Allocation of CO2 Emissions in Joint Product Industries via Linear Programming: a Refinery Example
Résumé
In joint product industries such
as an oil refinery, there does not exist a unique way to fully
allocate the refinery's CO2 emissions to its oil products. Under
certain conditions, however, refinery linear
programming (LP) models can provide a relevant and unique allocation procedure based on the marginal contribution of each oil product to the total CO2 emissions. In this particular case, the marginal CO2 allocations can be directly used for Life Cycle Assessment (LCA) purposes.
In this paper, we apply the marginal allocation methodology to the oil
refinery LP model developed by
the Institut français du pétrole (IFP) to evaluate and compare the CO2 emissions associated with different oil products. We also study the consequences of the degeneracy phenomenon on the obtained results. Finally, the limitations of this approach for short-run decisions are discussed.
