This article reviews existing scholarship on the ability of transnational city-networks to contribute to achieving a global 1.5 °C target. Its principal observation is that city-networks have become increasingly involved in pooling resources, setting agendas, sharing policies, and reporting emissions reductions, but more needs to be known about how precisely transnational city-networks are achieving verifiable emissions reductions at the urban scale. The article identifies a focus in contemporary research on direct and indirect pathways through which city-networks can potentially effect transformative change, and highlights four key issues in need of further research: burden-sharing within and across city-networks; the suite of possible policy options they are embracing and endorsing; the role and voice of marginal cities and vulnerable urban populations, and; the governance challenges related to moving from experimentation to collective global effect.

本文回顾了有关跨国城市网络为实现全球1.5°C目标做出贡献的能力的现有奖学金。它的主要观察结果是城市网络越来越多地参与资源集合，制定议程，共享政策以及报告减排量，但对于跨国城市网络如何在城市规模上实现可验证的减排量，还需要更多的了解。本文确定了当代研究的重点，即直接和间接途径可通过城市网络潜在地实现变革，并强调了需要进一步研究的四个关键问题：城市网络内部和整个城市之间的负担分担；他们正在接受和认可的一整套可能的政策选择；边缘城市和弱势城市人口的角色和声音，以及 与从试验到集体全球效应转变有关的治理挑战。
