Our mission & goals

Share knowledge,
support and promote
open contracting

The C5 initiative aims to bring governments together to share knowledge and best practice, support each other, and promote open contracting on the global stage. This serves to improve government efficiency and ensure the huge sums of money spent on government procurement lead to high-quality citizen services. Through open contracting, the initiative seeks to create fairer and better competition in the market, to foster innovation, empower smaller businesses and bolster public integrity and transparency. The C5 governments will work together to undertake the actions committed to in the C5 Declaration. These are:

C5 Declaration


Implement the Open Contracting Data Standard (OCDS) to the fullest extent possible to create a timely, accessible public record for government, business and citizens on how public money is spent across the entire cycle of public contracting from planning to tender to award to implementation of contracts.


Foster innovation through supporting an ecosystem of open source, re-usable and shareable tools to improve communication, analysis, data quality and automation of public contracting information.


Contribute to the further development and use of the ODCS through case studies and analysis of user needs, encouraging extensions and joined up data including with corporate registries, joining and encouraging its user community and contributing to its further adoption.


Document the lessons learned, and measure the real-world benefits for government, business, and citizens from our adoption and implementation of open contracting for sharing, learning, and improvement. Focus collectively on the key user needs and capacities for government contracting information – such as improving value for money, creating a fair and level playing field for businesses, tracking and improving service delivery and upholding public integrity and deterring fraud and corruption – to shape, share and adopt a common methodology for building capacities and measuring impacts from our interventions to refine and share such methodologies globally.


Consider, refine and adopt best practices to engage business and civic organisations at appropriate points along the entire chain of procurement and to share our approaches, strategies and lessons from our efforts to make public contracting more engaging and responsive.


Engage other countries on our objectives, including through the Open Data Charter, Open Government Partnership, the OECD, the G20, our multilateral development banks and other relevant international or sector specific initiatives such as the Construction Sector Transparency Initiative, the Extractive Industry Transparency Initiative and encourage them to embrace and implement open contracting principles.


Engage our international development partners and institutions in furthering these objectives nationally and internationally including in priority sectors such as infrastructure and healthcare.
