||While Taiwan has set the Intended Nationally Determined Contribution, as well as the national near-, medium-, and long-term greenhouse gas phase control targets in accord with the Paris Agreement, the specific greenhouse gas reduction program at the individual level is still missing. Hence this study attempted to explore three major categories of carbon reduction measures, including individual daily diet, green transportation, and energy use, followed by the quantification of the individual’s carbon footprint; after a consolidation of all these considerations, a personal carbon footprint action plan was proposed. In addition, an assumption that the whole national population of Taiwan adopts the individual carbon footprint action plan recommended in this study was made to examine whether its overall carbon reduction could achieve greenhouse gas periodic regulatory goal in Taiwan. It was found that at the level of personal diets, such as the low-carb diet approach, reduction of 1.18 kgCO2-eq per day in carbon emission can be achieved; in terms of personal green transportation, the maximum of daily carbon emissions can be reduced by 2 kgCO2-eq, depending on which vehicles are transferred to the public transportation system; for the aspect of personal energy consumption, if energy-saving and water-saving measures are taken, each person′s daily use of energy will reduce carbon emissionsby 1.14 kgCO2-eq.In other words, if the individual carbon footprint action plan recommended by this studyis adopted, the daily carbon footprint per person can be reduced by up to 4.32 kgCO2-eq. Assuming that the entire population adopts this individual carbon footprint action plan, Taiwan′s greenhouse gas phase control target can be achieved in both 2020 and 2025,70% of the greenhouse gas phase control targets for 2030 will be achieved, and 28% of the 2050 greenhouse gas phase control targets will be met. Given that this study only considered the carbon footprint of the personal diet, green transportation, and energy use, exclusive of other parts of the daily life such as the consumer and tourism behavior, if all these factors are taken into account, it can be expected that individual carbon emissions can be reduced further.However, how to achieve a proper balance between personal living quality and the sustainable environment is still a topic that needs to be explored and measured.|
