The estimates for the Energy Sector were affected by increased imports of petroleum fuels since 2012. There was a general increase in the emissions of CO2, CH4, and NO over the period across all the subsectors except for the transport sub-sector showing a slight decrease from the 2015 level. The electricity generation sub-sector saw a slightly increase in the use of petroleum fuels. The use of renewable energy sources combined with the importation of electricity from Mexico helped to mitigate GHG emissions for electricity generation. The largest increase in use of petroleum fuel during this study period was in the transport sub-sector which contributed to increasing the greenhouse gas emissions. The increase in petroleum fuel consumption was in three sub-sectors; land, sea and air, and this sub-sector contributed to the greater proportion of the sector emissions. However, there was a decrease in petroleum products consumption and emissions for the transport sub-sector in 2017. Fuel consumption for national aviation
