These directives suggest to accept only the contributions to the radiation effect of the direct greenhouse gases, carbon dioxide, methane and nitrous dioxide, by using the following global warming potentials: 21 for methane and 310 for nitrous dioxide, values corresponding to a 100-year period.

The inventory results indicate to Morocco’s very low contribution to the greenhouse effect increase, in comparison to the industrialized countries. This reflects low person consumption of energy: 0.33 tonne equivalent petrole per inhabitant (without biomass) and 0.51 tonne equivalent petrole per inhabitant (with biomass), for year 1994.

Net Greenhouse Gas emissions of anthropogenic origin have reached, in 1994, the following figures:

47917 kilotons equivalent Carbon dioxide (E-Carbon dioxide), which is 1.84 ton E-carbon dioxide per person, of which 1.22 ton of carbon dioxide.

The quantity of produced carbon dioxide Carbon dioxide (31.908 kt) is larger that that of methane (349 kt) and nitrous oxide N2O (28kt).

The main source of carbon dioxide is the burning of fossilized energies fuels (25.206 kt, or 68 %), followed by firewood energy (8.592 kt, or 23%) then by cement production (3.158 kt, or 91%).

From the net Carbon dioxide emissions, we exclude the carbon dioxide absorbed during the growth of forest trees, the growth of orchard trees and afforestation. The absorbed amount reaches 5.090 kilotons. In this was we get net emissions of Carbon dioxide of 31,908 kilotons.

Methane emissions come essentially from agriculture (55%) through enteric fermentation and manure and energy (18%). Those of nitrous dioxide result from agricultural soils and manure.

The analysis of net emissions per source shows the majority of the energy module (with 26,839 kt of equivalent carbon-dioxide, or 56% of the total), followed by that of agriculture, which is responsible for 25% of the total of Greenhouse Gas net emissions.

If we consider the gross amounts of emissions (53,007 kt equivalent-carbon dioxide), the weight to be attributed to modules changes. The Forest module increases from 7% to 16% of the total of equivalent carbon dioxide emissions, while that of Energy decreases from 56% to 51%. Amongst the other Greenhouse Gases, carbon monoxide (CO) comes immediately after Carbon dioxide, with 1.1 million tons released.
