My first thought is that the cap isn't on real snug, and some fluid vented out the drain hole by the cap. But, I don't believe that would exit under the "left" rear tire.

Keep an eye on it to see if it recurs. If not, chalk it up to odd. Sometimes the A/C drains/vents and the water can get to other places on the ground. Green? That is odd.
