Shared Responsibility in International Law

SHARES (2010-2015)

The SHARES Project examined an unexplored and largely unrecognised problem: the allocation of international responsibility among multiple states and other actors. It uncovered the nature and extent of the problem of sharing responsibility in an increasingly interdependent and heterogeneous international legal order.

The Project produced output, offering new concepts, principles and perspectives for understanding how the international legal order may deal with shared responsibility. SHARES was funded by a European Research Council Advanced Grant of 2.1 million euro, obtained in 2010 by Professor André Nollkaemper. The Project ran until the end of 2015.
