Possible energy futures for Brazil and Latin America in conservative and stringent mitigation pathways up to 2050

摘要: Abstract Latin America has a unique position to address climate change impacts due its many mitigation opportunities and growing economy. This paper applied two global one regional integrated assessment models assess the energy emissions trends in Brazil rest of American region up 2050 based on set scenarios consistent with current 2 °C target. The show that achieve this target, deep CO 2 emission reductions are needed. power sector offers greatest opportunities. implementation CCS, combination fossil fuels bioenergy, hydro, biomass wind identified study as most promising low-carbon options for region. realistic these will depend, however, their capability overcome present technical, economic, environmental social challenges. Besides, an appropriate policy framework stimulate transformation system is also important. first country adopt national voluntary goal by law. However, effectiveness now becomes difficult vague targets established.
