You need to accept the license of the PEF databases and then you can use them (and of course the license needs to fit to your use), for free. We are still negotiating with thinkstep about a for-payment access to the PEF databases, to use them outside of the PEF context, but this is dragging on, and I think not because of us. Non-OECD is a special option in ecoinvent (which obviously does not apply for you).
