U.S. Automakers Have Been Undermining Climate Science Since the 1960s, Investigation Reveals

"Scientists at two of America's biggest automakers knew as early as the 1960s that car emissions caused climate change," reports Maxine Joselow, sharing the findings of a monthslong investigation by E&E News.

"The discoveries by General Motors and Ford Motor Co. preceded decades of political lobbying by the two car giants that undermined global attempts to reduce emissions while stalling U.S. efforts to make vehicles cleaner," according to Joselow.

In the present day, the transportation sector is the leading source of greenhouse gas emissions in the United States. Also, according to the article, both companies now have plans to reduce emissions from their cars.
