How we identify and prioritise climate-related risks
To assess transition risks, we engaged
with each operating business to
better understand the preferences
of our customers, suppliers and
employees and the challenges they
face in tackling climate change. The
outcome was factored in during the
risk identification process. Each risk
was discussed and scored based
on the probability and magnitude
of potential financial impact, and
the multiplication of the two scores
determined the materiality of the
risk. Through this process, the
most material risks were identified.
Those risks that were deemed to
be quantifiable were included in
the financial modelling. Existing
mitigations and progress made
were also factored in during the
quantification process. Cost and
benefit analysis for the mitigations
of each quantifiable risk was carried
out. A 10-year discounted cashflow
forecast was modelled for both 2DS
and BAU scenarios, using a discount
rate equalling the Group’s weighted
average cost of capital. .
For physical risks, we used the WTW
Climate Diagnostic Analytical Tool
to help us with scenario analysis.
We assessed our resilience in a time
horizon between 10-80 years for
relatability with asset lifespan, as
recommended for TCFD. The WTW
Climate Diagnostic Analytical Tool
considered insured asset value and
combined exposure to extreme
weather events (acute risks) and
to gradual changes in weather
patterns (chronic risks) for each of
our 82 facilities globally, including
warehouses and offices. Based on the
insured asset value and risk exposure,
each site scored between 1 and 5
(5 being the highest risk). For those
with the highest scores, mitigation
plans were drawn up, and associated
costs were assessed and factored into
the scenario financial models.
Once the climate-related risks were
identified and prioritised, the financial
impact of the key risks up to 2030 was
modelled and assessed for both '2 degree' and 'business as usual' scenarios. The key climate
risks, mitigation plans, and the net
financial impact in both scenarios
were presented and discussed at
the Group Management Committee (GMC) before being reviewed by
the Sustainability Committee, which
also included the Chairs of the Audit
Committee and Remuneration
Committee.
How we manage climate-related risks
We use the scenario analysis to inform
our decision-making in the following
areas:
- Strategic and financial planning
- Capital investment
- Acquisition suitability assessment
- Goodwill impairment assessment
- Insurance
- Lease renewals and procurement
of new leases
Climate-related risks are managed as
part of the Group risk management
process, alongside other strategic
and operational risks and, as with all
matters in the Group Risk Register,
these risks are reviewed annually.
Action plans to mitigate such risks
are managed and reported at Group
level, whereas the responsibility for
implementing the plans is delegated
to the management of the operating
businesses.
The GST conducts annual reviews with
operating business management
at the end of each financial year
regarding progress against their
ESG objectives. This is then reported
to and discussed with the GMC
and Sustainability Committee. The
operating businesses report on ESG
progress, including carbon reduction
actions, in quarterly business reviews
chaired by the divisional heads. The
GST also provides progress updates to
the Sustainability Committee at each
Committee meeting.
Climate-related risks and mitigation
progress are monitored by the Risk
and Internal Audit team on an ongoing
basis, which updates the Audit and
Risk Committee at each meeting.
