The import tariffs imposed by the nation’s 47th President through executive action, much to the chagrin of many North Americans, are expected to result in lower emissions in the air shared by Canada, Mexico, and the United States.
How, you ask?
Let me explain
American consumers will likely pay more for imports from Canada and Mexico, leading to a decrease in purchases of affected items. This may result in fewer cross-border shipments by truck, train, or plane, shifting the source of imported goods to other countries and potentially increasing emissions from aviation and sea transport globally.
In the U.S., changes in cargo transportation may not necessarily increase domestic emissions. Similar to the impact of congestion pricing in New York City, this shift could lead to lower emissions in certain areas while potentially increasing emissions in neighboring states due to changes in traffic patterns.
Furthermore, the tariffs may encourage American consumers to buy locally, reducing cross-border transportation and fuel consumption. This can result in lower emissions and less pollution in the atmosphere and respiratory systems.
Although there may be concerns about potential increases in domestic drilling, refining, and manufacturing activities leading to higher emissions, the overall impact of the tariffs on emissions remains to be seen.
Ultimately, the effects of these actions will become clearer over time.
