Atlassian's absolute emissions rose 129% since FY2019, driven by Scope 3 cloud and travel growth. Renewable certificates cover office electricity but mask rising operational footprint. Only 8.8% of suppliers have climate targets against a 69% goal, and the company's net-zero claim depends on a data-centre partner with no science-aligned commitment.
Atlassian scores 55/100 (Making progress) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified October 2026.
That places Atlassian joint 50th of 847 companies scored, and joint 11th of 76 in SaaS / Digital Services.
