The total GHG emission increased 37% from the 1999 inventory, which was the most recent previous inventory. This increase in emissions was consistent with a population increase of 20% and the gross domestic product (GDP) of 50%. The IPPU sector increased GHG emissions by over 200 %, possibly as a result of the inclusion of the Iron Production category, which was not included in the 1999 inventory. The Energy sector increased GHG emissions by 42%, mainly due to higher emissions from the Transport subsector and an increase in fugitive methane emissions during oil and gas production. The Agriculture sub-sector decreased GHG emissions by 40%, which was not consistent with the increase in the area of agricultural land and the increase of production in relation to the year 1999, the reason of this decrease is probably due to methodological differences between the estimates for the year 1999 and 2010. The Forestry and Other Land Use sub-sector decreased its emission by 9%, mainly due to the duplication of the net absorption of the subsector in forest lands. The Waste sector did not experience a statistically significant change.
