Integrity Matters for Cities, States, and Regions set to launch at COP28

Following a hybrid meeting on the sides of New York City Climate Week, a dedicated expert group convened by the Global Covenant of Mayors (GCoM) and WRI Ross Center for Sustainable Cities announced the forthcoming launch of the Integrity Matters for Cities, States, and Regions report in December 2023 at this year’s UN Climate Conference (COP28). 

This report is a follow-up to the flagship Integrity Matters report launched last year at COP27 by the High-Level Expert Group on the Net-Zero Emissions Commitments of Non-State Entities (HLEG). It outlines recommendations for subnational governments to ensure the credibility, accountability, and transparency of their climate and sustainability commitments while acknowledging their varied capacities and characteristics.

The report aims to: 

  • Apply the original HLEG standards to the subnational government context to retain the strong credibility, transparency and accountability recommendations while allowing for variation in local government capacity; 
  • Highlight where cities, states, and regions – as well as their affiliated net-zero alliances and initiatives – are already meeting or exceeding the minimum standards set by the flagship Integrity Matters report launched at COP27; and
  • Provide additional details on HLEG standards specific to cities, states, and regions that can enable accelerated subnational government compliance that is conducive to action implementation, especially amongst those whose climate ambitions are tempered by trailing levels of capacity and expertise.

Tasked with overseeing the development of the report, the GCoM- and WRI-convened Expert Group is composed of local and regional government representatives and practitioners, as well as partner alliances and networks. Chaired by GCoM Global Ambassador and former Mayor of Vancouver Gregor Robertson, the Expert Group also counts the participation of the Hon. Catherine McKenna, Chair of the HLEG, and observers from the UN Climate Change Secretariat. Expert Group activities commenced in March 2023, with monthly meetings and workshops to build and refine the report.
