I think you are going to see catalytic converters to meet the new

Might be a fire hazard on lawn mowers. Those catalytic converters are
quite hot. Still, lawn mowers are quite dirty by today's standards.

"The 20,000,000 small engines sold in the U.S. each year contribute about
one tenth of the total U.S. mobile source hydrocarbon emissions, and are
the largest single contributor to these non-road emissions."
