The US environmental protection agency some times called the ethanol production agency declared war on nitrogen oxide emissions in the late 1960s or early 1970s because a hand full of places, probably around 0.1% of the lower 48 land area had smog problems because they bet on infinite exponential growth.
And that killed the diesel small vehicle market here in the US about the time it started and killed off lean lean burn gasoline engines by the 1990s.
