Energy Emissions

The emissions of the main considered gases are presented in Table 2.1. Besides the results of the program, data relative to population and Gross Domestic Product (GDP) were also included in the Table.

In Table 2.1 are presented emissions of all gases considered in the program as well as data for carbon dioxide without biomass emission (CO2*), according to IPCC recommendation, and data with biomass emission (CO2). It is also presented data relative to CO that could be subject to the same restriction, since in a few years CO is converted to CO2 and therefore its effect when originated from biomass is nullified (absorbed=emitted). For the other carbon compounds (CH4 and NMVOCs) the dynamics is more complex, even though, in the long term, the resulting CO2 is null when originated from renewed biomass. As a global measure of these emissions one can use the total carbon. In the table are presented the carbon emissions from renewable fuels and the total emission.

In Table 2.2 are given the growth rate values of the parameters presented in the previous table in the considered years.
