28. Chapter 2: The brewer (continued)
Our electricity consumption has decreased from
9.91 kWh per hectolitre in 2004 to 9.59 kWh per
hectolitre in 2005. This total is just above the target
for 2005 of 9.5 kWh per hectolitre. The inclusion
of soft drinks plays an important role in this
reduction. Further savings can be attributed to the
optimisation of a cooling plant compressor in Ama
(Nigeria) and the electricity-saving programme,
which included initiatives such as a new lighting
control system in Sharkia (Egypt). In addition, in
Warka (Poland), the new boiler house consumes
50 per cent less electricity than the old one. The
brewery in Lagos (Nigeria) excluded the electricity
consumption by third parties in line with the
reporting scope, which was not the case in 2004.
Indirect C02 emissions have increased from 3.3 kg
C02 per hectolitre in 2004 to 4.0 kg C02 per
hectolitre in 2005. This reported increase follows
the inclusion of indirect C02 from the purchase of
steam in our figures. Without this effect indirect
emissions would have been slightly lower at 3.4 kg
C02 per hectolitre of beer.
We are committed to save fuel and electricity
through our Aware of Energy programme and
consequently reduce our C02 emissions. Our target
is a 15 per cent reduction over the period 2002 -
2010; to date we have achieved a 3 per cent saving
and will need to make considerable efforts to meet
our 15 per cent target by 2010.
Several of our production units participate in the
European Union C02 emission trading scheme.
For the year 2005 these units received rights for
298 ktons of C02, while 245 ktons were used.
The proportion of renewable thermal energy
utilised has remained stable at 1.5 per cent in
2005. This energy is mainly comprised of biogas
from anaerobic treatment of waste water. The
proportion of renewable electricity was 15 per cent
of the consumed amount in 2005.
Emissions of ozone-depleting substances to air
due to losses from our installations were reduced
from 12.7 tonnes in 2004 to 8.4 tonnes in 2005,
corresponding with 1,050 kg Rll equivalents
in 2004 to 636 kg Rll equivalents. The lower
losses are mainly the result of newly installed
equipment and improvements in our cooling
systems (for example in Bujumbura, Burundi
and Ibadan, Nigeria).
Heineken has been invited to participate in the
'Refrigerants naturally' initiative, which Heineken
has accepted. Greenpeace, along with companies
including Unilever, PepsiCo, Carlsberg and Danone
will exchange information about the development
of systems with alternative refrigerants to move
away from the use of HFCs.
