Frequently asked

Barclays vs HSBC Holdings plc, answered.

Which is more sustainable, Barclays or HSBC Holdings plc?

Barclays is more sustainable according to SINK's open sustainability index, scoring 39/100 vs HSBC Holdings plc's 35/100 — a difference of 4 points.

What is Barclays's SINK sustainability score?

Barclays scores 39/100 on the SINK sustainability index (Below expectations). Barclays is Europe's largest fossil fuel financier at $35.4B in 2024 and is actively lobbying against UK sustainable finance regulation. Its operational emissions reductions are genuine but largely driven by renewable certificates rather than physical cuts. The bank's core environmental impact—financed emissions—is increasing, not declining, making climate commitments greenwash.

What is HSBC Holdings plc's SINK sustainability score?

HSBC Holdings plc scores 35/100 on the SINK sustainability index (Below expectations). HSBC rolled back its net-zero target by 20 years in 2025, exited SBTi validation, and continues financing fossil fuel expansion at nearly 3:1 the rate of green finance. An ASA-upheld greenwashing ruling, active lobbying against climate policy, and policy weakening across energy and thermal coal expose systematic misalignment between public commitments and actual financing behaviour.
