A New Approach to Justice and Accountability
The Atrocity Crimes Advisory Group (ACA) for Ukraine is an initiative established by the European Union, the United States, and the United Kingdom in partnership with the Government of Ukraine to support Ukraine’s efforts to ensure justice and accountability for atrocity crimes committed in the context of Russia’s full-scale invasion.
As a new approach to advancing justice in a conflict setting, ACA’s innovative model enhances national authorities’ ability to bring justice for victims of atrocity crimes through domestic mechanisms and in coordination with international expertise and bodies.
Coordinated, Multilateral Support

The European Union, the United States, and the United Kingdom launched the ACA in May 2022, announcing their collective efforts via a joint ministerial statement. The ACA provides coordinated, timely, multidisciplinary expert assistance to the Office of the Prosecutor General (OPG) of Ukraine, which has the primary authority and responsibility for prosecuting atrocity crimes that took place on its territory.
The ACA is an essential element of the United States’ commitment that those responsible for such crimes will be held to account.

The atrocities we’ve witnessed in Ukraine since Russia’s illegal invasion are sickening. Those responsible must be held to account.

It is critical to ensure that all those responsible for the terrible atrocities committed during the unprovoked Russian military aggression in Ukraine are brought to justice. There can be no impunity for war crimes.
