We apply the local projection stabilization to finite element discretizations of scalar convection-diffusion-reaction equations with mixed boundary conditions. We derive general error estimates and discuss the choice of the stabilization parameter. Numerical results illustrate some drawbacks of the local projection stabilization in comparison to the SUPG method.
