The planet is heating up, and a major contributor to this is the use of technology. Therefore, a degree of effort has gone in to making sure mbop is carbon-negative - it does more good for the environment than bad. This is difficult to quantify, but has been accomplished in two ways.
The only 'environmental overhead' that mbop has are the servers it is hosted on. mbop uses Cloudflare and Hetzner to host its services. Both these companies use 100% renewable energy to run their datacentres.
Additionally, 1% of all mbop's income (that's revenue, not profit) is used to fund permanent carbon removal using stripe's climate scheme.
