The 2020 Aid Transparency Index reveals an improvement in overall transparency among the world’s major aid agencies, but there remains a gulf in the performance of the two UK donors included in the ranking. Released today by Publish What You Fund, the Index is the only independent measure of aid transparency among the world’s major aid donors. The research, undertaken before last week’s announcement of a merger, shows that while DFID remained in the ‘very good’ category as a global leader in aid transparency, the FCO ranked 38th out of 47 donors and failed to publish adequate information on the performance of its aid projects. As the shrinking UK economy puts aid under increasing financial pressure and resources are redirected to respond to the COVID-19 emergency, the Index results provide a timely reminder that we need to know that our aid is being spent in the most effective way to achieve the greatest impact.
