Discharges and treatment
The Group’s environmental impact study (updated in 2014) looked
at the impact its hotel operations may have on groundwater quality.
This impact is assessed in terms of the eutrophication phenomenon
that characterizes deterioration in an aquatic environment. In the
sea, eutrophication is measured as nitrogen saturation, expressed
in kilograms of nitrogen equivalent (kg N-eq). In rivers and lakes,
it is measured as phosphorous saturation, expressed in kilograms
of phosphorus equivalent (kg P-eq). On a life-cycle basis, marine
eutrophication as a result of Accor’s hotel activities represents
4,569 kg N-eq and freshwater eutrophication 10,345 kg P-eq.

The environmental impact study shows that nitrogen saturation
arises chiefly (78%) from the farming activities behind the provision
of Accor food services, and from livestock farming activities in
particular, withmeat, milk and eggs accounting for 66%. Phosphorous
saturation arises chiefly (96%) from generation of the energy used
by Accor hotel activities, the bulk of this (95.6%) being from nuclear
Accor can reduce the negative impact on groundwater quality by
ensuring that all hotel wastewater effluent is systematically treated,
either by connection to a collective treatment plant (such as amunicipal
treatment plant), or onsite in an independent treatment plant.
More environmentally sensitive products
The extensive Groupwide use of eco-labeled cleaning products
sourced from a single certified supplier (see page 52) has significantly
reduced our impact on the environment.
In addition, the Mercure, Novotel, ibis Styles and ibis brands, for
example, now offer complimentary items certified with the EU
Ecolabel, Ecocert or Nordic Ecolabel.
2.5.4. LOCAL ENVIRONMENTAL IMPACTS
Accor assessed its biodiversity footprint for the first time in 2014,
evaluating the impact of its activities on ecosystems (i.e. species
and their habitats). It was estimated at 4 billion pdf.m
indicator used to measure biodiversity footprint is expressed in
.y» – i.e. the «potentially disappeared fraction of species»
over a unit of surface area (a square meter) over a unit of time
(a year). For example, one pdf.m
.y corresponds to the elimination
of all biodiversity over a square meter of primary forest and
.y corresponds to the destruction of one square meter
of secondary forest.
The Group’s biodiversity footprint stems, to a very large extent
(77%), from the farming activities behind the provision of Accor’s
food services. This is primarily because most of the impacts on
biodiversity are a direct consequence of land use (and therefore
deforestation) and, for farming operations, the use of pesticides.
The Group’s impact on biodiversity from construction and renovation
is moderate (13%), because the great majority (75%) of Accor
Group hotels are located in urban and suburban areas. Pressure
on biodiversity arising from hotels’ energy use is estimated at 8%.
