• summary

  • SONEC offers a framework for relocalization of the economy but it will require very careful planning to create the right conditions for the emergence of local wellbeing economies.
  • One of the leverage points is the cosmolocal nature of SONEC, allowing the rapid, global sharing of good and best practices
  • This will be important because if SONEC is to reach its potential to awaken the sleeping giant of citizens to drive the necessary changes to mitigate the worst of the current existential polylcrisis, we will need a global synchronization of collective action at the local level.

• Earth Commission has develop principles for sharing responsibilities for cities and companies.
• Comment
  • This is implicitly a form of downscaling

• 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.

• Paraphrase
• The aim of the study is to:
  • reveal the obstacles that still prevent the application of = downscaled planetary boundaries and = downscaled doughnut economics at wide scale in the real world and in so doing
  • help identify ways to overcome the obstacles

• 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.

• Highlights
  • Downscaling seven of nine = planetary boundaries indicators
    • to the city scale-level
    • for 62 major cities in the = Middle East North Africa (MENA) region
  • Extended-Environmental Input-Output analysis is used to estimate cities’ footprints.
  • The Planetary Boundaries framework is a controlling tool for cities footprints.
  • City-level carbon footprint is higher than the national-level by 17%.

!- key question : what are the challenges of translating global scale targets into concrete and actionable targets for local actors? - in other words, how do we downscale global indicators such as planetary boundaries?

Include this in a comparative analysis of other methodologies such as Hoornweg, Hachaichi, R3.0 Thresholds and Allocations, etc.
