Environment and territories

An emphasis on dialogue

Aerial surveillance Rhone - Mediterranean, May 5, 2011

From choosing pipe locations to the daily running of its sites, GRTgaz makes every effort to minimise the environmental impact of its facilities and avoid disrupting local residents. The aim is to ensure the transmission network is successfully integrated into its surroundings by promoting joint solutions.

This open, consultative approach entered a new phase with the public debates that were organised for the Arc de Dierrey and Eridan projects, the aim of which is to strengthen the core of the transmission network.


Determining the best routes

  • Pipeline projects undergo in-depth impact studies into the effects they will have on the natural and human environment in order to find the best possible solutions. The parties concerned are informed of potential routes well in advance at public meetings. A public enquiry is then conducted into the chosen route, enabling it to be further improved.
  • Ground-level installations are integrated into their surroundings as much as possible to keep visual and noise pollution to a minimum and ensure maximum safety.


Reducing greenhouse gas emissions

  • GRTgaz is aiming to achieve ISO 14001 environmental certification for all of its compressor stations. The modernisation of the installed base has reduced its CO2 emissions three-fold in 10 years and its NOx emissions ten-fold. 
  • GRTgaz is also implementing solutions for cutting natural gas emissions during maintenance work.

22 compressor stations out of 26 are ISO 14001 certified:

High Environmental Quality buildings

GRTgaz's head office is a low-energy building with HEQ certification. Philogaz, the new national logistics platform, is built in line with low-energy building standards and hopes to achieve HEQ certification.

Supporting biodiversity

GRT is committed to making the preservation of wildlife, plant life and species diversity a key factor in its project operations. Because they allow animal species to move freely, its service strips act as ecological pathways that promote biodiversity.

  • GRTgaz uses best practices for crossing forests and sensitive areas thanks to its partnership with France's National Forestry Commission, the National Federation of Regional Nature Reserves and the National Museum of Natural History. 
  • As a founding member of the Linear Infrastructures and Biodiversity Club, it promotes biodiversity protection among its employees, companies active on its work sites and the general public.

On 30 January 2014, GRTgaz has received the certificate "recognized commitment SNB (National Biodiversity Strategy)" as of its voluntary commitment to biodiversity.

The National Biodiversity Strategy aims to preserve, restore, strengthen and enhance biodiversity.

The Territorial Commitments Charter

GRTgaz strives to meet expectations raised at public debates and to enhance the regional effects of its construction projects. Territorial Commitment Charters give concrete form to these ambitions.

GRTgaz is committed to:

  • conducting an ecological assessment together with local bodies and associations and proposing an action plan; 
  • defining compensation scales together with regional parties such as the Chambers of Agriculture and the French National Federation of Farmers' Unions (FNSEA), with which agreements have been reached; 
  • applying a regional best-offer clause that favours local businesses; 
  • developing partnerships with the Chambers of Commerce & Industry and job centres to foster local employment; 
  • giving residents regular updates on the progress of works; 
  • raising awareness among residents and businesses about what precautions to take to ensure the safety of pipework when planning works nearby structures.




Preserving our natural and archaeological heritage

Laying a gas pipeline also provides the opportunity to make long-term alterations that enhance the attractiveness of the areas crossed for tourists

  • As a partner of the French Ramblers' Association, GRTgaz helps to maintain, adapt and create rambling paths, as well as organise rambling outings for families. 
  • It has also signed a partnership contract with the National Institute of Preventive Archaeological Research to improve advance planning of assessments and potential excavations prior to construction work and to preserve any discoveries made.
