For nbclient environment variables should be getting passed to the kernel process that gets launched by nature of being a subprocess. However it doesn't guarantee that the kernel preserves said environment variables in it's launch configuration. For the ipython kernel it works just fine:

$ TEST=5 papermill --log-output envtest.ipynb envtest.ipynb 
Input Notebook:  envtest.ipynb
Output Notebook: envtest.ipynb
Executing notebook with kernel: python3
Executing Cell 1---------------------------------------
Ending Cell 1------------------------------------------
Executing Cell 2---------------------------------------
'5'
Ending Cell 2------------------------------------------

with an example using papermill to execute a notebook with nbclient that print the TEST environment variable.
