-14 how to reduce the likelihood or risk of torture or ill-treatment that aim to support the State in the identification of forward-looking solutions and achieving change. As a result, NPMs can be a key player in upholding and harmonising EU standards on detention conditions. Project objectives To facilitate their work, this Project produced a series of Handbooks for NPMs. These Handbooks collect relevant international standards and provide guidance on monitoring detention conditions. They are intended as a practical tool for NPMs to get a better understanding on: • The thematic issues and risks for the prevention of torture and illtreatment connected to them • The existing international standards on selected thematic issues • How to apply these international standards in practice and monitor selected thematic issues Overall, the Project aims to support NPMs in putting forward recommendations on how to reduce the likelihood or risk of torture or ill-treatment and, ultimately, contribute to prison conditions in full compliance with fundamental rights in the EU.
