AlexSanterne, 
Very proud to have contributed to the #paper led by Tamara Ben-Ari et al. from @labos1point5 analysing the ~ 130 000 #academic #travels from ~160 #research units in #France over 2019 and discussing their #carbon emissions. Most importantly, the paper reports various #mitigation strategies and quantify their potential for reducing their #CarbonFootprint.

Mitigation potential of modal shift from plane to train as a function of distance. Vertical lines correspond to median time travel by train and rectangles express the uncertainty related to train speed, with 150 km/h±60 km/h. The three numbers indicate key routes in France with 1: Paris-Toulouse, 2. Paris-Montpellier and 3. Paris-Nice, contributing respectively to 14%, 7% and 16% of total domestic GHG emission from air travel.
Percentage of total (plane, train, car) travel-induced GHG reductions from single or combined options. Colors represent the intensity in GHG mitigation potential with yellow options offering the greatest potential. Each column corresponds to a specific modal shift policy, characterized by a threshold distance(and average travel time), below which a complete shift from plane to train is assumed. Modal shift options are always applied first. Each line corresponds to a specific air travel moderation policy applied at research unit scale. Moderation options are expressed in missions (equivalent to a round trip) and modal shift are considered per segment (equivalent to a one way trip). Options which correspond to actual per-capita per-year research unit median are presented at the third modality in each moderation option (i.e.,1 conference every 3yrs, 1 trip every 4 years, 5,800 km and 1 trip per yr).
