Not seen the clip, does it specify which emissions they were talking about?
The pollutants counted in the seventies might well have been lead, unburned hydrocarbons and Carbon Monoxide? IIRC diesels burn fuel more efficiently. The word stoichiometric is ringing a bell but I cannot remember why, nor have I the time now to look into it.
Don't think CO2 was seen as a problem then. Not sure about SO and NOx either - when did acid rain become a thing?
