Modernization and energy efficiency actions in the Collective Transportation System Project title Modernization and energy efficiency actions in the Collective Transportation System (STC). Collective Transportation System, Metro. Responsible institution Through the modernization and maintenance of lighting fixtures, electromechanical stairs and trains, the aim is to reduce the Metro&#39;s electricity consumption and, consequently, its contribution to atmospheric emissions. Description Objective Methodology and assumptions Mitigation Greenhouse gases covered Implementation period Monitoring or progress indicator Results obtained Additional information Reduction of CO equivalent emissions, from 2014 to 2020, due to modernization and maintenance of lighting fixtures, electromechanical stairs and trains, and reduction of electricity consumption in the Metro facilities. The reduction in emissions avoided by modernization and maintenance of lighting fixtures, electromechanical stairs and trains seeks to reduce the electricity consumption of the Metro and is calculated by means of the following equation: ER = (AE)  (FE) Where ER- Emissions reduced in the year / [MtCOe). AE- Energy savings in the year, [MWh) FEFE of the SEN in the year, [tCO;a/MWh) Results Energy savings (MWh) FE of the SEN (tCOe/MWh) Reduced emissions (MtCO;e) Reduced emissions accumulated (MtCOe) CO, CH, N2O. From January 2013 to June 2020. Energy savings in MWh. Reduced emissions in MtCOe. Year 2018 2019 2020 Accumulated 2018 2019 5,303.11 2,559.78 0.527 0.505 0.0028 0.0013 MtCOe 0.0028 0.0013 0.0013 0.0054 2020 2.559.7 8 0.494 0.0013 0.0054 The information provided by the entity indicated that the applied technological changes resulted in non-consumed electrical energy-energy efficiency- and the corresponding contribution in reducing emissions (tCO;e). The goal of the &quot;Climate Action Program of Mexico City (PACCM) 2014-2020 is to mitigate 10 MtCOe accumulated in said period. The actions implemented during this program do not have a specific individual goal, nor a numerical one, but rather an action that to date continues to mitigate and contribute to the general goal of the PACCM Reference: Tabular format
