URBAN CLIMATE GOVERNANCE AND THE UNEVENNESS OF CITY NETWORKS: The Trajectory and Perspectives of the Global Covenant of Mayors for Climate and Energy in Chile

International Journal of Urban and Regional Research, EarlyView.
Abstract Scholars have widely discussed integrating local administrations into climate governance networks, focusing on networks such as the Global Covenant of Mayors or C40, whose members are mostly in the European Union or countries of the global North and premium cities managed by engaged administrations. Relatively little is known about urban‐scale

HOUSING RETROFIT AND THE JUST TRANSITION IN THE METROPOLIS: Governance, Redistribution, and Inequality in London and Barcelona

International Journal of Urban and Regional Research, EarlyView.
Abstract Metropolises are rapidly becoming spaces of stark inequalities. While much literature has emphasized the metropolitan scale as a driver of agglomeration economies, recent scholarship highlights either the ungovernable nature of large metropolises or the weak redistributive capacity of their governments as key causes of increasingly unequal ...
