>  From Roytenberg-Ševera, we know that Poisson manifolds are in one-to- 
> one correspondence with symplectic NQ-manifolds of degree one. Cattaneo- 
> Zambon further extended this relation to the level of reduction with 
> their graded geometric approach to Poisson reduction. Based on these 
> ideas, we explain how homotopy Poisson structures may arise as 
> homological models for Poisson reduced spaces obtained from more general 
> reduction setups. Our results extend the classical homological 
> formulation of hamiltonian reduction of symplectic and Poisson manifolds 
> due to Kostant-Sternberg and Stasheff.
