Immigration EIS

Welcome to the website for the Environmental Impact Statement (EIS) on United States Immigration Policy. This project aims to develop a thorough, objective analysis of the ecological impacts of U.S. immigration policy, so that informed policy decisions can be made in full knowledge of those impacts. EIS preparation was an interdisciplinary team effort, led by principal investigator Leon Kolankiewicz and coordinated by Progressives for Immigration Reform.  The Draft EIS was completed in the fall of 2015 and the Final EIS in the spring of 2016.

The main policy question evaluated in this EIS was the following:

  • At what level should Congress set annual immigration into the United States?
  • What are the comparative environmental consequences of alternative levels?

Further questions that bear on this issue include the following:

  • How would different immigration levels lead to different U.S. population sizes in 2050, 2100, and 2200?
  • How would different numbers of Americans change our cumulative environmental impacts, regarding biodiversity, wildlife habitat and farm land losses, water withdrawals from natural systems, energy consumption, and  national greenhouse gas emissions?
  • What total U.S. population is ecologically sustainable, over the long term?
  • What effect does U.S. immigration policy have on the environment and natural resources of other nations?

The EIS on United States Immigration Policy is a Programmatic EIS, meaning that it addresses broad issues and potential impacts in a general way.
