The impact of human civilization on the environment is now obvious. With the rapidly growing human population, the problem of human consumption becomes more and more urgent. It is therefore necessary to try to change the patterns of human life and find a more sustainable way of living. To achieve the goal of sustainable society efficiently, it is crucial to identify hot spots for possible impact reduction. Even though several tools now exist, such as footprint calculators, they usually have a narrow perspective, calculating impact only on a single environmental problem. In this study, the Life Cycle Assessment (LCA) method was employed, to measure the environmental impact of human consumption across the entire life-cycle as well as a wide range of impact categories. The use of LCA to identify the major problems of personal consumption is presented in a case study of an average inhabitant of the Czech Republic. Data of average personal consumption were collected and an LCA model was created in GaBi 8 software. Characterization results, obtained using ReCiPe 2016 (E) methodology, show the environmentally dominant segments of consumption which are: household energy consumption – where the dominant process is heating; and food consumption – where the dominant processes are meat and dairy production. This study provides a thorough impact analysis and identifies the hots spots, where actions should be taken. The results provide the necessary basic data for policy-makers, so that steps to reduce individual personal environmental impact can be taken.

从生命周期角度看个人消费对环境的影响-捷克的一个案例研究。

现在人类文明对环境的影响是显而易见的。随着人口的快速增长,人类消费问题变得越来越紧迫。因此,有必要尝试改变人类的生活方式,找到一种更可持续的生活方式。为了有效地实现可持续社会的目标,至关重要的是确定热点,以减少可能的影响。尽管现在存在几种工具,例如足迹计算器,但它们通常具有狭窄的视角,仅计算对单个环境问题的影响。在这项研究中,使用了生命周期评估(LCA)方法来衡量人类消费在整个生命周期以及各种影响类别中对环境的影响。在捷克共和国一个普通居民的案例研究中,介绍了使用LCA来识别个人消费的主要问题。收集了平均个人消费数据,并在GaBi 8软件中创建了LCA模型。使用ReCiPe 2016(E)方法获得的表征结果显示,环境消耗的主要部分为:家庭能源消耗–主要过程为供暖;和食品消费-主要过程是肉类和奶制品生产。这项研究提供了全面的影响分析,并确定了应该采取行动的热点。结果为决策者提供了必要的基本数据,以便可以采取措施减少个人的个人环境影响。收集了平均个人消费数据,并在GaBi 8软件中创建了LCA模型。使用ReCiPe 2016(E)方法获得的表征结果显示,环境消耗的主要部分为:家庭能源消耗–主要过程为供暖;和食品消费-主要过程是肉类和奶制品生产。这项研究提供了全面的影响分析,并确定了应该采取行动的热点。结果为决策者提供了必要的基本数据,以便可以采取措施减少个人的个人环境影响。收集了平均个人消费数据,并在GaBi 8软件中创建了LCA模型。使用ReCiPe 2016(E)方法获得的表征结果显示,环境消耗的主要部分为:家庭能源消耗–主要过程为供暖;和食品消费-主要过程是肉类和奶制品生产。这项研究提供了全面的影响分析,并确定了应该采取行动的热点。结果为决策者提供了必要的基本数据,以便可以采取措施减少个人的个人环境影响。显示消费的环境主要部分:家庭能源消耗–主要过程是供暖;和食品消费-主要过程是肉类和奶制品生产。这项研究提供了全面的影响分析,并确定了应该采取行动的热点。结果为决策者提供了必要的基本数据,以便可以采取措施减少个人的个人环境影响。显示消费的环境主要部分:家庭能源消耗–主要过程是供暖;和食品消费-主要过程是肉类和奶制品生产。这项研究提供了全面的影响分析,并确定了应该采取行动的热点。结果为决策者提供了必要的基本数据,以便可以采取措施减少个人的个人环境影响。
