While reading the ecoinvent v3.2 Change Report [Moreno Ruiz E., Lévová T., Bourgault G., Wernet G., (2015). Documentation of changes implemented in ecoinvent database 3.2. Ecoinvent Centre, Zürich, Switzerland], section 2.9 on changes in impact assessment methods caught my attention.

There was no general update for LCIA methods with the changeover from ecoinvent v3.1 to v3.2, but there have been changes to the IPCC2013 implementation, that deserve a mention here, as it will affect the LCA results of our users who work with the IPCC2013 method.

The report on page 16 explains that "ecoinvent has decided to exclude near-term climate forcers and to opt for CFs without the carbon-climate feedback effects". Also, some characterization factors (CF) had to be corrected. Therefore, "due to these significant mistake corrections and  change in methodological choices, we recommend not to use the impact assessment scores calculated for 3.1 for IPCC2013".

Apparently, when the IPCC Fifth Assessment Report (AR5) was released in 2013, due to some changes and differentiations in the method, the extraction of the most appropriate characterization factors (CFs) wasn't really trivial. Values with and without carbon feedbacks were given. For example, for methane, a GWP100a value of "28" was suggested if not considering carbon-climate feedback (CCFB), and a value of "34" was proposed including the carbon-climate feedback. ecoinvent at the time of releasing ecoinvent v3.1 had opted to go for the higher value with CCFB (see screenshot).

This decision has now been rectified and the implementation of IPCC2013 has been corrected.

Umberto NXT users who install the new ecoinvent v3.2 database and then update their existing LCA projects should be aware that the results of their LCIA may change, if they are using the IPCC2013 method. The characterization factors are attached to the elementary flows (e.g. methane, fossil) and thus when updating from v3.1 to v3.2, this may eventually lead to new LCIA results.

Please see the attached screenshots to see the difference for the elementary flow "methane, fossil". In IPCC2007 the GWP100a value was "25" (from AR4, 2007). In the implementation in ecoinvent v3.1 the CF was changed to "34". In the new release ecoinvent v3.2 it was changed to "29,7", based on the unrounded original value of "28,5" from source table 8.SM.17 in AR5 and an addition of "1,2" to account for the difference in impact on climate change between "methane, non-fossil" and "methane, fossil" as described by Boucher (2009). The GWP100a CF for "methane, non-fossil" is at "28,5" rather than using the rounded value "28" given in source table 8.A.1 given on page 731 of the AR5.

ecoinvent has published a 14-page report on the issue that explains in detail the reasoning for the changes in the implementation. This report [Bourgault G (2015). Implementation of IPCC impact assessment method 2007 and 2013 to ecoinvent database 3.2] is available to users logged in to the database in the 'Files' section (file 'IPCC implementation_v3.2.pdf'). Make sure you read it should you be using the IPCC2013 method in your LCA project.

Global Temperature Potential GTP20a and GTP100a characterization factors are now also given in the IPCC2013 implementation and can be used in addition to GWP.

The CFs are the ones without climate-carbon feedback (CCFB). According to the above report "the values of GWP and GTP with CCFB are not published for all gases [in the AR5]. Only the values without CCFB are available for CO, NOx, SO2, VOC and fossil methane. Until all CFs are available with CCFB, only the metrics without CCFB are implemented."

ifu Hamburg can assist you with your LCA project. Should you need help or wish to discuss the implication of the changes described above, please contact our Umberto Support Team.

Click on the below screenshots to enlarage them. The first screenshot is from ecoinvent v3.1 in Umberto NXT, the second one for ecoinvent v3.2 in Umberto NXT (currently being tested, release is imminent). Boths show the CFs for 'methane, fossil' from the IPCC2007 and IPCC2013 LCIA methods (other LCIA methods are collapsed and values not visible).

