Abstract


Non-renewable resources are becoming scarce and current Global Warming Potential (GWP) values are rising. In an effort to promote a successful shift towards a “greener’ planet, governments worldwide are developing policies (such as Carbon taxation), which encourage businesses to contribute to the effort.  This study analysed the Product Carbon Footprint of the packaging process for 300ml Glass and 500 ml PET containers for a South African soft drink manufacturing business. Review of academic literature revealed that no similar research had been conducted in South Africa. The Green House Gas protocol was used as the basis for the research method. It was found that the 500 ml PET packaging process draws 100% of its Cumulative Energy Demand from purchased electricity (generated by burning coal) and has a global warming potential per hectolitre which is 4.5 times less than that for 300ml Glass - which has 71 % of its emissions resulting directly from coal fired boilers on site. A sensitivity analysis revealed that packaging in larger containers results in a significant global warming potential reductions per volume for both Glass and PET containers.
