The humble Mars Bar is one of the most popular confectionery items in Australia and now it is one of the greenest, after Mars Australia signed a deal to offset 100 per cent of its power consumption. Mars Australia cannot power its operations directly off solar because they have six factories and two office complexes scattered all over the country. So they have signed a deal with the Kiamal solar farm in Victoria, where Mars Australia will pay them to offset their carbon emissions by matching it with green energy to supply to the grid. Mars Australia commercial manager Savannah Wallen said they knew they had a responsibility as a company to move towards more sustainable operations, and this option was the best way to achieve it.
