63. The mitigation actions in the energy sector focus mainly on improving energy efficiency and promoting use of renewable energy sources. Gabon reported the results of implementing the mitigation actions as estimated emission reductions. The Party estimates that its cumulative commitments in the energy sector will result in relative GHG emission reductions of more than 28,000 Gg CO eq, or 43 per cent, by 2050 compared with the 'business as usual' scenario on the basis of macroeconomic, social and infrastructure development assumptions. This estimated emission reduction is based on the anticipated results of seven main actions: developing and interconnecting transport networks (reduction of 4,600 Gg CO2 eq); implementing a zero gas flaring plan in the oil and gas industries (reduction of 4,000 Gg CO eq); improving energy efficiency in the transport subsector (reduction of 4,000 Gg CO eq); improving energy efficiency in households (reduction of 2,900 Gg CO eq); developing hydroelectricity (reduction of 2,300 Gg CO eq); substituting heavy fuel oil and diesel power plants with natural gas and natural gas power plants (reduction of 1,200 Gg CO eq); and introducing solar photovoltaic energy into the energy mix (reduction of 900 Gg CO eq).
