TMCNMI Dataset
This dataset encompasses all cities members of trans-national municipal climate networks (TMCNs) defined as cross-border climate-related city-to-city initiatives ranging from SDGs, resiliency, disaster-risk management, net-zero and energy transition, etc. either as a main focal topic of their activities or as a sub-topic, in late 2024. The 40 identified networks in total produced 16,021 distinct cities (analogous urban places condensed to a single membership for each place), supplemented by 19 non-member GaWC-listed cities.Each city received a Membership Grade for every identified TMCN, effectively ranging from 0 to 6, through a point-earning scheme scaled to its degree of integration within that particular network: 0 for non-member cities, 1 for observer or non-voting membership, 2 for regular full membership, 3 for elevated membership, +1 for being a founding member of that network, +2 for being the host city of that network. The Membership Index of a city is a simple sum of a city's Membership Grade across all networks (with a theoretical maximum of 240). The Membership Index Grade is effectively the average Membership Grade of a city per network.This dataset provides a snapshot of TMCNs in late 2024 and does not represent an exhaustive, universal, or fixed record of all TMCN enrollment or stratification for any period outside of the stated date.This dataset is provided "as is" with no other warranties, express or implied, and the author disclaims all implied warranties, including any warranty of fitness for a particular purpose or any liability from the use of this dataset.This work is openly licensed by CC BY-NC 4.0.
