Figure 4. Trend in total GHG emissions, including LUCF (l<strong>and</strong> use change <strong>and</strong> forestry) in GgCO2e<br />

If ICT-related emissions in Ghana followed global averages, then 2.5 per cent of GHG emissions in Ghana<br />

would come from ICT networks <strong>and</strong> devices, including wireline <strong>and</strong> mobile networks, broadcasting networks,<br />

<strong>and</strong> consumer electronic devices (in both homes <strong>and</strong> businesses), <strong>and</strong> this would equate to about 0.6 Mt<br />

CO2e. ICT is included in the energy sector. This estimate does not include emissions from sectors such as<br />

transport <strong>and</strong> manufacturing which are discussed in Section 3.<br />

The sources of ICT-related GHG emissions may be traced from a life cycle assessment (LCA) of ICT devices.<br />

The life cycle phases (for any product or service including tele<strong>communication</strong>s) are defined in ISO14040/44<br />

as:<br />

• Raw material extraction <strong>and</strong> conversion<br />

• Manufacture<br />

• Use (or consumption)<br />

• End-of-life (re-use, recycling of materials, energy recovery <strong>and</strong> ultimate disposal)<br />

Transport <strong>and</strong> energy supply are included in each life–cycle phase.<br />

The proportion of emissions from each phase is illustrated in Figure 5. Every ICT product will have a<br />

different apportionment. A more exact apportionment of emissions for Ghana is recommended for further<br />

study.<br />
