How green is Mattermost?

We are users of a Mattermost instance, and for a proposal that we are preparing, the Funder is asking us:

  • Does the Organization have formal policies in place on measuring and reducing energy use?

  • Does the Organization have formal policies in place on measuring and reducing water use?

  • Does the Organization have any third-party certifications related to positive environmental performance (such as LEED certification, etc.)?

I wonder if Mattermost has these kinds of policies? It’s the exclusive responsibility of the webserver where it is hosted or has Mattermost good practices related to programming and impact on the environment?
