The Future of Urban Mobility: The case for electric bus deployment in Bogotá, Colombia.

Published in Coalition for Urban Transitions, 2020

Electrifying municipal bus fleets presents a unique opportunity to reduce local pollution, improve respiratory health and reduce greenhouse gas emissions in the transport sector. Despite the promises of electric buses (e-buses), their implementation faces many challenges, especially in Global South cities such as Bogotá, Colombia.

Adapting Procurement Models for Electric Buses in Latin America

Published in Journal of the Transportation Research Board, 2019

Bus services are a fundamental component of transportation networks in Latin America, but buses often account for a disproportionately large number of environmental externalities. Electric buses (e-buses) are emerging as an effective and pragmatic option for reducing greenhouse gas emissions and local pollutants. However, e-buses are difficult to procure in Latin America because of existing procurement challenges in the region, especially as those challenges relate to forming contracts to deal with high upfront costs and unknown risks.

Etiqueta y norma de eficiencia para vehículos livianos: Beneficios, barreras y estudios de caso: Una herramienta para su implementación en países latinoamericanos

Published in World Resources Institute, 2019

Etiqueta y Norma de Eficiencia Energética para Vehículos Livianos presenta una visión general de dos políticas que los gobiernos de la región de América Latina y el Caribe pueden implementar para mejorar la eficiencia vehicular de sus parques automotores livianos nuevos. Las etiquetas de eficiencia vehicular y las normas de eficiencia energética vehicular son políticas que contribuyen a reducir las emisiones de CO 2 del sector transporte, y así mantener la temperatura global por debajo de 2°C. Chile, México y Brasil nos aportan lecciones que pueden aprovechar otros países de la región

How to Enable Electric Bus Adoption in Cities Worldwide: A Guiding Report for City Transit Agencies and Bus Operating Entities

Published in World Resources Institute, 2019

Electric buses could pioneer a new age of clean and efficient urban transport and put cities on track towards sustainability. However, electric bus adoption is not accelerating fast enough for the world to meet transport-related global climate objectives and help limit global temperature rise to below 2 degrees Celsius. The aim of this report is to fill in knowledge gaps and provide actionable guidance for transit agencies and bus operating entities to help them overcome the most common and debilitating barriers to electric bus adoption.

Barriers to Adopting Electric Buses

Published in World Resources Institute, 2019

Electric buses, which have zero tailpipe emissions, hold the potential to provide outsized air quality and climate benefits. Faster adoption of cleaner buses is an important part of the bigger climate solution, helping put cities on track towards sustainability. Despite the promise of electric buses, however, their adoption has been uneven and varied in scale. Implementation has not accelerated fast enough for the world to meet transport-related climate objectives. This report identifies and presents the main barriers that cities face when implementing e-buses, especially in the global south.

Emerging trends and innovations for electric bus adoption—a comparative case study of contracting and financing of 22 cities in the Americas, Asia-Pacific, and Europe

Published in Research in Transportation Economics, 2018

Electric buses have local environmental benefits, which has incentivized cities to transition their fleets from diesel to electric. However, the adoption of electric bus globally is geographically uneven and limited in scale. One issue is the high upfront cost of electric buses. However, few studies have analyzed the contracting and financing mechanisms that can help accelerate electric bus adoption. As part of the initial information collection process, the paper is based on real-world experiences and evidence, applies a comparative multi-case study to 22 cities in 14 countries.

Delivering modal-shift incentives by using gamification and smartphones: A field study example in Bogota, Colombia

Published in Case studies on transport policy, 2016

This study investigates the use of both monetary and non-monetary incentives delivered through mobile phones, as a way of modifying citizens’ behaviour, specifically when it comes to generating modal shift towards more environmentally friendly modes of transport such as walking and cycling.
