Immigration to the United States and World-Wide Greenhouse Gas Emissions, by Steven Camarota, Leon Kolankiewicz, August 2008

• “The findings of this study indicate that future levels of immigration will have a significant impact on efforts to reduce global CO2 emissions. Immigration to the United States significantly increases world-wide CO2 emissions because it transfers population from lower-polluting parts of the world to the United States, which is a higher-polluting country. On average immigrants increase their emissions four-fold by coming to America.”
