Our concept of ESJ assumes fair sharing of responsibilities among different actors, ensuring that those who are most responsible and capable do the most. For example, the Earth Commission has developed principles for sharing responsibilities for cities and companie

future work should calculate the Planetary Boundaries globally for each ecosystem first, and then downscale them by country.
- Comment
- In fact, Johan Rockstrom, one of the principal founders of the concept of planetary boundaries is currently working with the Earth Commission to effectively downscale fair share planetary boundaries to cities.

Yet few cities and companies currently have such targets.
- Paraphrase
- Few cities currently have science-based targets (SBT)
- Only 22 of 500 top greenhouse gas emitting companies set targets in line with SBT (Bloomberg Terminal)
- Only 110 of the top 200 cities with the highest emissions had "net zero" pledges aligned with Paris Agreement.
- Numbers are lower or missing for biodversity or other ESBs.
- Comment
- Setting such SBTs for cities is in effect downscaling Planetary Boundaries.

- Key Finding
- This paper uses machine learning to overcome unavailable carbon footprints inventories of the Global South
- which are usually hampered by:
- lack of local urban emissions data,
- reduced climate footprint, and
- shortages in climate finance.
-
using these algorithms, the author estimates 24,110 cities' carbon footprints of the Global South
- to provide a comprehensive analysis on a planetary scale,
- while allocating responsibilities according to the cities' regions and sizes.
