Global Resource Agency
As proposed by Earth Rights:
"Urgently needed is the establishment of a Global Resource Agency to collect user fees for transnational commons. This would include parking charges for satellites placed in geostationary orbits, royalties on minerals mined or fish caught in international waters and use of the electromagnetic spectrum.
Other significant global revenue sources are taxes or fees based on the polluter-pay principle, such as international flights or aviation fuel, international shipping, or dumping at sea. A tax on currency speculation has also been proposed. To be considered is whether international arms trading should be heavily taxed or completely abolished.
The Global Resource Agency could also be responsible for monitoring the global commons (e.g., the ozone shield, forest reserves, fish, biodiversity), determining rules for access, issuing permits and collecting resource revenues. Such a body could also assume substantial authority for levying fines and penalties for the abuse of common heritage resources.
Revenues raised from access fees for the use of global commons could fund sustainable development programs, environmental restoration, peacekeeping activities, or low interest loans for poverty eradication. Funds are also needed on the global level to finance justice institutions such as the World Court and the International Criminal Court and to facilitate policy convergence in areas such as trade, currency exchange, and human rights. The Global Resource Agency could be mandated to distribute resource revenues equitably throughout the world as calculated by formulas based on population, development criteria and currency purchasing capacity."
