1. What's behind avoided emissions? a systemic stance to Vinted case study Green IO | December 2024 Laetitia Bornes Fédération ENAC ISAE- SUPAERO ONERA Université de Toulouse David Ekchajzer Univ Evry, IMT-BS, LITEM, Hubblo Université Paris-Saclay
2. Avoided impacts calculation methods… …are too reductive to account for environmental complexity… …especially when it comes to support decision-making… …and there are complementary methods and tools! ICT4S | June 2024 Page 2
3. “Our findings reveal that AI systems emit between 130 and 1500 times less CO2e per page of text generated compared to human writers.” Page 3 Ok, so the best decision from an environmental point of view is to choose generative AI rather than a freelancer??
4. Green IO – Paris 2024 | What's behind avoided emissions - a systemic stance to Vinted case study | Bornes & Ekchajzer Page 4 scenario 1 - freelancer scenario 2 – generative AI avoided impact of a human impact of AI total avoided impact
5. Green IO – Paris 2024 | What's behind avoided emissions - a systemic stance to Vinted case study | Bornes & Ekchajzer Net impacts methods - Proving the twin transition Page 5 Environmental transition Digital transition Twin transition

7. Green IO – Paris 2024 | What's behind avoided emissions - a systemic stance to Vinted case study | Bornes & Ekchajzer Page 7 E. Juge, “La fabrique des conso-marchands: une approche par les dispositifs sociotechniques dans le contexte de la consommation collaborative,” Ph.D. dissertation, Univ. of Lille, 2018. Vaayu, “Vinted Climate Change Impact Report,” Vaayu, 2021. Considered in Vinted study Not considered in Vinted study DIRECT IMPACTS Carbon emissions and pollutions due to parcel delivery and operations ENABLEMENTS Avoided impacts due to people buying second-hand instead of new items DIRECT REBOUND EFFECTS Additional impacts due to impulse buys while scrolling on the platform INDIRECT REBOUND EFFECTS Additional impacts due to sellers buying things with money from sales OTHER INDIRECT EFFECTS Shift in sellers' behaviours towards "consu-merchant" practices Partially considered in Vinted study
8. Green IO – Paris 2024 | What's behind avoided emissions - a systemic stance to Vinted case study | Bornes & Ekchajzer Page 8 (Vaayu, 2021) Missing Indirect effects Missing Social effects Uncertainties Sensitivity Complexity Deresponsbility Which environmental transition ?
9. ADEME | Environmental assessment of the direct and indirect effects of digital technology on use cases Page 9 Does that mean we should stop doing net impact assessments?
10. Green IO – Paris 2024 | What's behind avoided emissions - a systemic stance to Vinted case study | Bornes & Ekchajzer Alternative or complementary tools & methods Page 10 Systems thinking Systemic design System dynamics Value-oriented design Future studies (Sterman, 2000) (Sardar, 2010) (Jackson, 2020) (Jones & van Ael, 2022) (Donia & James, 2021)

16. Green IO – Paris 2024 | What's behind avoided emissions - a systemic stance to Vinted case study | Bornes & Ekchajzer Page 16 collectively build a qualitative overview collectively build a quantitative model identify potential rebound effects identify strategies to tackle them requisite variety & other good practices compare strategies through simulation
