I assume the negative pollution number means it sucks pollution up? Makes sense, it uses CO2 from the environment around it to grow trees. No complaints.

But in that case, it's weird that it sucks up less pollution when fueled by crushed coal, no? I mean, the math checks out (75% of -0.5 is -0.375), but I thought the point of crushed coal was to reduce pollution - so maybe it shouldn't reduce the efficiency of pollution-sucking machines? Maybe a bug? Maybe I'm stupid?
