REDUCE IMPACT ON CLIMATE CHANGE AND GHG EMISSIONS

Although emissions reduction in Singapore is voluntary, we undertook a more comprehensive carbon footprinting exercise in FY2012 which increased the scope of our greenhouse gas (GHG) emissions calculations⁴. Our GHG emissions now include the fleet of contractor vehicles and wider property coverage to provide a more accurate picture of Singtel’s emissions. We intend to continue the development of a more robust strategy in the next financial year.

The emissions factors for purchased electricity in Singapore between 2009 and 2011 were updated in April 2012 by the National Environment Agency. These updated factors have been used in this report. For consistency, we have restated the figures over the period FY2010 to FY2012 to ensure comparisons are more meaningful taking into account these methodological changes.

The full extent of aspects included in emissions calculation is shown in the table below.

Our main source of greenhouse gas (GHG) emissions is Scope 2 electricity purchased directly from the national power grid and is the main focus for the reduction of our carbon footprint. Our net overall carbon equivalent emissions from this indirect energy are 175,324 tCO₂e. The energy conservation programmes undertaken in FY2012 have contributed to a decrease of 2,245 tCO₂e from the previous year.

Our Scope 1 GHG emissions, contributed mainly by refrigerant use, are 6,641 tCO₂e
in FY2012. This represents a slight decrease of 162 tCO₂e from the previous year. As part of our commitment to phase out ozone depleting refrigerants and those that have high global warming potentials (GWPs) and reduce the carbon intensity associated with air-conditioning and chiller systems, we awarded a contract to a vendor who uses R134a refrigerant gas as the cooling medium instead of the ozone depleting R123 coolant.

The Scope 3 GHG emissions were dominated by air travel at 3,064 tCO₂e, representing 79% of our disclosed Scope 3 emissions. We continue to encourage the use of video and telephone conferencing to reduce the overall need for business air travel. Scope 3 emissions also include the use of contractor vehicles for the first time.

⁴ The equivalent CO₂ emission for electricity use are calculated based on the updated 2009, 2010 and 2011 operating margin grid emission factors from the National Environment Agency in Singapore. Direct emissions are calculated using the 2010 Guidelines to DEFRA / DECC’s GHG conversion factors for company reporting
(Annex 1). Other indirect emissions are calculated using the 2010 Guidelines to DEFRA / DECC’s GHG conversion factors for company reporting (Annex 7)
