Transparency should be the hallmark international organizations, especially those funded by taxpayers. The United Nations Conference on Sustainable Development (Rio+20) was an enormous event that did not lead to substantial policy changes by member states. In addition to the conference, the United Nations sponsored several related reports and other events. The United Nations has not revealed the cost of the conference and these other activities, nor has it responded to numerous requests to do so.
In the current economic climate, funding for international organizations is scarce. To support the most effective use of this funding, the United Nations should give a full and transparent accounting of Rio+20. Without this accounting, it will be impossible to compare the benefits of Rio+20 to its costs.
