The Open Government Partnership (OGP) has been hugely successful in raising the importance
of transparency and accountability in public service delivery, including how it contributes to more
accessible and affordable infrastructure for citizens. This Guidance Note outlines how CoST can assist members of the OGP to meet their commitments to improving transparency and accountability in public infrastructure. It identifies how the CoST approach to transparency and accountability aligns with the OGP principles and provides model commitments for inclusion in an OGP Action Plan.
