Let G be a real connected Lie group with polynomial volume growth, endowed with its Haar measure dx. Given a C 2 positive function M on G, we give a sufficient condition for an L 2 Poincaré inequality with respect to the measure M (x)dx to hold on G. We then establish a non-local Poincaré inequality on G with respect to M (x)dx.
