On the international scene, USA area has undertook the first experience about the program exchange of credits in water quality mode can-and-trade in 2009. Now 32 States have established “trading programs” and/or “state policies” on the matter and no. 2 “inter-state trading projects”.
Outside of the United States are currently reported N. 9 “trading programs”, of which no. 1 in Europe (the Netherlands) and no. 3 “Comparative International Studies.”
CESI sustains the possibility to define a national program for water quality credit trading – between companies within the same river basin district – as a support to the quantitative and quality objectives of water bodies provided for by the EU Directive 2000/60 (Water Framework Directive – WFD).
The companies in the program can buy or sell credits of water quality within the limits – the cap – defined by the Plan refers to the district area (cap-and-trade). Units of water quality can be exchanged at national level between districts more and less virtuous one.
Put a price on the shares of water quality, as experience taught in the trading of CO2, it could lead to a widespread commitment to the improvement of qualitative and quantitative characteristics of the resource and environmental systems connected to it.
It is therefore necessary to define a path for the implementation of the program:Identification of an entity in charge of the management of environmental creditsIdentification of a set of quality parameters of the systemDefinition of units of entry: the person in charge of the program shall specify for each parameter included in the project, an entry in line with the global annual quality objectives.
