It's possible to address both aspects.
I'd like to clarify something. On our end, we are responsible for the inter-ministerial mechanism, and Mr. Trocmé is responsible for the ministerial mechanism. He can provide more information on that.
What is the right balance between binding and voluntary measures? That's a great question. In fact, it's something we are trying to determine as we speak.
In terms of binding measures, it all depends on your ability to impose sanctions or penalties. I would say that's true for any statutory or regulatory measure. It all depends on the penalties: whether there are any, whether they provide a deterrent and whether they are likely to be enforced.
Currently, the French model is really quite voluntary in terms of commitment level. I'll give you an example. In theory, 50% of government-purchased vehicles have to be low-emission vehicles. In practice, however, the percentage is estimated at 12% for short term and 7% for inventory. Clearly, the reality is way off target. It all has to do with the fact that public authorities are given a certain number of exemptions, which they take full advantage of. When it comes to a mandatory approach, it all depends on political will.
As for a voluntary approach, it's a very good way to go because it encourages people not to focus solely on penalties, but also to think about the benefits of a virtuous circle and to work with us voluntarily.
