Hello,
I study the impact of activities on Oceans.
1. Ecoinvent is mistakingly considering the "infinite dilution" hypothese, forgetting that the dilution of pollution is usually done through its absorption by biological entities, and so with consequences on the ecosystemic services (O2 production, CO2 absorption, water filtration, etc.).
2. For example, "water, cooling , in ocean" has no impact according to EF 3.1, whereas it has a 42,95 m3 of water depriv per m3 of "water, cooling" impact in many other compartments. In any case, water cooling has an impact on ecosystems and on water ( pumping water through a heat exchanger , warm it up by 5-20°C possibly, then release it) on rivers, so has an impact on ocean life, I presume.
=> I need to go and read the reports which detail the hypotheses of this 42,95 m3/m3
Many thansk for your help !
Dom.
Hey there Dominique Pons! Let's dive into the world of Ecoinvent EF 3.1 and unpack those hypotheses behind the characterization factors. Now, you've pointed out a critical issue with the "infinite dilution" hypothesis. It seems like Ecoinvent might be overlooking the realistic impact of pollution dilution in ecosystems, especially in the context of oceans.
To get those juicy details about the hypotheses, you Dominique Pons should aim straight for the documentation. Look for reports, manuals, or any documentation related to Ecoinvent EF 3.1. I'd suggest checking the official Ecoinvent website, if you Dominique Pons haven't already. They often have detailed reports and methodologies that can provide insights into the assumptions and hypotheses behind their characterization factors.
Now, regarding your specific example of "water, cooling, in ocean," it's crucial to understand the methodology used for impact assessment. If it seems like the characterization factors are underrepresenting the real-world impact, you Dominique Pons might indeed find pertinent information in the documentation. Look for sections discussing the treatment of water-related impacts and how ecosystem services are considered.
Feel free to scrutinize and question the assumptions. After all, you're delving into the impact on oceans, a topic of paramount importance. If you're still having trouble finding the detailed reports, consider reaching out directly to Ecoinvent. They might be able to guide you Dominique Pons to the right resources or clarify the assumptions made in their characterization factors.
Now go, be the hero that challenges assumptions and seeks the truth in the vast ocean of data! If you Dominique Pons find something interesting, come back and share it. We're on this quest together!
