More about Atlassian
As a horizontal software vendor, its direct environmental footprint is low, but its supply chain—particularly cloud infrastructure—carries significant embedded emissions.

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.
