Responsible institution Description Objective Methodology and assumptions CDMX Environment Secretariat The public bicycle system of Mexico City (Ecobici) is a program that allows the reduction of CEI emissions and criteria pollutants, in addition to having economic and social benefits, such as the reduction in travel times, lower cost, exercise and sustainable mobility option. The program was implemented in February 2010 with 84 cycle stations and 1,200 bicycles. In 2013, a study was carried out by CTS Embarq in order to calculate a mitigation potential with respect to the baseline (if Ecobici did not exist). This study has made it possible to make projections of use and environmental benefits. Other very positive impacts of the program are physical activity and the reduction of negative health impacts due to poor air quality. The information generated in the CTS Embarq report demonstrates the different benefits that a public bicycle system can bring to cities (CTS Embarq, 2013). Ecobici is the public bicycle system in Mexico City that has integrated the bicycle as part of the essential of mobility. Its objective is to offer the inhabitants of the city and its surroundings a comfortable and easy access system for the use of access bicycle transfers, which is a mode of transport aimed at the inhabitants of the capital and its surroundings and tourists.. Based on the information on the trips made in Ecobici in 2010, 2011 and 2012, the total number of kilometers traveled by the users of this public bicycle system was estimated. Using the modal distribution of the trips that users substituted for Ecobici, the person-kilometres of travel avoided by private car, shared car, taxi and motorcycle were obtained. The kilometers traveled by car were divided by the average occupancy, which is equal to 1.4 people per vehicle, to obtain the distance traveled by vehicles. Said methodology started from a base line of emissions previously carried out for the year 2009 by CTS to obtain the average CO emissions for each mode of transport. Subsequently, a Bottom-up approach is used, since it starts from estimates of the individual activity and is grouped to obtain the total impact. The reduction in emissions is derived from modal changes in transport (CTS Embarq, 2013). LB = FV  DT x FE Where LB- Reduced emissions (MICO,0). FVI- Vehicle fleet. DT-Average annual total
