For the most effective science, gravitational wave astrophysics must be pursued in an international context. However, new and existing gravitational wave projects are generally pursued by national or regional collaborations. To help the gravitational wave community and its funding agencies appreciate these larger issues, GWIC issues statements on its assessment of the value of new or continuing activities. Such questions may be brought to GWIC by any research group or collaboration -- GWIC will consider the arguments in favor of the proposed course of action, and discuss the relevant issues, paying particular attention to potential impact on the international efforts.

If GWIC reaches a strong consensus, it will issue a formal Statement or letter laying out its view. Such Statements carry the full backing of the leaders of the projects represented on GWIC.
