Incorporation of biofuels in diesel and gasoline. OBJECTIVE Reduce greenhouse gas emissions in the transportation sector through the incorporation of biofuels. Reduce import of fossil fuels. DESCRIPTION Incorporation of biofuels. Mixture of bioethanol in naphthas and mixture of biodiesel in diesel. IMPLEMENTED ACTIONS The incorporation of biofuels is aligned with the objectives of the country&#39;s 2005 - 2030 Energy Policy and the National Climate Change Policy, with the transport sector representing 56% of CO emissions, of the energy sector as a whole (BEN 2020 ). Law No. 18,195 on Agrofuels establishes the obligation to mix at least 5% biodiesel in diesel starting in 2012 and 5% bioethanol in gasoline (naphthas) starting in 2015. As mentioned in Section 3.1, in the 2021 Accountability Law, these percentages are modified, which will take effect as of January 1, 2022. Decree No. 523/008, regulating Law No. 18,195, contemplates aspects considered related to the authorization of production, the quality of agrofuels and the commercialization of biofuels. On the other hand, URSEA approved the Biodiesel and Fuel Alcohol Quality Control Regulation, which defines the responsibilities and procedures related to the quality control of these biofuels. Regarding technical regulations, Uruguay has a quality standard for Biodiesel, UNIT 1100:2014 Biodiesel (B100)-Fuel for mixing with petroleum middle distillates. This standard is established as mandatory in Law No. 18,195. There are two standards for ethanol fuel, which are established as mandatory in the regulatory decree of the law, UNIT 1122: 2009 Anhydrous ethanol fuel (AEAC): requirements and UNIT 1124: 2010 Hydrated ethyl alcohol fuel (AEHC). Requirements. Life cycle analyzes of biofuel production in Uruguay were carried out, from which it is possible to determine emission factors in the production of biofuels (CIEMAT 2015, 2017). Energy SECTOR - Transportation GOAL BY 2025 Incorporation of 5% bioethanol blend in gasoline and 5% biodiesel blend in diesel. INDICATOR -% of bioethanol mixed in gasoline. -% of biodiesel mixed in diesel. GAS CO METHODOLOGY The % of biodiesel is
