alt Hacker NewsPerhaps this is naive, but I would imagine that farm equipment is a rounding error in terms of global emissions. Compare the number of tractors to the number of trucks...
I would have expected policy to be pragmatic here, with (relatively) relaxed emissions requirements, since an affordable and reliable food supply is in the national interest? Sounds like that's not the case

Compare the number of tractors to the number of gas-powered lawnmowers. Which do you think gets better emissions?

Emissions regimes are complicated, but US tractors fall into the much less restrictive off-road category. As a result, they're a disproportionately significant contributor to things like NOx. A long time ago the off-road category was >20%, and I'm sure that percentage has only grown as regulations have forced emissions reductions in onroad vehicles.
