Abstract : Latin America presents important energy resources and a relatively low level of CO 2 emissions. Energy needs increase and are expected to increase more and more with the objective of development and of energy access. Moreover, Latin America is already impacted by climate change with, for example, first snow, inundation, etc. So to evolve his development in sustainable manner, low carbon strategy has to be developed. This paper focuses on long term analysis of energy climate issues in Latin America and particularly studies the impact of climate policy on its energy system. Solutions to tend toward a decarbonized system are analyzed and a focus is made on Biomass with carbon capture and storage (BECCS). Notably, an interesting result is the fact that, while the carbon capture and storage option is favored in case of bioplants development, appearing as a first climate-protect option, this is not the case with fossil power plants, and renewables development is preferred, even when BECCS is " excluded " .
