Environmental variables are set at a project level. When you use a environmental variable in the job and set it to $PROJDEF, during run time the value of the variable is set from the project definition. Generally connection, user name, passwords to data bases are set as environmental variables. Now is the value of the variable is changed it will automatically reflect in the job runs. User variables are defined per job and a value will have to be passed to the job during run time.

To add a word..

It has got overridding concept where by specifying $PROJDEF you may specify the value you want to pass at project level to every job. And User Variables are as simple as argument list to a job & bes the job specific.
