A new characteristic finite element scheme is presented for convection-diffusion problems. It is of second order accuracy in time increment, symmetric, and unconditionally stable. Optimal error estimates are proved in the framework of L-2-theory. Numerical results are presented for two examples, which show the advantage of the scheme.
