Halifax scores 46/100 (Making progress) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.

That places Halifax joint 225th of 809 companies scored, and 10th of 46 in Financial Services / Banking.

Halifax's parent, Lloyds Banking Group, reports comprehensive operational emissions and 100% renewable electricity, but financed emissions dwarf these efforts at 32.8 MtCO2e. A December 2024 greenwashing ruling and InfluenceMap's finding of 3.1:1 fossil fuel to green financing ratio expose a fundamental contradiction between net-zero rhetoric and actual capital allocation.

    Founded-year rule, score unchanged. founded 1853 -> empty: Halifax is not a company ("Halifax is a division of Bank of Scotland plc", halifax.co.uk). Halifax plc's business passed to Bank of Scotland plc (SC327000, incorporated 2007-09-17, https://find-and-update.company-information.service.gov.uk/company/SC327000); the former Halifax plc (02367076, renamed Halifax Limited) was dissolved 2025-03-05 (https://find-and-update.company-information.service.gov.uk/company/02367076). Bank of Scotland's 2007 creation is not Halifax's, so founded is left empty (Haydn 2026-10-14). Description: removed the contradictory "founded in 1749"; now "its roots go back to 1853". bioVerifiedBy manual:halifax-1853-permanent-benefit-building-society -> manual:halifax-division-of-bank-of-scotland-sc327000.
