21 AGL Energy Limited 2011 Annual Report 1 Figures refer to the capacity and/or sent-out greenhouse gas intensity (scope 1 and scope 2) of electricity generation assets over which AGL has operational control, regardless of who owns  the asset. Assets where AGL has rights to the electricity output only are not included. Australia-wide scope 2 greenhouse gas emissions intensity figure is from the National Greenhouse  Accounts (NGA) Factors published by the Department of Climate Change and Energy Efficiency, July 2011 (latest estimate is 0.91 tCO2e/MWh). As an energy company, the most effective way we can contribute  to greenhouse gas emission reduction is by expanding our  investments in renewable energy and low-emission power  generation to reduce the greenhouse intensity of energy that  we produce for our customers. > Expedited development and implementation of a national  emissions trading scheme which uses broad, long-term  greenhouse gas emission reduction targets as its goal > Deployment of renewable technologies through a single  national clean energy obligation > Amalgamation of all existing State-based energy efficiency  obligations into a single national energy efficiency obligation > Appropriate adaptation measures so that Australia is not  adversely affected by existing atmospheric concentrations  of greenhouse gases. AGL has consistently advocated for: Carbon Risk Sustainable Generation Sources The greenhouse intensity of AGL’s operated generation assets  compared to the market average helps to measure how well AGL  is positioned to manage the risk of regulatory intervention through  a carbon price. The carbon intensity of AGL’s operated generation portfolio  decreased this year, due to a larger proportion of electricity  generation from AGL’s operated wind and hydro generators,  which have very low greenhouse gas emission intensities. AGL also uses three additional approaches for measuring and  communicating greenhouse gas performance. The Operational  Footprint, Equity Footprint and Energy Supply Footprint provide  a complete account of the annual greenhouse impacts of AGL’s  operations, investments and the energy supplied to our 3.29 million  customers, and will be available in the AGL 2011 Sustainability  Performance Accounts. In May 2011, AGL commenced operation of the 132 MW AGL  Hallett 4 Wind Farm, increasing AGL’s operated renewable  generation capacity to 1,205 MW. As of 30 June 2011, AGL has an additional 540 MW of renewable  generation under construction, as well as a pipeline of further  renewable and gas-fired generation development opportunities.
