Abstract

Carbon footprinting is currently the most widely used cliche for greenhouse gas ghgaccounting. Thus phenomenal growth of CFP claims on goods materials products or services is its linkage to climate change mitigation. Reducing ghg through better energy management of goods has expanded the importance of energy efficiency EE to beyond that of energy conservation. EE emphasizes reduced energy consumption such as electricity and fuel usage during production and utilisation of goods. Although there are different tools and approaches to calculate CFPs most of them include to various degrees the life cycle concept or life cycle assessment LCA technique. Hence reduced electric power consumption for work done is tracked back to the power plants where the fuel mix required to generate electricity produces a CFP that will eventually be borne by all goods requiring electricity for its operation. The paper will illustrate the contribution of ghg profile of electricity to the CFP associated with the performance or function of a product using the LCA approach. The example given was adapted from the APEC TILF Project of a common rice cooker used to provide cooked rice for 6 persons over 8 years. The electricity consumption in the manufacturing of the rice cooker was extracted directly from the case study at 1.10 kWh per rice cooker. The use phase reported in the study was modified for Malaysia's use pattern and totalled 559kWh over the 8 years lifetime. The ghg profile of electricity produced in Malaysia was calculated as 0.69kWh Co2eq/kWh based on the fuel mix for power generation in 2007. Using these values it is estimated the CFP for providing cooked rice to 6 persons for 8 years using a electric rice cooker was 397 kg CO2eq/rice cooker. The rice cooker example shows a direct relationship between EE and CFP.
