Can you be more specific about which version of ReCiPe method it is. I have inquired about it in OpenLCA and they said that Ecoinvent ReCiPe methods is v1.08. I would like to know if you can confirm this.

Dear J Adonai, 

 

This is a general comment for all users, we are not always aware of how ecoinvent and ecoinvent related methods etc. are displayed in each and every LCA software. We are threrefore grateful when, as you did, we can recieve a screenshot or a very specific indication of what a user is exactly looking at. We thank in advance all users for the understanding and their help.

 

The ReCiPe version that is used in ecoinvent is ReCiPe 2008:

 

Goedkoop M., Heijungs R., de Schryver A., Struijs J. and van Zelm R. (2009)
ReCiPe 2008 - A life cycle impact assessment method which comprises
harmonized category indicators at the midpoint and the endpoint level / Report I:
Characterisation. Ministerie van VROM, Den Haag (Netherlands), OnlineVersion
under: www.lcia-recipe.net.

 

You can read more about the implementation in ecoinvent in:

Dear Niels,

Which datasets in particular do you have in mind? And which impacts? In case of lorry the impacts with refrigeration are app. 18% higher (GWP) which is in line with other studies done on refrigeration.

 

Yes, there is a sectorial report available. You can download it from the ecoquery (see the attached screenshot). Plus see a link to a poster presented in one of the scientific conferences we attended in 2015 (http://www.ecoinvent.org/files/150430_levova_poster_modular__parametrised_

life_cycle_inventories_of_transport_of_goods_in_need_of_atmosphere_control.pdf) on the topic – Figure 4 shows the influence of the added refrigeration per 1kg of fruits (consumer mix).

I hope this explains your observations.

I was surprised about the extremly higher impacts of refrigerated transports compared to normal transports. You are named as the data generator. Can you provide more details than in the meta information how this was modelled? Is there a report available for this? Where on the cited webpage is this information provided?

Dear Evelin, 

 

To see the differences between the methods you can acess the ecoinvent database onlineif you never accessed before pelase read here, in the files section you can download the zip file ecoinvent 3.3_LCIA_implementation.7z. The zip contains, amongst other, the list of LCIA methods implementation (including characterisation factors) in excel format and its PDF documentation which contains a section dedicated to IPCC. You can also find specific excel files for IPCC2007 and 2013.

Hi,

I had thougth the global warming potential should be somewhat the same over all methods. Yes, methane became 28 (instead of 25), and N2O dropped significantly, but where do the huge differences come from?

For example: market for sugar, from sugarcane (GLO)

CML 2001: 1,1667 kg CO2e/kg

IPCC 2007: 1,141 kg CO2e/kg

IPCC 2013: 1,6389 kg CO2e/kg (!!!)

IPCC 2013 is 44% higher - have I missed something?

 

Please help!!!

Dear Emily, 

 

I would reccomend you to look into version 2 report 13 III Lanfills. Read here on how to access version 2 reports, if you never accessed ecoinvent online please read here

Dear J Adonai,

 

You can download the list of all LCIA methods including all the impact categories as well as list of selected LCI cumulative results provided by ecoinvent here: "LCIA methods in ecoinvent 3.3". To know what is available in OpenLCA please contact their support directly.

The carbon footprint for the Swiss market mix of biogas. I am not aware of any imports to Switzerland. Please explain why there is no Swiss dataset in the Top 5.

- Why is there nearly no Swiss biogas in the Swiss market mix?
