Brian Scanlan @bscanlan.bsky.social · 08/08/2025Last year Intercom used 41.069 MTCO2e (metric tonnes of carbon dioxide) in our use of AWS. This is equivalent to the electricity used by 8 average homes in the USA. The vast majority of this was produced in the Sydney region - Australia sure loves burning coal. 010
