Lower traction power necessary, less local emissions (if not electric or hydrogen), less PM production, and if built correctly, lower noise. If built with green track, even lower noise emissions, and a measurable (as trivial as it might sound) heat island effect reduction due to increased vegatation evapotranspiration, as well as increased aesthetic.
If looking at it systemically, the "rail bias" which can be significant, also then reduces SOV trips thereby contributing to overall decreases to congestion, as well as the corresponding local emissions, noise, accident costs and parking spaces necessary.
I would be of the opinion that trams are generally undervalued, due to the fact that on a travel time savings metric, they don't generate much for perceived benefits.
