In addition a general emissions reduction by improvements in energy efficiency economy wide. The target is for the renewable energy share in electricity generation to approach 100% by 2030 from around 60% in 2013. In addition an indicative reduction of 10% CO2 emissions for energy efficiency improvements economy wide will be sought. These measures will reduce CO2 emissions in the energy sector by around 30% from BAU by 2030. Reference year or period 2013 Estimated, quantified emissions impact A business as usual (BAU) scenario for total fossil fuel increases for energy production for extrapolated population and economic growth would give total CO2 emissions in 2030 from the energy sector of around 2500 Gg with an electricity sector CO2 emission level of around 500 Gg.
