UBS has published its 2025 Sustainability Statement 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. The Swiss bank described the figures as evidence that its near-term operational decarbonisation programme is advancing well ahead of the 2035 net-zero target it has set for its own operations, a commitment that covers all electricity consumption, heating, and business travel within its direct control.
The filing also records an 83% reduction in financed fossil-fuel emissions since 2021, alongside a 55% cut in the intensity of emissions attributable to its power-generation lending and investment 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 — the five sectors the bank has identified as the most significant contributors to its Scope 3 financed emissions base.
RENEWABLE ELECTRICITY AND OPERATIONAL PROGRESS
The near-total shift to renewable electricity, at 99.7%, stands as one of the more sharply defined operational milestones in the statement and is a figure that banks of UBS's scale typically struggle to achieve uniformly across dozens of jurisdictions. Energy procurement is complicated by differences in national grid compositions, the availability of credible power-purchase agreements, and the varying quality of energy-attribute certificates across markets. The bank did not disclose the precise split between physical renewable supply and attribute certificates, a distinction that sustainability analysts commonly scrutinise when assessing whether a near-100% renewable electricity claim reflects genuine additionality or accounting-led compliance.
The 48% Scope 1 and 2 reduction is measured against UBS's 2023 baseline, a reference year that itself reflected the expanded footprint of the bank following the government-facilitated acquisition of Credit Suisse, which added significant office, data-centre, and branch infrastructure to UBS's estate. The fact that the bank has achieved a near-halving of direct operational emissions across that enlarged estate in roughly two years is the context in which management is presenting the result. Operational decarbonisation at this pace typically requires a combination of energy efficiency investment, procurement restructuring, and site-level consumption management.
FINANCED EMISSIONS AND SECTORAL TARGETS
The 83% decline in financed fossil-fuel emissions since 2021 is the headline figure for UBS's Scope 3 portfolio progress and reflects changes in both the composition of the bank's lending and investment book and, in some cases, the performance of underlying borrowers. The 55% fall in power-generation financed emissions intensity suggests that as well as reducing absolute exposure to fossil-fuel producers, UBS has also improved the carbon efficiency of the clients and projects it continues to finance within the energy transition space, channelling capital toward lower-carbon electricity generation assets rather than high-emission thermal plant.
UBS's 2030 sectoral targets span five industries and are expressed in both absolute and intensity terms, allowing for comparisons that account for shifts in the overall size of lending portfolios. The bank's net-zero target for its own operations is set at 2035, five years ahead of the 2040 or 2050 dates more commonly adopted by large financial institutions. Progress against the 2030 sectoral targets and the 2035 operational net-zero commitment will be tracked in successive annual sustainability statements, giving investors a consistent longitudinal record against which to assess UBS's delivery of its published climate strategy.
