Bearing in mind the lack of LCA studies and the development of several hydroelectric projects in Ecuador, the purpose of this paper is to present a complete environmental performance of two hydropower schemes (dam and run-of-river) located in this country, through the life cycle assessment combined with reservoir GHG emissions approach. The run-of-river scheme had better environmental performance than the dam scheme. Very high emissions were found, being 547 Kg CO2-eq/MWh for dam scheme, which most of those emissions were originated in the reservoir, while the run-of-river scheme only score 2.6 Kg CO2-eq/MWh. However, comparing with fossil fuel power plants, hydropower dam case still has lower emissions in its entire life cycle. The paper remark that the majority of LCA studies which focus on dam hydropower scheme only consider the emissions of the construction, putting aside the loss of the ecosystem and the emissions caused by the impoundment. Moreover, the analysis also included the impact associated to water uses since reservoirs are usually devoted to several purposes (flood lamination, irrigation, ecological flow, power generation). 000070592 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000070592 590__ $$a4.9$$b2017 000070592 591__ $$aGREEN & SUSTAINABLE SCIENCE & TECHNOLOGY$$b7 / 33 = 0.212$$c2017$$dQ1$$eT1 000070592 591__ $$aENERGY & FUELS$$b20 / 97 = 0.206$$c2017$$dQ1$$eT1 000070592 592__ $$a1.847$$b2017 000070592 593__ $$aRenewable Energy, Sustainability and the Environment$$c2017$$dQ1 000070592 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000070592 700__ $$0(orcid)0000-0003-4408-6881$$aUche, Javier$$uUniversidad de Zaragoza 000070592 700__ $$0(orcid)0000-0003-1238-8746$$aMartínez-Gracia, Amaya$$uUniversidad de Zaragoza 000070592 7102_ $$15004$$2590$$aUniversidad de Zaragoza$$bDpto.
