As seen in Figure Ex-2, the proportion of GHG emissions in the energy sector accounted for 71.21% of the national emissions in 2000, and increased by 74.35% by 2013. On the other hand, and over the same period, emissions in the agriculture sector decreased from 18.54% in 2000 to 15.98% in 2013. In the agriculture sector, total GHG emissions in 2013 were 50,919.34 GgCOeq. In the industrial processes sector, the proportion of GHG emissions remained constant. In 2013, the GHG emissions in the industrial processes sector were estimated to be 18,976.79 GgCOeq. In Land Use, Land-use Change, and Forestry (LULUCF), there was a trend of increased net removal. Since 2000, LULUCF activities contributed to the net removal from the atmosphere. In 2005, when rubber plantations were included in the calculation, there was a tremendous increase of CO removal.
