Scope of reporting
The scope of reporting covers all of the owned, leased or managed
Accor-brand hotels open at December 31 of the reporting year,
except for:
ƒƒ
hotels that are being gradually integrated into the Accor network
or are incapable of measuring use:
yy
hotels that joined the network after September 15 of the
reporting year,
yy
new acquisitions during the reporting year that are not under
an Accor banner,
yy
hotels closed for renovation during the reporting period,
yy
Thalassa sea and spa facilities, whose data are often reported
with their host hotel’s;
ƒƒ
independently operated units or structures and franchised hotels:
yy
ibis
budget
, hotelF1 and Formule1 hotels operated under
commission-based management contracts,
yy
Mercure Appartement in Brazil,
yy
ancillary in-hotel activities, such as retail outlets and residential
units, that are not managed by Accor (assuming their data can
be clearly segregated).
Indicators
ƒƒ
Energy use:
yy
reported energy use is the final amount of energy used by
the hotel;
yy
reported energy is the total amount of energy used over the
year by the hotels, regardless of source (electricity, gas, etc.)
or purpose (lodging, food services, etc.);
yy
total energy use is expressed in MWh;
yy
fuel energy is calculated on the basis of each unit’s heating
value (HV);
yy
use data reported by the hotels are expressed by type of energy.
ƒƒ
Water use:
yy
reported water use is the total amount of water used over
the year by the hotels, regardless of purpose (food services,
grounds watering, etc.);
yy
water from hotel pumping facilities is also measured, if they
are metered;
yy
recycled rain or wastewater is measured, if the facilities are
metered;
yy
total water use is expressed in cubic meters.
ƒƒ
Greenhouse gas emissions:
yy
direct emissions correspond to fuels burned at the hotels and
indirect emissions correspond to the electricity used by the
hotels, and the heat and air conditioning supplied by urban
heating and cooling networks;
yy
energy use is converted using the latest emission factors of
the GHG Protocol (available online at
);
yy
total greenhouse gas emissions are expressed in tonnes of
CO
2
equivalent.
Data collection and control
Each hotel enters its monthly water and energy consumption data
and validates them in the OPEN reporting application.The data are
then checked by the country or regional organization and again at
Group level over the first 11 months of the reporting year.They are
re-checked over the entire twelve months at each level (country/
region and Group).
Hotel carbon emissions are calculated from previously reported
energy use data, as follows:
ƒƒ
direct emissions correspond to the gas and fuel oil burned in
hotel boilers;
ƒƒ
indirect emissions correspond to the electricity used by the
hotels, as well as the heat and air conditioning supplied by urban
heating and cooling networks.
Greenhouse gas emissions for both power generation and fuel use
are calculated on the basis of Greenhouse Gas Protocol initiative
coefficients
.
Renewable energies
Solar production of hot water (expressed in GWh) is calculated
under the following assumptions:
ƒƒ
if 2013 figures on solar panel surface area and production are
available, along with 2014 figures on solar panel surface area,
then 2014 production = 2014 panel surface area x 2013 production
/ 2013 panel surface area;
ƒƒ
if figures are only available for the 2014 panel surface area, then
2014 production = 2014 panel surface area x 500 kWh/m
2
;
ƒƒ
if figures are only available for the 2013 panel surface area and
2013 production, then 2014 production = 2013 production;
ƒƒ
if no data is available for 2014 or 2013 (panel surface area,
production), then 2014 production = 0.
