Basis of preparation – UBS Europe SE climate- and
nature-related metrics
The basis of preparation provides
information on the definition, scope,
methodology and assumptions used to
calculate
and
report
2024
metrics
that
UBS
discloses.
Each
metric
is
prepared
in
accordance
with
an
internal
procedure
that
specifies processes, reporting
systems, data sourcing,
roles and responsibilities,
methodologies and controls.
The design
of these metrics considers prevailing reporting frameworks and industry best practices. UBS regularly reviews the metrics
that are disclosed and may make updates or changes in line with its business priorities, regulatory requirements, industry
standards and market practices.
Theme
Sustainability and climate risk
Metric(s)
Carbon-related assets (USD m)
Legal entity
UBS Europe SE (standalone)
Definition
and method
Carbon-related assets are defined as concentrations of
credit exposure to assets tied to the four non-financial
groups as defined by the
Task Force on Climate-related Financial Disclosures (TCFD) (using Global Industry Classification
Standard, GICS). These four groups are:
(i) energy; (ii) transportation; (iii) materials and
buildings; and (iv) agriculture, food and forest products. Recognizing
that the term
carbon-related assets is currently not well defined, the
TCFD encourages banks to use a consistent
definition to support comparability.
The metric is calculated for UBS Europe SE (standalone)
on the total on-balance sheet loans and advances
to customers and off-
balance sheet guarantees and irrevocable loan commitments
(within the scope of expected credit loss) and is
based on standalone IFRS
numbers.
The carbon-related assets metric is the total exposure
of assets in the four non-financial groups as
defined by the TCFD in its expanded
definition published in 2021. UBS defines
carbon-related assets through industry-identifying attributes
of the firm’s banking book. It
also includes the four non-financial sectors
addressed by the TCFD, including but not limited
to, fossil fuel extraction, carbon-based
power generation, transportation (air, sea, rail and auto manufacture), metals
production and mining, manufacturing industries, real
estate development, chemicals, petrochemicals,
and pharmaceuticals, building and construction
materials and activities, forestry,
agriculture, fishing and food and beverage production,
also including trading companies that
may trade any of the above (e.g. oil
trading or agricultural commodity trading companies).
This metric is agnostic of risk rating, and therefore
may include exposures of
companies that may be already transitioning or
adapting their business models to climate risks,
unlike UBS climate-sensitive sectors
methodology, which takes a risk-based approach to defining material exposure
to climate impacts. Economic sectors
are classified
according to the Group Industry Code 2.0 (GIC2.0) which
comprises a hierarchical structure, and further dissected
using the heatmap
segmentation. Internal UBS GIC2.0 sectors
/ subsectors are utilized.
Theme
Sustainability and climate risk
Metric(s)
Total exposure to climate-sensitive sectors, transition risk (USD m)
Legal entity
UBS Europe SE (standalone)
Definition
and method
Sustainability and climate risks may manifest
as credit, market, liquidity and / or non-financial risks
for UBS, resulting in potential
adverse financial, liability and / or reputational impacts.
These risks extend to the value of investments
and may also affect the value of
collateral (e.g. real estate).
Climate risks can arise from efforts to mitigate climate
change (transition risks). Transition risks from efforts to address a changing
climate may contribute to a structural
change across economies and can consequently
affect banks and the stability of the broader
financial sector through financial and non-financial
impacts.
The metric is calculated for UBS Europe SE (standalone)
for banking products, traded products and issuer risk.
For banking products, the metric is calculated on total
on-balance sheet loans and advances to customers
and off-balance sheet
guarantees and irrevocable loan commitments (within
the scope of expected credit loss) and is based
on standalone IFRS numbers.
For traded products, the metric is calculated on over-the-counter
(OTC) derivatives, exchange-traded derivatives
(ETDs) and securities
financing transactions (SFTs), consisting of securities borrowing and lending, and
repurchase and reverse repurchase agreements.
Issuer risk, also known as tradable single name
exposures, refers to the price and other risks resulting from changes
in the financial
condition of a specific issuer that cannot be
attributed to general market risk. For issuer
risk, the metric is calculated on HQLA assets,
debt securities, bonds and liquidity buffer securities.
In 2024, UBS launched a transition risk rating
model (TR RM), designed to provide a company-level
rating of transition risk, where
input data is available. The model methodology
mainly relies on two inputs: the output of the transition
risk heatmap (TR HM), which
is based on the counterparty’s sectoral classification
and country group, and the Company Transition Assessment Scorecard (CTAS).
CTAS is an internal UBS tool that provides sector-agnostic assessment
of companies, categorizes large, listed
companies based on the
data collected from external providers and summarizes
them into a category that is indicative of
each firm’s stance towards net-zero
alignment. In the TR RM,
the counterparty’s TR HM rating is adjusted
based on the distance between the net-zero
stance of a
company and that of its group’s median via the CTAS. Whenever CTAS does not provide an assessment
for a company, the model
relies exclusively on the TR HM. The coverage of
TR RM depends on CTAS, which in turn, depends on the data
collected from external
providers. Once data is available for a wider set
of companies, the coverage of TR RM is
expected to improve.
The TR HM methodology is based upon
a risk segmentation process, first dividing financing
types and then rating economic sectors
and sub-industry segments that share similar climate-risk
vulnerability characteristics. Climate transition
risk scores and ratings are
assigned to sectors and segments according to their
vulnerability to (i) climate policy, (ii) low-carbon technology risks, and
(iii) revenue
or demand shifts under an immediate, ambitious,
and disorderly approach to meeting the well-below-2˚C
Paris Agreement goal. The
risk ratings can be used to support the identification
of potential climate-sensitive concentrations
and further analysis. The ratings in
the heatmap reflect the levels of risk that would
likely occur under an ambitious transition
(in the short term, 0–3 years) and disorderly
with respect to diversification of policy stringency
across developing and industrialized countries.
The countries are classified as either
industrialized countries ("IC") or emerging
markets countries ("EM"), as per UBS country
risk policy.
UBS derived the methodological approach for
the transition risk assessment from an active collaboration
with the United Nations
Environment Programme Finance Initiative (UNEP-FI) and
Oliver Wyman. Assessments are derived as part of
the 2018–2022
collaboration with the UNEP-FI based on Integrated
Assessment Modelling Consortium (the
IAMC) scenario information along with
academic research supporting risk rating analysis.
The collaboration included development of the
initial TR HM methodology. Since the
original version, UBS has further established
the ratings and risk segmentation process in-house,
reflecting changes in risk profile on
the ground, evolving in-house views on climate
risk materiality, and UBS’s own business footprint.
