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.
To fight illegal coca plantations and conflict actors’ income sources, Colombia’s president wants to loosen the ban on aerial glyphosate spraying. However, considering the dynamics of organised crime, the use of toxic herbicides will not only fail to achieve its aim, it will have many adverse effects for the environment and human health, fundamentally undermining ways to reach peace in the country. International cooperation and national policy-makers need to account for this peace spoiler.
As India grapples with the worsening impacts of climate change, the need to strengthen its adaptation efforts has become more significant than ever. Climate diplomacy and mainstreaming climate adaptation into the most vulnerable sectors could provide some solutions to overcoming barriers, such as the lack of sustainable funding.
“Climate Security risks will materialise in very different ways and forms, whether we talk about Lake Chad or about the Arctic, Bangladesh and the Small Island Developing States,” said the EU’s Ambassador to the United Nations in New York, Joao Vale de Almeida, in his opening remarks. “But for the EU, there is no doubt, as underlined in 2016 in our Global Strategy, and reaffirmed by the 28 Ministers of Foreign Affairs, that climate change is a major threat to the security of the EU and to global peace and security more generally,” he said.
The challenges facing the international community are growing while the willingness to cooperate seems to be waning. Foreign policy must help bridge this gap. One way to accomplish this is by pushing forward a major achievement of multilateralism: the 2030 Agenda and its 17 Sustainable Development Goals. At a side event during the 2019 High-Level Political Forum, diplomats and policy experts discussed the role of foreign policy in the global sustainability architecture.
