The Research Project on Shared Responsibility in International Law (SHARES) is pleased to announce the official launch of the SHARES website: www.sharesproject.nl. The website includes a detailed description of the SHARES project and its project members. The website also features news, events, publications, blog posts and resources on shared responsibility in international law. The ambition of the SHARES project is to examine an unexplored and largely unrecognized problem: the allocation of international responsibilities among multiple states and other actors. It seeks to uncover the nature and extent of the problem of sharing responsibility in an increasingly interdependent and heterogeneous international legal order. SHARES will therefore offer new concepts, principles and perspectives for understanding how the international legal order may deal with shared responsibilities. The SHARES project is a research project of the Amsterdam Center for International Law, led by Professor André Nollkaemper, and funded by the European Research Council.
