我们专注于三个环境影响，特别是受人口年龄结构的影响，交通和住宅能源和电力消费的碳排放量，以及发达国家的总碳排放量，并作为我们的出发点，人口，富裕和技术（STIRPAT）框架的回归随机影响。我们的贡献之一是将人口进一步细分为三个特别关键的年龄组：20-34岁、35-49岁和50-64岁，这样做表明，人口对环境的影响在不同年龄组之间有很大差异，年龄较大的年龄组（通常与较大的家庭有关）实际上产生了负面影响。此外，对于我们分析的不同环境影响，这些特定年龄的人口影响是不同的（绝对和相对）。此外，我们发现，城市化，在发达国家，最好的措施，进入一个国家的电网，因此，是积极相关的能源消费在住宅部门。最后，我们提出了一些建模和方法的改进STIRPAT框架。
We focus on three environmental impacts particularly influenced by population age-structure-carbon emissions from transport and residential energy and electricity consumption-as well as aggregate carbon emissions for a panel of developed countries, and take as our starting point the Stochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT) framework. Among our contributions is to further disaggregate population into three particularly key age groups: 20-34, 35-49, and 50-64, and by doing so demonstrate that population's environmental impact differs considerably across age groups, with the older age groups (ones typically associated with larger households) actually exerting a negative influence. Furthermore, those age-specific population influences are different (in absolute and relative terms) for the different environmental impacts we analyze. Also, we find that urbanization, in developed countries, best measures access to a country's power grid, and thus, is positively associated with energy consumption in the residential sector. Finally, we suggest some modeling and methodological improvements to the STIRPAT framework.
