Furthermore, national GHG emission projections show total emissions increasing by 4 to 8% by 2020 (excluding LULUCF) due to increased emissions from energy production, industrial activities and transport (APA, 2010). Energy transformation and transport were the major sources of CO2 emissions from fuel combustion, followed by the industrial sector (Figure 5.2). Energy industries were also responsible for about half the emissions of sulphur oxides (SOx) and 18% of those of nitrogen oxides (NCy on average during the same period. Transport remains the major source of NOx emissions (Table 3.1).
