Open Letter

To Astronomy Departments, Institutions and Societies:
Adopt Sustanability as a Primary Goal.

We, astronomers, astrophysicists,
and global citizens…

  1. Recognize the urgency of the climate crisis and our impact on it.
  2. We also recognize that we have the power to change our current practices.
  3. We call on astronomical institutions worldwide to set an example for the field in mitigating our contribution to the climate crisis by:
  • Naming sustainability as a primary goal.
  • Putting in place specific sustainable practices to lower carbon emissions.
  • Clearly communicating these changes both to their own members and the general public.

Translations available in English, Dutch, Italian, German, Portuguese, Spanish, and Turkish.
