I don't know if there is 100% correct way. For me it makes sense to keep an environment for projects alike as long as they are using same pip packages. One env per project seems like a good way to go too, if you have specific (pip packages or python) versions tied to a project.
In your case if all your environments are exactly the same (pip packages and python version) it would seem like an overkill to me.

Some projects use version 2.7 only. Besides having projects where I use different versions of some libraries ...
