects.

  • Leveraging an understanding of both social change and global systems thinking, our program analyses blogs uncover and highlight how specific programs contribute to transformative change.

"Explainers" on complex topics.

  • The "Explainers" blogs leverage science for broad understanding to ensure everyone has access to the latest sustainability science.

Stories about our trials and journeys – because the work of change is a deeply personal one.

  • Working for change can be lonely, uncertain and frustrating—our story blogs connect us through common challenges along the journey to sustainability.

A platform for sharing initiatives, collaboration, and participation.

  • The forum is a space for CoSphere members to share and collectively learn about efforts towards sustainability.


A coalition of diverse organizations and initiatives with a common goal of initiating deep-reaching social-ecological solutions.

  • This will enable genuine lasting success for organizations through aligning actions and values with transformative change and eliminating the potential for solutions to undermine progress elsewhere.

How can we act?


Private Actions: Behaviors that people take to reduce their environmental impacts (recycling, energy saving, etc.).

Social-Signaling Actions: Behaviors that publicly share and signal pro-environmental values, attitudes, identities, and opinions (sharing on social media, participating in an event like Earth Day, etc.).

System-Changing Actions: Behaviors that people collectively engage in to change laws, policies, corporate actions, institutions, and infrastructure (signing petitions, voting, direct activism, etc.).
