Containing our impact on the environment
In a 2007 study, research firm Gartner estimates that 2% of
global CO2 emissions are produced by the ICT industry. It is
generally accepted that CO2 emissions contribute to global
warming and climate change. Mobile phones and networks
have environmental impacts at every stage of their lifecycle – from manufacture and use through to disposal. Vodacom
focuses on reducing these impacts at the stages where we
have direct control. Three environmental issues are where
we have the ability to reduce our environmental impact:
- Consumption of resources;
- Placement of base stations; and
- Electronic waste.
As a responsible corporate citizen, Vodacom is committed
to internationally accepted environmental practices and
national regulations. Vodacom SA achieved a rating of 78.5% following an external audit of compliance with
South African Environmental legislation, conducted by Lexis
Nexis Butterworths in August 2008, down from 90.8% in
February 2008. The reduced score can be ascribed to the
bigger sample (75% of Vodacom SA’s operations) covered
by the audit compared to the previous year. Vodacom
SA received one notice regarding non-compliance to
environmental regulations (directive issued in terms of
Section 19 of the National Water Act no 36 of 1998,
Preventing and Remedying the effects of pollution). A
diesel leak was detected from the Techno Park building
into the continuation pond which feeds into the storm water
drainage system. A full clean-up and rehabilitation action
plan was put in place. To prevent any further incidents the
diesel installation was re-engineered.
Vodacom SA’s environmental management system was
certified by an independent agency, Dekra Certification
GmbH, in November 2008. No concerns were raised by
the auditor and Vodacom SA unconditionally retained
ISO 14001 certification.

1Electricity consumption at sites is an approximate value based on the use of averages. Vodacom is working on more accurate consumption measures
Vodacom has a number of initiatives in place to contain,
and ultimately reduce, the consumption of energy and
other resources:
- Reducing energy consumption – A three-year strategic
roadmap setting out targets for reducing energy
consumption and CO2 emissions from base stations has
been formulated, projecting cumulative power savings of
over 80 000 MWh and 70 000 tons of CO2 emissions.
We are likely to make a greater impact at our 3G base
stations, as opposed to our 2G base stations, as
3G installations are more efficient in using power.
Accurate measurement of energy use remains a priority.
- Using renewable energy – Vodacom is experimenting
with the use of renewable energy sources (fuel cells,
solar, wind power) to power our network equipment,
especially during times of peak energy demand. Other
products being developed make use of safer fuel sources
such as methanol/water mixtures.
- “Greening” its buildings – Vodacom has identified
two main areas in which improvements can be made
to existing buildings: better management of water (i.e.
waterless urinals) and energy efficiency (i.e. intelligent
lighting solutions). At the new office building in Durban
we will be installing more energy efficient lighting
and air-conditioning.
- Reducing powered air-conditioning – During 2008,
Vodacom SA installed 280 units that make use of ‘free
cooling’ technology at our base stations, resulting in
a reduction of up to 60% in energy used for cooling.
A further 1 000 such units will be installed during the
current financial year. Free cooling technology has also
been applied to our offices in Midrand, while the design
and layout of our data centres are being improved to
reduce the cooling requirement.
- Improving generator usage – Hybrid systems are being
developed to reduce generator run-time and
fuel consumption.
- “Greening” its catering facilities – Various measures
have been implemented in our catering facilities to
reduce energy use and waste, including the recycling
of cooking oil (approximately 1 400 litres per annum),
management of ‘time in use’ and the collection of food
waste for bio-recycling.
- Reducing water consumption – Water-wise management
techniques are being applied at all gardens and water
features that surround the company’s buildings.
Placement of base stations
Vodacom SA has a policy in place to guide the placement
of base stations, drawing on demographic studies,
research results and customer requests to determine the
most appropriate location for new base stations. This
policy complies with ECNS licence requirements, as well
as with legislation governing the stakeholder engagement
process required before a new base station can be built. As
required by national legislation, independent environmental
impact assessments are conducted for all new site
proposals.
These help protect plant and animal species against habitat
loss, fragmentation and extinction, and prevent erosion and
the destruction of wetlands, vital to the preservation of a
country’s water supply.
Vodacom SA has devised innovative ways to blend base
stations in with the surrounding environment, with 309
of these modified base stations currently in operation.
Examples include locating antennae on existing structures,
painting them to blend in to the background, or disguising
masts as windmills, trees or billboard towers.
Electronic waste
Electronic waste includes network equipment, IT and
handset waste:
- Network equipment waste – Vodacom has not yet
managed to accurately measure network equipment
waste, but has mapped the waste stream and
redesigned the equipment chain to include a formal
system of collection, reuse and disposal.
- IT waste – Vodacom intends to launch an E-waste
recycling programme with our IT vendors that will allow
for the recycling of old equipment in a formalised and
controlled process.
- Handset waste – Handsets sent to our Vodacare outlets
that are beyond repair are collected for recycling.
After sorting for recyclable parts, the handsets are sent for
dismantling and further sorting into component materials
that are either recycled, or disposed of responsibly.
In the year ended 31 March 2009, just over 12 400
cell phones were recycled. In March 2008, Vodacom
SA also introduced a waste disposal process allowing
customers to dispose of their unwanted cell phones and
accessories in an environmentally friendly way.
