ENVIRONMENTAL SUSTAINABILITY
Specific thermal energy consumption at the maltings
was 3 per cent lower in 2003 than in 2002, at 2,900
megajoules per tonne.
Specific thermal energy consumption at the soft-
drink plants was ten per cent lower in 2003 at 36.7
megajoules per hectolitre of soft drinks, a contributo
ry factor being the physical separation of the beer
and soft-drink production units at the Pivara Skopje
plant (Macedonia) which enables consumption to be
allocated more accurately. Specific thermal energy
consumption also benefited from a reduction in C02
generation from fossil fuels at the soft-drink plant in
Kinshasa (Democratic Republic of Congo).
Electricity
Electricity is used mainly for refrigeration, water
treatment, driving compressors and other machinery,
liquefying carbon dioxide, lighting and office equip
ment.

Most of the electricity used by Heineken is bought in.
45 per cent of our sites also generate some of the
electricity they consume, using combined heat and
power systems and diesel generators. Six per cent of
our sites are not connected to the grid and generate
all their electrical power themselves.

An analysis of the primary fuel used to generate the
electricity bought in by our sites, using the GRI EN-3
protocol, reveals that 40 per cent of the electricity
we purchase worldwide is generated by coal-fired
stations, 26 per cent by nuclear power stations and
25 per cent a by gas-fired and oil-fired stations.
Around nine per cent of the bought-in electricity
is generated from renewable sources, of which hydro-
power accounts for eight per cent.
Specific electricity consumption by Eleineken's
breweries was two per cent lower in 2003 compared
with 2002, at 10.1 kilowatt-hours per hectolitre of
beer. The brewery in Lagos (Nigeria), where two new
and more efficient packaging lines and a new water-
treatment plant have entered service, accounted for
much of this improvement.
Specific electricity consumption by our maltings
was almost one per cent higher in 2003 compared
with 2002, at 123 kilowatt-hours per tonne. This was
mainly due to the higher demand for refrigeration at
the Ruisbroek (Belgium) plant because of the hot
summer.
Specific electricity consumption by our soft-drink
plants in 2003 was one per cent lower at 5.0 kilowatt-
hours per hectolitre.
