Popis: The Galapagos archipelago as symbol for the theory of evolution is especially vulnerable to all negative effects of fossil fuels [Gruber, 2014]. Situated in the Pacific some 1,000 km from coast of Ecuador, the Galapagos Islands have been inscribed in the UNESCO world heritage since 1978. Later on, in 2007 UNESCO put the Galápagos Islands on their List of World Heritage in Danger [ISES, 2011]. The Zero fossil fuels Initiative, on the Galapagos Islands, aims to replace the diesel used for power generation in Floreana Island, by Straight Jatropha Oil (SJO) growing in the province of Manabi [GIZ, 2014]. The generation of this electricity contributes to the mitigation of climate change, rural development and conserving land for use different to energy, leading to positive impacts on environmental, economic and social aspects [GIZ, 2014]. A Life Cycle Assessment (LCA) was conducted for blend Diesel-SJO based electricity generation. Furthermore, a comparative analysis was generated for three scenarios: blend system (D80-SJ020) SJO system (SJO100) and Diesel system (D100). Finally sustainability assessment of electricity production system, was developed. From an environmental point of view, production of a 1MWh generated whit the D80-SJO20 blend, shows savings for climate change and energy fossil consumption of 122,83 kg CO2eq (13,2%) and 1,5 GJ (12,0%) respectively, regarding to Diesel system (D100). For both categories, electricity generation phase, it is the major contributor with 97,35% in the case of climate change and 96,11% for energy consumption.
