Centene's reported emissions fell from 2.87 Mt in 2019 to 1.17 Mt in 2025, largely because it cut office space by about 80% after moving to hybrid working, and its Scope 3 is estimated from spending rather than supplier data. It has set no climate targets and discloses no renewable electricity purchasing. It publishes no financed emissions for its investment portfolio, and As You Sow reports that its 401(k) plan channels nearly $200 million into oil, coal-fired utilities and agribusinesses linked to deforestation.
