Greenhouse gas emissions

emissions
Energy use has a direct impact on Accor’s carbon footprint, in
particular through hotel boilers, electric appliances and employee
travel. The environmental footprint study determined that the
Group as a whole emits close to 3.7 million tonnes of life-cycle
CO
2
equivalent per year, nearly two-thirds of which comes from
hotel energy use (mainly electricity). It also revealed that upstream
farming operations account for nearly 15% of our greenhouse
gas emissions. Meat and dairy products alone are responsible for
nearly half of the greenhouse gas emissions associated with food
services (27% and 20% respectively), even though they account
for less than 15% of sourced food volumes.

The change in CO
2
emissions over the three-year period may be
explained using the same reasoning as for the energy use ratios:
ƒƒ
for the total consolidated scope of reporting, CO
2
emissions per
available room rose by 22.7% between 2011 and 2013;
ƒƒ
at comparable scope of reporting, they rose by just 0.6% over
the period;
ƒƒ
once adjusted for weather conditions and occupancy rates, the
carbon ratio declined by at least 1% between 2011 and 2013,
primarily due to the 15% increase in hotel heating needs over
the period, which also drove the 0.3% increase in energy use.
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
.
Ozone-depleting cooling fluids
Cooling liquids in hotel air conditioning and cooling systems may
leak and release gases with a particularly high global warming
potential (GWP). Moreover, theremay be a risk of coolant evaporation
during maintenance operations or as a result of an accident. The
2011 environmental footprint study showed that such leaks and
evaporation account for a minor 2% or so of our carbon footprint.
In 2013, 69% of Accor hotels were using energy-efficient air
conditioning units or heat pumps and 94% annually ensure that
pipes carrying hot/cold fluids are leak-proof.
