There is a clear consensus on the current state of institutional deficiencies, but there are many ongoing heated debates on how to improve them. For example, some argue that a World Environment Organization is necessary to improve GEG's effectiveness, while others argue that it is better to cluster institutions according to different issue areas to generate synergistic effects among them. Several dimensions of regime effectiveness have to be taken into consideration for its definition: behavioral change, efficiency and equity, problem solving, goal attainment, as well as procedural, constitutive, and evaluative effectiveness. Although the most obvious effect of international environmental regimes is to solve the problem in question, there are only few cases that clearly show any improvement of the environment except for the ozone regime and the international regulation of oil pollution of the sea. The latter regime became very effective after changing the regulatory approach from the well-defined rules regarding the discharge of ballast from tankers to a system of equipment standards and port facilities.
