The Marginal Abatement Cost Curves(MACC) analysis in the Romania Green Growth study presents across-sectoral outlook of the benefits and costs of thegreen technologies and abatement measures recommended in thesectoral modeling and analysis for the time period2015-2050. MACC are a commonly used tool in evaluatingemissions reduction technologies and a most efficientcommunication instrument for discussions of the abatementpolicies. Romania’s MACC is a combination of sectoralcurves, each of which was built using the most appropriateapproach for each sector. Global and local data sources wereuse in the MACC analysis. The findings are as follows: (i)sector analysis conducted for the Romania Green GrowthAssessment resulted in a selection of a list of measuresthat constitute a green package in each sector of energyefficiency, powersupply, forestry, agriculture,andtransport; (ii) a review by sector shows that energyefficiency measures are most beneficial, they have highabatement potential and mostly negative cost, whileelectricity supply interventions produce most of theabatement; (iii) agriculture and forestry measures are costefficient and (iv) in transport, attacking emissions andgenerating local co-benefits justifies the high cost of theinterventions and motivates support for improved transportpolicies. The conclusions and recommendations are asfollows: (a) The MACC work derives from the analysis andmodeling of all the relevant sectors in the Assessment; (b)when the MACC data from all sectors is modeled in one chart,it creates a clear and simple picture that compares greenmeasures by costs and benefits across sectors;and (c) theRomania MACC can increase the quality of decisions regardingprioritizing and scheduling the proposed abatement measures.
