Under the trend that product carbon footprint calculation is increasingly required, product carbon disclosure has become an important measure for green product marketing. In this project, we will not only develop an interaction platform for data quality system, but also create Apps for iOS. Besides, updating application programming interface such as Apps for the Android platform and web-based carbon footprint calculation tool is also an important task to strengthen the operation function of carbon footprint calculation service platform. In 2012, the official carbon footprint database has already developed by Taiwan EAP in order to simplify data acquirement process and assist Taiwan industries effectively respond relevant and emerging CFP tasks. Hence, the main task of extending the official carbon footprint database should aim at (1) setting up 50 sets of carbon footprint emission factors, (2) creating environmental product declaration and product category rule for paper products, and (3) reviewing the carbon footprint emission factors providing by other government departments or private enterprises (4) assisting Taiwan EPA to update and publish carbon footprint emission factors in the website of Taiwan EPA. In addition, the international cooperation is also established by delivering the international carbon labeling mutual recognition feasibility study to Carbon Trust and providing more than 5 sets of data which are reviewed and published in the website of Taiwan EPA to international database to extend the utilization and application of our official database.
