A 2021 report from the Transnational Institute calculated that seven countries (the United States, Germany, Japan, the United Kingdom, Canada, France, and Australia)—together responsible for 48 percent of the world’s historic greenhouse gas emissions—“collectively spent at least twice as much on border and immigration enforcement (more than $33.1 billion) as on climate finance ($14.4 billion) between 2013 and 2018.”
