It depends on the car seat and the van, do you know exactly which car seat it is? At 15 months I’m guessing he’s still rear facing so you’ll also need to make sure you can turn the air bags off in the van. Your best bet will be getting in touch with either the retailer you bought the car seat from or Joie directly for guidance on this one

Don't you have a car that you're taking with you? As surely you do if u have a car seat?
@Rebecca the car we had was a company car, now that we're moving away, the car has gone back
If the airbag can go off, and he is rear facing yes. Also check the vans manual as most vans only allow car seats on 1 out of 2 front seats, usually the outer seat closest to door x
Is he rear facing? If he is he is allowed in the front of the van with the airbags off.
