Ozone Depleting Substances - The amount of ozone-depleting substances discharged or leaked to air increased from 0.35 tonne of chlorofluorocarbon (CFC) equivalent in the previous reporting period to 0.42 tonne CFC equivalent in the current reporting period. This was mainly due to a leak in the refrigeration and air conditioning system at a petroleum site (which has since been corrected). We continue to phase out the use of ozone-depleting substances across our operations in compliance with legislative requirements.

Emissions Management: The key air emissions generated by the Company's activities include greenhouse gas emissions, oxides of sulphur and nitrogen, ozone-depleting substances and fluoride.

Primary greenhouse gases of concern to us are carbon dioxide (a product of energy use and the use of fluxes) and methane (which occurs at coal mines and from oil and gas production facilities). Less significant are emissions of perfluorocarbons associated with our Aluminium CSG.

Land, 4th paragraph: The total footprint of land owned, leased and/or managed by our operations was 1.73 million hectares, of which one per cent was for infrastructure (buildings and offices, processing plants, roads and rails), two per cent for mining, four per cent for supporting infrastructure, and four per cent for on-going exploration. Approximately 26 per cent of land is intended for future operation/expansion, 40 per cent is designated as buffer zones and areas not intended/planned for operation, and the remaining 23 per cent is for other purposes. In addition, our Exploration group holds approximately 29 million hectares of exploration rights, leases and permits.

Environment > Our Approach > Biodiversity

3rd paragraph - Without systematic assessment and management, from exploration through to post-closure land use, there are potential risks that biodiversity values and impacts will not be recognised. The majority of our sites have embedded biodiversity considerations into their overall environmental management system, and many are actively engaged in biodiversity-related programs. For example, our Worsley Alumina operation in Western Australia is developing an enhanced wildlife corridor through the Saddleback Timber Reserve and the George Forest Block. In addition some sites, such as Escondida (Chile), form partnerships with academia and research institutes to improve biodiversity outcomes.

'Land rehabilitation programs at Cerrejón and Mt Arthur Coal show the value of mine closure planning, 13th paragraph: Also under the land management plan, a bund (embankment) is being constructed from overburden on the boundary of the mine site. At 40 to 50 metres in height, the bund is designed to create a visual screen between the town of Muswellbrook and the mining operation. Shortly after the placement of the overburden, the bund is being vegetated with a combination of pasture grass and native trees so that it blends in with the surrounding rural landscape.
