The national society of French railways (SNCF) has given thanks to those "preserving the planet" by travelling by train.
According to the SNCF, trains give off 30 times less CO2 than individual cars and 20 times less than planes. Thus, the national railway body is positioning itself as a clean alternative to other modes of transport.
With this in mind, the SNFC uses its campaign to thank it's "responsible citizens" for helping to preserve the planet, stating "by taking the train you avoid rejecting million tons of CO2 in nature".
To illustrate this sentiment, SNCF has partnered with TBWA/Paris to showcase the successive blooming of flowers - a timelapse that covers 200 hours.
To capture each one of the 50 varieties included, every flower was photographed once every five seconds, day and night, which accumulated in 14,000 images per flower.
In the film, every flower that blooms is accompanied by the wheezing bang of fireworks, to illustrate the celebratory nature of the campaign.
The SNCP aims to transition from diesel-powered rail to developing stations that are autonomously powered by 2035.
