BASIS OF REPORTING
Environmental performance parameters
Water
Water consumption and amount of waste water discharge
Waste-water quality
Organic content in effluent after treatment.
Amount of suspended solids, nitrogen and phosphorus
in the waste water
Energy consumption
Consumption of electricity and heat
Atmospheric emissions Emissions of C02, NOx.SOx; refrigerants
(CFCs and (H)CFCs, NH3) that are in use and have been lost;
halons that are in use and have been lost
Solid waste
Hazardous waste, waste-water treatment sludge,
residual industrial waste
Nuisance
Number of complaints
Limitations
The reliability of the data is subject to certain limitations, despite the fact that the
safety and environmental experts at our production units have reported to the best of
their knowledge, in good faith and in accordance with agreed procedures and their
figures have been validated by the Heineken Technical Services unit. Heineken is con
tinuing to work on formulating and applying uniform definitions and instructions for
reporting purposes, in order to improve the accuracy and comparability of the data.
Definitions
Differences in the interpretation of definitions have occurred in some cases. On the
basis of our internal validation findings, we do not expect these differences at the
aggregated level to be greater than ±5% The definitions of effluent and waste-water
treatment sludge volume have been revised in 2001 (see environment report).
Completeness
Reporting was late, incomplete or not received at all in some cases. In orderto provide
a realistic representation of total Heineken's environmental impact, the missing data
have been estimated in accordance with our internal procedures. Some data have been
estimated by our operating companies. It is not always known to corporate office in
which cases this has been done.
