Born in Narbonne the 18th July 1983, Yann MONGABURU obtained a Master in Public Policy Analysis at the Institute of Political Studies in Grenoble. He is agent of social security in the Family Allowances Fund of Grenoble since 2012. Militant environmentalist, he participated actively in the election of Eric PIOLLE as mayor of Grenoble in March 2014.

In this sense, he became delegate member in the intercommunal council, vice president of Grenoble-Alpes Metropolis in charge of the transport sector and president of the Grenoble transport autohority (SMTC) in Grenoble. He promotes the approach “soothed metropolis”, which limits traffic speed to 30km / h in 43 of the 49 Grenoble municipalities.

Wishing to create a multimodal metropolis, Yann MONGABURU set the target to triple the cycling modal share part by 2020, as he aimed to improve the performance of the public transport network through experimentation and innovation on the existing tramlines, the rapid transit busses and the on-call transportation in sparsely populated areas and mountains.

Particularly sensitive to air quality related issues, he managed to cooperate with the prefect of Isere in order to implement a protocol of agreement between local authorities for pollution episodes management involving all stakeholders in Grenoble. He is also part of the first center of urban distribution initiative, decisive tool to organize progressive output diesel.

He wanted to offer a fair and equitable tarif for all users in order to make daily displacements affordable even for the most precarious public. His engagement and vigilance allows almost 25 000 people to benefit from pricing adapted to resources (subscriptions 2.5 € – 19.7 €  per month) and young people (18-24 years) to pay only € 15 per month, making the Grenoble network one of the cheapest in France.

Yann Mongaburu is also the director of the National french association of Transport Authorities (GART) and of the cycling cities and territories club to represent the Grenoble mobility on a national level.



Carina Borgström Hansson joined WWF in 2005 as an expert on sustainability indicators and the ecological footprint. As a member WWF’s global footprint steering group she has been pioneering the development of strategic approaches to reduce humanity’s  ecological footprint. This includes approaching the accelerating destruction of biodiversity and ecosystem services in WWF’s priority places by engaging with drivers far beyond these places, such as urbanization and consumer attitudes and lifestyles.  In 2011 she initiated WWF’s global city engagement with a focus on promoting urban solutions for attractive, equitable, and sustainable lifestyles. Carina leads WWF’s sustainable cities flagship initiative the Earth Hour City Challenge which recurrently invites cities to publically report their commitments and actions for the transition towards a sustainable and renewable energy based economy or a so called One Planet Future (ie where we all can live well within the ecological capacity of our one living planet).
