Sled-dog racing is a "low impact" activity as the only mark it leaves in nature is the footprint of the musher and his dogs in the snow: A mark which will disappear with the first gust of wind or snowfall.
Also, in the collective imagination, sled-dog racing conjures up the harmony between man and nature, and therefore a certain form of respect for the environment. Generally speaking, La Grande Odyssée Savoie-Mont-Blanc is a responsible event and a way of practicing sustainable development.

On an ecological level

• LGO saves energy by optimizing its entire staff’s travel before, during and after the race (minimum of vehicles, maximum of car-sharing, travel by train where possible, etc.), as well as competitors during the race (road map, organization of convoys, etc.).
• LGO limits use of paper by sending almost all documents it produces by email and printing, where necessary, as many documents as possible on both sides of the paper.
• LGO favors biodegradable and recycled material (recycled or PEFC-certified paper, barrier tape made from starch, recycles its print cartridges, etc.).
• LGO makes up for its CO2 emissions through the CO2 Solidaire program developed by GERES.

On an social level

• LGO encourages associations which want to show off educational and/or solidarity projects through the Grande Odyssée Savoie-Mont-Blanc (Association Rêves, Association Prioriterre, Association Natur’a-venir, etc).
• LGO has an impact on local communities by allowing professionals and inhabitants from the various resorts to work on a single wide-ranging and uniting project (traditionally sporting events involve only one resort). From production of routes to design of safety plans via communications and preparation of the slopes, a large number of people are involved at all resorts, in dozens of work and coordination meetings.
• LGO uses disabled workers calling on ESAT (Occupational Assistance Establishments and Services), particularly in the manufacturing of signposting equipment.

On an economic level

• LGO participates in the development of the local economy, particularly tourism, as a result of its Grande Odyssée trips offered to partners as well as the general public (through resorts).
• LGO favors local service providers, since 50% of La Grande Odyssée’s services providers are based in Savoie and Haute Savoie.
