  We present a manifestly local, diffeomorphism invariant and locally Poincare
invariant formulation of vacuum energy sequestering. In this theory, quantum
vacuum energy generated by matter loops is cancelled by auxiliary fields. The
auxiliary fields decouple from gravity almost completely. Their only residual
effect is an a priori arbitrary, finite contribution to the curvature of the
background geometry, which is radiatively stable. Its value is to be determined
by a measurement, like the finite part of any radiatively stable UV-sensitive
quantity in quantum field theory.
