Dear Dr. Joan,

The life cycle impact assessment (LCIA) methods aim to connect, as far as possible, and desired, each life cycle inventory (LCI) result (elementary flow or other intervention) to the corresponding environmental impacts.

Pls find the following paper link,

Dear Dr Mendoza,

Going beyond the IMPACT 2002+ method, I think that some of the works performed by Prof Kojimatsu could be of interest: http://www.kt.depe.titech.ac.jp/page3.html

Besides, some works from

Thomas Gibon: https://www.researchgate.net/profile/Thomas-Gibon

Laurent Vandepaer: https://www.researchgate.net/profile/Laurent-Vandepaer

Ben Amor: https://www.researchgate.net/profile/Ben-Amor

are surely relevant.

From the LCA angle to evolve LCIs, I think Mutel's advances with Brightways2 are extremely relevant: https://www.researchgate.net/profile/Chris-Mutel

Keep in touch

Thanks Diego García-Gusano

Dear Joan Manuel F. Mendoza

Recently a tool has been provided - using Python, available on GitHub - to perform prospective LCA by making use of the outputs of integrated assessment models (IAMs, both IMAGE and REMIND) to modify the background life cycle inventory (LCI) database ecoinvent using different socio-economic pathways. Please have a look at https://github.com/polca/premise.

Further, this recently published paper in Renewable and Sustainable Energy Reviews provides a description as well as a couple of case studies of the tool:

Hope this helps,

Dear Tom Terlouw

Thank you very much for yoru answer.

I have checked the premise tool and it is very interesting. It is one of the tools I have on my radar.

Thank you!

All the best,

Joan

Dear Joan Manuel F. Mendoza

I think it depends on your research question and what level of detail that you intend to model. A few colleagues and myself have modelled the carbon footprint impacts of different electrification scenarios for Swedish passenger car travel. Instead of building a prospective LCA-framework fully integrated with an IAM, we designed a model based on a regular LCA (the GREET-model), IAM-results for two decrabonization scenarios and studies on disruptive changes in different manufacturing industries relevant for vehicle and battery manufacturing.

The approach is described in this paper:

Article Carbon footprint impacts of banning cars with internal combu...

With that said, I also find the premise-tool very interesting for economy-wide studies and will also look into possibilities of a closer integration with IAMs in future studies.

Best,

Johannes

Good morning Johannes Morfeldt

Thank you for your reply.

We are aiming at modelling the life cycle environmental impacts of alternative decarbonisation scenarios for the iron and steel industry. To do so, we are exploring the adaptation and integration of LCI/LCIA data into LEAP.

I will read your article for additional insights based on your approach. Thank you very much for sharing it!

All the best,

Joan Manuel

Dear Joan,

In a recent paper I deployed an LCA model for passenger vehicles which read in the carbon price from NEMS which was then translated into a feebate and fed back to NEMS. As such, the feebate for different vehicles was set according to their entire life cycle footprint. The feebate then influenced purchase behavior in NEMS. For more information please see here: https://www.nature.com/articles/s41467-021-27247-y

Thanks!

Dear Paul Wolfram

Thank you very much for your reply. We will certainly revise your work.

Thanks for sharing it.

All the best

I would recommend leveraging the Consequential LCA approach for including predictive analysis into one's work. Reinout Heijungs and Sangwon Suh have both contributed immensely to any one of your questions/thoughts. Reframing the fundamentals oneself, for example, might be the best way to address one's specific domain/application. Heijungs and Suh's Computational Structure of LCA, in my opinion, is the only place to start.

Have a look at the following paper for theoretical background:

Thanks for sharing it Aryan.

We estimated embodied energy and carbon emissions from urban water system. It shows integration of life cycle inventory with energy models to estimate baseline sustainability status of a developing urban water system. The link is given below:

Thanks Rajhans, we will have a look at it.

In LEAP, you can calculate process-based emissions as well. You just need to follow the IO approach and revise your tree structure. Of course, the emissions coming from some consumption materials (mostly agents, catalysts and some chemicals used as medium) cannot be calculated if you did not define specific key assumptions. Implementing the LCA approach to energy modelling is difficult if you are using generalised energy modelling tools where the references are too old to find; which surely will be needed to define technology types, and system boundaries as well as to understand the working principle of the energy modelling tool.

Implementing LCA to the simulation models (like LEAP)will be easier compared to other options. Since most simulation modelling tools are working on merit order. However, the situation is different when it comes to optimisation models. You need to fully grab the interlinkage of technologies (i.e. how the system is designed and operates), otherwise, it will be a common mistake that I saw in LCA papers, which is disregarding the operation principles of the model. I hope this helps.

Thanks @Hasret Sahin for recommending LEAP. We are currently using it as the baseline energy modelling tool for the integration of LCA considerations.

All the best.