Data (ecoinvent v3, GaBi) / What's new in ecoinvent v3.2?
« on: December 11, 2015, 09:59 »
I am currently previewing (beta testing) the implementation of ecoinvent v3.2 LCI data in Umberto NXT LCA.

ecoinvent has published the datasets on Nov 30, 2015 and ifu Hamburg (just like other LCA software makers) now has the task to include the datasets in their software, test them in their LCA models and ship the new software package with ecoinvent v3.2 database to their customers.

An official shipping date for Umberto NXT with the new database has not yet been announced. Christmas holiday season is just not the best time of year to deliver a new product to the market...

Here are a few impressions regarding the new database. This is a subjective selection only. Those of you interested in a comprehensive summary of the changes and new items in ecoinvent v3.2 should read the official Report of Changes provided on the ecoinvent website. [Moreno Ruiz E., Lévová T., Bourgault G., Wernet G., (2015). Documentation of changes implemented in ecoinvent database 3.2. Ecoinvent Centre, Zürich, Switzerland]

  • Many updated datasets, a number of new datasets: Approximately 2200 datasets have been updated, an estimated 300+ datasets have been added. Updates may be due to changed energy input, new, split or modified geographies, new technologies, or simply due to removal of errors detected.
  • New energy datasets: News energy data for 32 regions in China.
  • Many new activity datasets for Quebec (geography CA-QC). The cooperation between CIRAIG and ecoinvent continues to yield many new datasets. Good for Canadian/Québécois users
  • New agriculture activity datasets, e.g. swine production, oat grain, maize solage, various grains used as feed.
  • New refrigerated transport datasets: refrigerated transport for different modes of transport (cooling container on ship or train, cooled goods on aircraft and cooling truck). A good addition especially for LCAs in the food sector.
  • Introduction of market groups: This will probably be the most helpful feature for many users, particularly in Europe. Market groups comprise several (national) markets. They are available e.g. for energy and heat in Europe or for China. Market group datasets merit an own post (coming soon)

It should also be noted that the system model that has been previosly recommended as the default for allocation has been renamed in ecoinvent v3.2 to system model 'Allocation at the point of substitution' (abbreviated as "APOS"). The APOS system model is explained on the ecoinvent website: "The APOS system model was previously called "Allocation, ecoinvent default". The name was changed with the release of ecoinvent version 3.2."

It was probably not a light-hearted decision by the ecoinvent experts to return to advising the use of the cut-off approach: "For users new to LCI databases, ecoinvent recommends using the cut-off system model when starting to work with ecoinvent version 3. This model can be easier to understand for first time users. The cut-off system model applies the same modelling choices as ecoinvent version 1 and 2. This system model is therefore also recommended for experienced users looking for continuity with their previous work."

As for the impact assessment methods (LCIA) it is worth mentioning that the implementation of the IPCC2013 method in the ecoinvent v3.2 release has been modified, and that its application will most likely yield results different to the ones of the the IPCC2013 method provided in ecoinvent v3.1. A more detailed description of this issue can be found in this post.

This page on the ecoinvent website is also a good starting point to learn what's new in ecoinvent v3.2

The ecoinvent Centre has announced the upcoming release of version 3.2 of the ecoinvent LCI database (read official announcement here).

Many datasets will see updates, new datasets will be added (complete list still undisclosed). What is known already, is that we can expect Chinese electricity data and datasets on refrigerated transport (important for food LCAs).

The staff at ecoinvent Centre is apparently listening to the customer voice: market groups for Europe, North America and some countries that have a regional breakdown will be introduced. This will finally mend the issue that most users faced when woking with European unit datasets with electricity mixes for all countries.

For users of Umberto NXT LCA and Umberto NXT Universal: as soon as we receive the raw data from ecoinvent, we will start converting it to an Umberto NXT master database. This process may take up to 3 months, but we will try to be as quick as possible. Expect the release of ecoinvent v3.2 in Umberto NXT in the second half of 2015. Customers with a valid Maintenance and Support Service will be the first to receive the update.

For more information, please contact our Umberto customer service team.
