8HOLCIM Integrated Prot & Loss Statement 2022
OUR VALUE ANNEX
Costs for the employer were not taken into
account, since these are already reected in the
nancial section of the IP&L.
For fatalities and injuries, the data was based on
an Australian research group (Safe Work Australia
2015).
11
The data was adjusted for GDP and
ination, based on the VBA’s methodology.
Employee education
Calculated based on the VBA’s methodology,
which takes into account the total hours of training
per country per employee, a country-specic
training coefcient, the expected increase in wage
due to these trainings, the annual turnover rate, the
age of the employees trained and the retirement
age per country. Based on these numbers, the
expected increase in wage was calculated for the
people leaving the organization and based on the
expected number of years to work, the future
enhanced earnings were calculated and
discounted to a net present value.
This approach enables us to estimate the wider
social benets of training (i.e., social benets felt
by our former employees). The benets of training
felt by those people who remain at Holcim will be
visible internally through efciency gains and
increased revenues.
ENVIRONMENTAL DIMENSION
CO
2
own operations
The social cost of carbon (SCC) represents the
current and future economic damages from the
emission of one ton of GHGs. The cost is calculated
by multiplying the tons of absolute gross CO
2
emissions by USD 111 (CHF 106). This gure was
derived using the assumptions below.
The amount of CO
2
considered corresponds to
our absolute gross emissions (Scope 1 and 2) over
a full calendar year. The total tons (t) of CO
2
are
multiplied by its societal value, which we
assumed to be CHF 106.4/ton in 2022.
We acknowledge that there are a large range of
estimates of the CO
2
societal value. As
recommended by the VBA methodology, we based
our gure on a 2012 PWC meta-analysis of
academic literature on the social cost of carbon,
which was USD 78/t (inated to 2022: USD 111.5/t).
Air
The damage costs of PM, SOx, NOx and VOC air
pollutants were based on the VBA method and
applied on a country-by-country basis.
Since the VBA methodology does not include all
the air pollutants relevant to Holcim, additional
sources were used to monetize the impacts of
dioxins and furans and heavy metals. A study
evaluating damage costs based on national
averages for 32 countries, related to health effects
from ingestion and inhalation, was used. The
assumptions on this study are found in the heavy
metal emissions section.
•
Heavy metal emissions: Calculated by
multiplying the emissions in 2022 by a monetary
figure derived using the assumptions below. The
respective values used can be found in the annex.
The damage costs of heavy metal emissions
(Hg, Pb, Cd, As, Cr and Ni) were determined from
a study evaluating damage costs based on
national averages for 32 countries, related to
health effects from ingestion and inhalation
(cancers but also neuro-toxic effects leading to IQ
loss, as well as subsequent loss of earnings
potential for Pb and Hg).
12
The analysis quantied burden, dispersion and
exposure (deposition velocities) to assess uptake
by plants and animals and the impact on the
human body (via consumption of tap water,
agricultural crops or animal products).
The damage costs were then calculated by
multiplying physical impacts by the appropriate
cost:
•
the unit cost for cancer includes medical
expenses, wage and productivity losses, and the
willingness to pay to avoid the pain and suffering
inflicted by the disease
•
the unit cost for IQ includes expenses associated
with remedial learning and loss in potential
lifetime earnings (costs are discounted at 3% but
without consideration given to increases in
willingness to pay with economic growth in
future years).
The study does not consider the effects of
groundwater contamination, adjustment of
ingestion dose to account for food preparation
and the implementation of remedial strategies
(e.g., ltration for tap water) or the potential
contribution of heavy metals and organic
micropollutants to other impacts of ne
particulate matter. Therefore, total impact
attributed to these pollutants can be
underestimated, but data from this study is used
as an approximation to value their impacts.
