UBS has published its Sustainability Report 2025 as a Form 6-K filing with US securities regulators, disclosing a 48% reduction in Scope 1 and Scope 2 operational emissions against its 2023 baseline and confirming that 99.7% of the electricity consumed across its global estate is now sourced from renewable energy. UBS said it made significant progress in 2025 towards its target of net zero in its own operations (scope 1 and 2) by 2035, which requires a 90% cut in those emissions versus 2023, with the remainder neutralised through carbon removals.
The filing also records an 83% reduction in financed fossil-fuel emissions between 2021 and end-2024 (financed emissions are reported with a one-year lag), alongside a 55% cut in the intensity of emissions attributable to its power-generation lending portfolio. Both metrics are tracked against a set of sectoral decarbonisation targets that UBS adopted as part of its broader 2030 climate commitments, covering Swiss real estate, power generation, fossil fuels, iron and steel, and cement.
RENEWABLE ELECTRICITY AND OPERATIONAL PROGRESS
UBS said the figure is aligned with RE100 guidance; the Bahamas and Qatar were excluded because credible renewable electricity tracking systems are not yet available there.
The 48% Scope 1 and 2 reduction is measured against UBS's 2023 baseline, the year in which UBS acquired Credit Suisse.
FINANCED EMISSIONS AND SECTORAL TARGETS
UBS's 2030 sectoral targets span five industries and are expressed in both absolute and intensity terms. UBS's 2035 target for net zero in its own operations was pushed back from 2025 in March 2025 following the Credit Suisse acquisition; Swiss law requires net zero in companies' own operations by 2050.
