Commissioning of the HSL

LISEA is committed to providing support to the regions

Thanks to its 50-year concession contract on the Tours-Bordeaux HSL, LISEA can provide long-term support for the regions in the HSL corridor. LISEA aims to limit the impact of the line on the natural environment and promote local economic development. The very first studies revealed problems associated with preserving natural habitats and protecting species so mitigation measures were incorporated into the design stage to minimize the impact of the infrastructure on the surrounding environment.

The LISEA Carbon and LISEA Biodiversity Foundations

In addition to its commitments to the State, LISEA also set up two foundations: the LISEA Biodiversity Foundation, to preserve natural heritage sites; and the LISEA Carbon Foundation, to promote energy efficiency and reduce greenhouse gas emissions. These foundations are very active. Every year from 2012 – 2017, these two Foundations have backed the creation of new projects along the high speed corridor, investing up to €5 million each. (More)

Creation of a socio-economic Monitoring Unit by LISEA

Following the creation of this Monitoring Unit in 2012, LISEA undertook to assess, evaluate and publish information on the social and economic impact this high speed line will have on regional development up until 2027 in order to help local stakeholders determine their economic development policies.  (More)
