In this paper we use a potential-theoretic approach to establish various representation theorems and Poisson-Jensen-type formulas for subharmonic functions in sub-Riemannian settings. We also characterize the Radon measures in \begin{document}$ \mathbb{R}^N $\end{document} which are the Riesz-measures of bounded-above subharmonic functions in the whole space \begin{document}$ \mathbb{R}^N $\end{document} .
