OPeN supports parliaments around the world to collaborate with civil society to become more transparent, accountable and participative, as well as to contribute to broader government-led openness initiatives. In this, OPeN members draw on an unrivalled background in relevant programming to advance the four pillars of parliamentary openness – Transparency and Access to Information, Ethics and Probity, Accountability, and Citizen Participation.  OPeN works by:

• Providing technical and process-related support for parliaments and civil society to co-create, deliver and oversee the implementation of open parliament initiatives, commitments and plans.
• Generating interest, awareness and political will for parliamentary openness, such as through knowledge building events and exchanges
• Developing tools and resources for parliaments and civil society, and for the broader Open Government Partnership (OGP) community, including step-by-step guidance and solutions to common challenges.
• Enabling peer-to-peer sharing of experiences and lessons, such as for the use of innovative information technology for transparency and citizen participation.
• Advancing the engagement of legislatures in broader OGP processes, to ensure parliaments contribute to designing, taking forward and monitoring government-led commitments. 
• Conducting research to identify and share lessons and good practice, and knowledge-gaps to inform future investigations.

In recent years, there has been growing recognition that legislatures can be strong drivers of openness reform and key allies to the open government agenda. Indeed, legislatures are currently the third-fastest growing area in OGP Action Plans across the world, and the second fastest in Asia and Europe. While OPeN’s remit is not limited to countries and parliaments operating in the framework of the OGP, our work ties in closely with the Partnership in view of the central role it plays in advancing open governance reforms worldwide.
