Abstract

This article clarifies the potential environmental impacts of more or less expansive EU immigration policies. First, we project the demographic impacts of different immigration policy scenarios on future population numbers, finding that relatively small annual differences in immigration levels lead to large differences in future population numbers, both nationally and region-wide. Second, we analyze the potential impacts of future population numbers on two key environmental goals: reducing the EU’s greenhouse gas emissions and preserving its biodiversity. We find that in both cases, smaller populations make success in these endeavors more likely – though only in conjunction with comprehensive policy changes which lock in the environmental benefits of smaller populations. Reducing immigration in order to stabilize or reduce populations thus can help EU nations create ecologically sustainable societies, while increasing immigration will tend to move them further away from this goal.
欧盟移民政策对环境的潜在影响:未来人口数量、温室气体排放和生物多样性保护
本文阐明了或多或少宽松的欧盟移民政策对环境的潜在影响。首先,我们预测了不同移民政策情景对未来人口数量的人口影响,发现移民水平的相对较小的年度差异导致了国家和地区范围内未来人口数量的巨大差异。其次,我们分析了未来人口数量对两个关键环境目标的潜在影响:减少欧盟温室气体排放和保护其生物多样性。我们发现,在这两种情况下,较小的人口更有可能在这些努力中取得成功——尽管只有与锁定较小人口的环境效益的全面政策变化相结合。为了稳定或减少人口而减少移民可以帮助欧盟国家创建生态可持续的社会,而增加移民往往会使他们远离这一目标。
