Good morning everybody,


Thank you for this forum. I just started working with Open LCA 1.7 in a project on packaging materials using ecoinvent 3.5.


The project objective is to make an assessment for replacing plastic with paper packaging.


My challenge is to compare, calculate and monetize the externalities of these two packaging options e. g. what are the CO2-emissions and emissions to air, soil and water and their related costs (in dollar/euro). 


My questions about Open LCA are the following:

- How can I monetize externalities with Open LCA 1.7?

- Are there any assessment methods, Plugins or Databases that would help calculating the costs in Open LCA 1.7?


I would be grateful if someone has experience with monetizing in Open LCA and could provide some help.  


Many thanks in advance,



PS: If any also of you know a suitable paper that could help me with this task, I would be very grateful for hints.

Hi Marina,

first, maybe you should switch to openLCA 1.9; for externalities, the older EPS method applies a cost assessment for impacts, otherwise (I am afraid) you will need to build a method on your own, maybe using/starting from EPS. ecoinvent contains prices for products, but these are a bit estimated and also attempt to reflect market prices, not external costs. For externalities, there are of course a number of reports from various EU projects, in 6th and 7th FP typically, see e.g. here: http://www.externe.info/externe_d7/?q=node/56.

Hth, Andreas
