Cities are stepping into a new role in the climate fight, one that goes beyond cutting emissions to actively removing CO2 from the atmosphere and effectively becoming carbon sinks. That is the thrust of a newly released implementation guide from the City CDR Initiative, a consortium of global cities, research groups and developers outlining how municipalities can embed carbon removal into everyday urban governance.
The report argues that while carbon removal technologies often grab headlines, the real bottleneck is institutional. “Progress on carbon removal depends less on the maturity of individual technologies than on governance clarity, institutional coordination and planning capacity,” the authors write.
Rather than treating carbon dioxide removal as a standalone climate fix, the guide urges cities to weave it into existing municipal functions such as waste management, water systems, building codes and land-use planning, where political authority already exists. “CDR should not compete with existing urban policies; it should strengthen them,” the report says, pointing to opportunities to deliver co-benefits including cleaner air, job creation and urban resilience.
Based on assessments of 15 global cities, the initiative finds that only about a third are ready to deploy carbon removal projects at scale today, while most could reach that point within two to three years with targeted capacity building. Nature-based solutions such as urban forestry, soil carbon and green infrastructure are framed as a universal entry point, particularly for cities lacking heavy industrial infrastructure.
The guide also addresses the political sensitivities surrounding carbon removal, warning that poorly governed projects could undermine public trust or delay emissions cuts. Becoming a so-called carbon sink city, it concludes, is “an institutional, social and economic project,” not a quick technological fix.
For city leaders under pressure to deliver visible climate results, the message is pragmatic. Carbon removal can start now, but only if it is grounded in local priorities, transparent accounting and durable public support.
