Routes compared
One route in the Atlas makes Biphenyl: nothing to compare yet. A comparison appears when a second route is added.
Per 1 kg of Biphenyl: inventory from each route's LCI dataset, unallocated; footprints per the functional unit of their own LCA.

ISO 14044 requires a critical review (by a panel of interested parties, ISO/TS 14071) of a comparative assertion intended to be disclosed to the public. These routes are listed side by side for screening; a statement that one is better than another needs that review. None of these routes has had such a review.
