2.  After coming into effect of the Kyoto Protocol it has become more and more evident the inadequacy of the measures adopted by the Italian governments in order to respect the goals that, as a Country, we have obliged ourselves to reach.  In order to do some clarity, we will determine in an independent way how much CO 2 is emitted for each kWh of electric energy produced with the traditional thermoelectric plants; we will do it by utilizing official data, widely available and with a minimum of interpretation.  In particular, we will avail of the Specific Emission Coefficients indicated in the National Plan of Assignment (the document prepared by the Italian government in order to comply with the Directive 2003/87/CE of the European Union), e of the Statistical data about electric Energy in Italy 2003 published by GRTN.

3. The adopted methodology is very simple and thus repeatable:  First of all we have identified the quantity of CO 2 emitted for every kWh produced by means of the various types of fuel utilized in the production plants, and the quantity of energy produced with them.

5. The level of emission varies with the plant typology. The average has been computed utilizing for each typology the indicated number of operation hours (h*k,2005)

8. Dividing this quantity by the number of kWh produced we get the per-unit emissions, grams of carbon dioxide introduced in the atmosphere for every kWh produced in Italy by the thermoelectric plants. To complete the process, we need to introduce two corrections:  not all the produced electric energy goes into the network: an important part (more than 5,5%) is in fact utilized by the production plants themselves – the so-called self- consumptions – to allow their operation;  6,5% of the energy given to the network doesn’t arrive to consumers: these are the losses in the transmission and in the distribution of the energy. We omit to consider the energy utilized for the so-called pumping, that we assimilate to a smaller production of hydroelectric energy.
