Carbon pollution back on the agenda
It seems that the Australian Government has finally recognised the need to reign-in carbon pollution and is looking for ways to meet its targets. Some businesses have been addressing this issue for a while. Freeranger Eggs at Grantville, near Phillip Island is an example of sustainable farming. The farm management plan takes a three pillars approach to how the farm operates. Animal welfare is one pillar, but equally important are land sustainability and food safety. Despite all the political bickering in Canberra over emissions trading scheme targets, Freeranger Eggs has been getting on with mitigating the impact of carbon emissions. The farm's carbon footprint is limited by imposing a food miles policy for deliveries, using recycled materials and equipment whenever possible, utilising solar power and mechanical processes and an effective waste reduction programme. As a result, the 1500-chook farm generates only about 60 tonnes of CO2 each year. But it is better than carbon neutral, it is carbon positive. The average organic matter in soil tests was 4.1 per cent in 2004, in 2006 it was 6.0 per cent, and in 2009 it was 7.9 percent. Calculations based on 2-inch deep samples, show that over those five years the farm sequestered about 14 tons of CO2 per acre or four tonnes of carbon per acre on the grasslands. Further testing and calculations have not been carried because there has been a total lack of interest in the results.
