Abstract:
This study was to develop the software for calculating carbon footprint of bottled drinking water. The evaluation was based on primary data gained from the factory of bottled drinking water and those derived from secondary information and research document of Franklin Associates. The software has been developed using Joomla software, HTML language, and PHP language. The software is divided into 2 parts according to its use, i.e. 1) design part: providing information of the carbon footprint and bottled drinking water and 2) analysis part: calculating the carbon footprint throughout life cycle of bottled drinking water. The results have shown that this software assembles, those data required but separately found, and systematic organizes such records. By contrast to manual calculation, the software yields much more prompt and accuracy data. Moreover, contemporary data base can be further included. Based on a dozen of 600 ml bottled drinking water, 1.2355 kg of carbon footprint is generated by the packaging process means, i.e. 44.94 % of the emission throughout its life cycle. The following is the transportation and the waste management in which release 1.0559 and 0.4303 kg of carbon footprint. Such figures correspond to 38.40% and 15.65%, respectively. The quantity of carbon footprint of the bottled drinking water is therefore, 2.75 kg carbon dioxide equivalent per dozen of the bottled drinking water.
