They also believe there is a 60 per cent probability that 2007 will be as warm as, or warmer than, 1998 — which was the world’s hottest year since records began in 1850. This information represents a warning that climate change is happening around the world. The world’s 10 warmest years have all occurred in the last 12 years. The leading international body of climate scientists has already agreed this is evidence of humans accelerating global warming. The BMO’s previous 2001 report concluded that global temperatures could rise by between 1.5 and 5.8 degrees over the next century without significant cuts in greenhouse gas emissions, particularly from burning fossil fuels such as coal and petrol. Scientists have repeatedly warned that the longer the world delays making those cuts, the greater the risks of more extreme weather, including droughts, bushfires and coastal flooding. A recent World Meteorological Organisation report found that 2006 was the sixth hottest on record and was marked by drought and heavy flooding in the Horn of Africa, record bushfires in the US, torrential rain in the Philippines, shrinking sea ice in the Arctic and the warmest autumn in Europe. At the same time, the Australian Bureau of Meteorology released its annual Climate Statement which confirmed that Australia’s temperatures are getting warmer slightly faster than the global average and we know that of Australia’s 20 hottest years, 15 have occurred since 1980. Make an Impact Australian households generate almost one-fifth of Australia’s greenhouse gas emissions through everyday activities. Alcoa and Greening Australia have partnered to develop a greenhouse footprint reduction program for the families of Alcoa employees and their immediate communities. Known as Make an Impact, the program includes access to a greenhouse calculator and a kit featuring a range of tips on how to lower energy and water consumption and more effectively manage waste. > Switch to Green Power accredited electricity Eliminates household emissions from electricity > Use energy efficient whitegoods Up to 50% reduction in household emissions from electricity > Use a triple-A rated showerhead Up to 12% reduction in household emissions > Use energy-efficient light globes Up to 10% reduction in household emissions > Check the fuel efficiency of your next car Up to 70% reduction in transport emissions Plan ANIMALS OF THE ANGLESEA HEATH SOUTHERN BROWN TREE FROG (Litoria ewingi) Adult length: Description: Distribution Habitat: Call: 25-45mm tadpoles are pale golden-yellow to dark grey with clear fins; adults have pale fawn, cream, orange, or light brown sides endemic to south-eastern Australia adults can be found in all habitat types, even in the gardens of suburbia, eggs and tadpoles can be found in ponds, dams, lakes and flooded roadside ditches a series of rapid harsh, whirring pulsing notes repeated 5-15 times - ‘creeeeeee creee creee cree cree cree’ - first note is the longest Frogs and climate change: Frogs need water to breed and any reduction or changes in rainfall could reduce the ability of these animals to reproduce. Higher temperatures contribute to the drying out of breeding pools and to the deaths of tadpoles and eggs. Drier conditions also kill adult frogs, which lose internal water through their permeable skin SOUTHERN BROWN TREE FROG ANGLESEA ENVIRONMENT REPORT JANUARY 2007 LAND RAINFALL (mm) Month JAN FEB MAR APR MAY JUNE JULY AUG SEPT OCT NOV DEC TOTAL 2007 Rainfall 40.0 19.6 7.3 37.1 129.4 17.0 40.8 26.0 32.8 15.8 15.4 29.0 40.0 1968-2006 Average 44.6 43.9 42.5 53.5 59.3 60.8 61.1 67.0 69.3 73.6 54.1 44.2 44.6 130 7 0 0 .0 0 120 6 0 0 .0 0 110 100 5 0 0 .0 0 90 80 4 0 0 .0 0 70 60 3 0 0 .0 0 50 40 2 0 0 .0 0 30 20 1 0 0 .0 0 10 0 0 .0 0 WATER TOWN WATER USE (ML) 2000 2006 2007 JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC Process 23.9 11.0 0.7 0.7 0.7 0.8 1.1 0.9 0.6 0.6 0.7 0.6 1.3 1.5 1.5 Amenity2 . 0 11.6 3.8 0.3 0.3 0.3 0.2 0.4 0.7 0.2 0.4 0.4 0.3 0.3 0.3 0.1 4 0 .0 1 .8 3 5 .0 1 .6 3 0 .0 1 .4 2 5 .0 1 .2 2 0 .0 1 .0 0 .8 1 5 .0 0 .6 1 0 .0 0 .4 5 .0 0 .2 0 .0 0 .0 2000 2006 2007 JA N FE B M A R A P R M A Y JUN JU L A UG S E P O C T NO V D E C AIR GREENHOUSE GAS (GHG) TOTAL (Mt) & GHG EMISSION EFFICENCY (t/MWh) GHG Mt GHG t/MWh 1990 2000 2001 2002 2003 2004 2005 2006 2007 1.42 1.23 1.27 1.50 1.45 1.47 1.31 1.49 1.49 1.34 1.24 1.19 1.21 1.21 1.20 1.21 1.20 1.20 2 1600000 1 .8 1400000 1 .6 1 .4 1 .2 1200000 1000000 1 800000 0 .8 600000 0 .6 400000 0 .4 0 .2 0 200000 0 ANGLESEA ENVIRONMENT REPORT JANUARY 2007 environmental improvement Environmental Management Targets January 2007 Total Forecast 2007 Target Reportable Environmental Incidents 0 0 0 0 Monthly EHS ASAT Audit Completion (%) 100 94 100 90 Air Emission Targets January 2007 Total Forecast 2007 Target Ambient SO2 ( no. readings > 210ppb) 0 0 0 0 Stack SO2 (no. hrs > 100kg/min) 0 0 0 0 SO2 Load Reductions (lost MWh) 1121 1121 13452 N/A GHG Efficiency (t CO2 e/MWh) 1.20 1.20 1.20 1.20 Opacity (10 min av > 0.25g/m normal operation) 0 0 0 0 Water Targets January 2007 Total Forecast 2007 Target Town Water (ML) 0.7 0.7 8.4 14.2 Bore Water (ML) 274 274 3288 2667 Waste Targets January 2007 Total Forecast 2007 Target Waste to Landfill (t) 0.0 0.0 0.0 9.0 Solid Prescribed Waste to Landfill (t) 0.0 0.0 0.0 0.0 3 Mine Rehabilitation Targets 2007 Total 2007 Target 2006 Area Cleared (ha) 0.0 3.5 2006 Area Rehabilitated (ha) 0.0 > 3.5 2005 Mine Rehabilitation Species Richness (%) N/A 100 OUR ENVIRONMENT AND OUR EMPLOYEES.. Climate Change is a very topical issue. What’ s What’s Alcoa’ s position on this subject? Alcoa’s Alcoa has a long standing position of promoting realistic and effective policy responses to climate change. And at a time when the debate is heading in Australia toward a serious discussion on emissions trading it is important industry is ready and able to contribute constructively to both the debate and implementation of solutions. Alcoa of Australia supports the introduction of a properly designed emissions trading scheme, including a national scheme, that includes all major emitters and sectors to ensure greenhouse reductions are achieved. What activities can employees undertake to help be part of the solution? Alcoa has teamed with environmental organisation Greening Australia, to equip employees and their families to cut Australia’s domestic greenhouse emissions by around 21,000 tonnes a year. I encourage all employees to log on to www.alcoa.com.au/makeanimpact and see what they and their families can do to make an impact. ...KYLIE CIRAK 5
