What role for cars in tomorrow’s world?

Abstract in English: 
What lies ahead for cars? The need to improve air quality and the quest for more fluid means of mobility, and sometimes dogmatic viewpoints have led some to want to exclude cars from towns.
Despite the undeniable progress that has been made to mitigate its impact, cars remain a source of undesirable externalities. In France, transport represented 26.9% of greenhouse gas emissions in 2013 and 28% of particulate emissions in the Île-de-France region.
Congestion in city centres leads to increase in both of these emissions and a considerable loss of time (estimated at 38 minutes per day in Paris) and money for those who drive.

The future of electricity transmission : cost-benefit analysis of a biodiversity-friendly vegetation management in forest corridors

Abstract in English: 
Vegetation is a threat for electricity transmission when overhead high-tension lines are crossing forest areas. For this reason, Transmission System Operators (TSO) often proceed by regular vegetation destruction in order to prevent any electrical blackout that could be triggered by trees, by contact or by fall.

The innovative LIFE Elia-RTE project (funded partly by EU) decided to think about alternative methods that could ensure not only electrical safety, but also enhance biodiversity ! These methods should aim at protecting species and natural habitats encompassed by the European Natura 2000 legislation. Indeed, for a good ecological state, we need core areas and connection corridors. This is where high-tension lines have a strong potential to be converted as green corridor for biodiversity.

On a 30 years timescale, biodiversity-friendly vegetation management has been estimated to be 1.4 to 3.9 cheaper than traditional vegetation management ! And not only for its cost savings, it also brings many other benefits.
