South America has now officially taken the lead in environmentally friendly transports. The carbon efficiency of Transmilenio is acknowledged by United Nations to provide an environmental benefit that qualifies to generate and sell carbon credits. It’s the only public transport provider in the world that is allowed to do so. Read more about Transmilenio here
The decision is getting attention all over the world, e.g. New York Times as you can read in this article.
The “bus rapid transit” (BRT) system, Transmilenio, meets the combined requirements of densely populated areas of high transport capacity and cost efficiency. 1.6 Million travellers use the 1027 BRT buses today in Bogotá. The system has 9 lines and 114 bus stops that together reach a transport capacity that outperforms many metros systems. One of the success factors is the use of high capacity 27.2 meter long Biartic buses.
I have previously written about the carbon dioxide emissions of high capacity buses as you can read here. United Nations decision to let Transmilenio generate and sell carbon credits is thus logical.The truth is that Transmillenio outperforms the public transport systems in developed cities, it use less carbon dioxide and provide service to more people. I claim that the carbon efficiency is higher than for metro, tram and train in almost all cities of the world and the service level is higher than what can be afford in the capitals of the so called developed economies.
