Lifecycles at EcoBalance 2024: Expanding Sustainability Beyond Carbon
The theme of EcoBalance 2024, Life Cycle Thinking – Beyond Carbon, reflects the need to address broader environmental impacts. This marks Lifecycles' fifth year attending the conference, drawn by its science-focused approach and commitment to pushing sustainability boundaries.
Held in Sendai, Japan, the four-day event explored critical topics like plastics circularity, agricultural supply chains, and new database structures leveraging open-source platforms and AI.
Highlights from key sessions
GHG reductions: Matthias Finkbeiner (Technische Universität Berlin) critiqued “avoided emissions” terminology, suggesting the focus shift to “GHG reduction strategies.” He noted how reduction claims can be misleading, as scenarios starting with high impacts often show greater reductions, even if the overall outcome remains suboptimal.
Plastics: A session introduced the concept of "Economic Opportunity Loss" as an environmental indicator, emphasizing the sustainability value of long-life plastics over short-life alternatives. Discussions included the need for advancements in recycling for non-PET plastics and household appliances. Anna-Sophie Haslinger presented a study on incorporating tracers into circular food and flexible plastic packaging, enabling better end-of-life sorting and recycling.
Databases: Discussions identified current database issues, including lack of traceability and incomplete information. Transparent, open-source platforms were proposed as essential for global collaboration among LCA scientists. Some highlights include: the TianGong database, a centralised free platform, EU Environmental Footprint update (EF4.0) built to improve data on chemicals, plastics, and bio-based materials, and conversations around a unified database - prompting debate on granularity and context-specific database selection.
