For the last two decades, climate talks, and their top-down multinational approaches, have largely failed to curb rising temperatures. Since then, a number of subnational actors (provinces, cities, businesses, and civil society organizations, among others) have sought to tackle climate change from the bottom up. For example, at a summit in New York last year, various subnational associations pledged to take action to reduce greenhouse gas emissions. Around 75 mayors from around the world, recognizing that cities account for some 70 percent of all greenhouse gas emissions, signed a Mayors Compact to accelerate ongoing efforts to shrink their carbon footprint. And major civil society organizations and businesses also signed various pledges on a range of initiatives, from expanding energy efficiency to halting deforestation.

These initiatives are promising, but they will not do enough. According to at least one study, the subnational initiatives agreed to at last year’s summit have the potential to reduce emissions by only a fifth of the required reduction needed to keep global warming under two degrees Celsius—a threshold that if exceeded, may trigger fiercer storms and increased droughts. Subnational progress is limited because ground-up climate diplomacy has largely operated on an independent track from international diplomacy. The risk with these parallel approaches is that ground-up goals will not be incorporated into top-down ones, which risks marginalizing their efficacy.

Unlocking the potential of subnational climate action will require integration of subnational and international initiatives. And the two entities that can bridge that gap are California and Germany—two of the world’s pioneers when it comes to climate policies.

South Asia’s vulnerability to climate change and associated fragility risks calls for a regional approach to climate services. Different actors need to cooperate to share actionable climate information—the security architecture in the region would benefit.

With cities continuously more threatened by climate change-induced disasters, urban planning’s reflex response is to protect cities against nature. But what if the solution lies in working with nature instead against it? Architect Kongjiang Yu invites readers to imagine what cities could look like if they took into account ancient wisdom on spatial planning.

During the past two weeks, Antigua & Barbuda, Nicaragua and Panama ratified the Escazú Agreement, giving a major boost to the unprecedented and innovative Latin American pact that seeks to reduce social conflicts and protect frontline communities in the world’s deadliest region for environmental defenders.
