We collect performance data on our greenhouse gas emissions as follows:

Scope 1: Emissions from fuel consumption (generally from diesel generators) to operate network base stations that do not have reliable access to national power grids, and for heating, cooling and powering buildings and offices (mainly with diesel and natural gas). We also report emissions from vehicle fuel.

Scope 2: Electrical power consumed by our network, buildings and offices. 

We do not collect emissions data relating to air travel, or on other Scope 3 emissions, such as use of products and supply chain-related emissions. 

The charts below indicate an absolute decrease in both Scope 1 and Scope 2 COe emissions. The Scope 1 reduction is driven by the substantial savings in diesel in Pakistan (and to a lesser extent, Bangladesh) described in the case study here. The Scope 2 reduction results from reduced energy use in several of our larger business units driven by energy efficiency measures, equipment modernization and the sale or sharing of towers. 

 It is challenging to gather highly accurate data on energy consumption for several of our markets and we rely on a mixture of data sources including invoices, by extrapolation from known actual energy performance of different types of base station, and from estimates. The results in the charts and tables below should be interpreted in that context. 

 Approximately 82% of our total carbon footprint relates to operating our network. Within the total energy use is a small amount (0.04%) of renewable energy. This is generated from our 282 solar-powered base stations (2014, 118) and the significant solar arrays on buildings in Bangladesh.

 We operate a fleet of approximately 5,300 vehicles (2014, 5,900), approximately 40% diesel (2014, 36%) and 55% petrol-fueled, as well as four electric cars and approximately 275 vehicles fueled with CNG.
