Santos’ carbon emissions Direct liability (Scope 1 emissions): Direct operated reported emissions of ~3.6 mtCO2e for 2010-11 Electricity purchases (Scope 2): Indirect emissions from operated sites ~0.04 mtCO2e These costs associated with scope 2 emissions will be passed through to Santos via higher electricity prices Customer use of natural gas (Scope 3): Embodied emissions of ~16.6 mtCO2e (assumes that all products are combusted) Embodied emissions from natural gas are transferred to the buyer through an OTN (obligation transfer number) Supplier is not liable for embodied emissions in liquid fuels. Depending on its use, an equivalent carbon price may be applied for the user of the liquid fuels

Overall impact Treasury modelling suggest that carbon pricing will increase aggregate consumer prices in 2012-13 by 0.7 per cent A further 0.2% increase is expected in 2015-16, once emissions trading starts, bringing the total CPI impact to 0.9 per cent over 4 years Source: Treasury modelling, 2011

19. © Chartered Secretaries Australia Ltd 2012 Prepared and presented by Santos Limited. Electricity Treasury modelling estimates that household electricity prices will increase ~10%. The majority of this increase is attributed to electricity generation. The average carbon intensity of the National Electricity Market (NEM) is ~0.9tCO2e/MWh equating to the increase of ~$20/MWh In theory, impact on electricity costs will vary based on the carbon intensity of the source, though many other factors at play Source: Securing a clean energy future: The Australian Government’s Climate Change Plan, 2011

Liquid Fuels Households and on-road business use of light vehicles will not face a carbon price on fuel Rail, shipping, domestic aviation, off-road transport (eg on mine sites) and non transport liquid fuels will face an effective carbon price, through changes to the current fuel tax regime Heavy on-road vehicles will not face a carbon price, but the Government intends to apply an effective carbon price on heavy on-road vehicles from 1 July 2014 There is a mechanism to ‘opt-in’ under the carbon pricing scheme rather than the fuel tax system, but Santos does not see any benefits in this Source: Clean Energy Plan, Transport Fuels factsheet, DCCEE 2011
