It’s no secret that the Paris Agreement and voluntary efforts to address climate change are failing. Governments have spent three decades crafting international rules to manage the climate crisis yet have made little progress on decarbonization. In Existential Politics : Why Global Climate Institutions Are Failing and How to Fix Them (Princeton UP, 2025), Jessica Green explains why this is unsurprising: governments have misdiagnosed the political problem of climate change, focusing relentlessly on measuring, reporting, and trading emissions. This technical approach of “managing tons” overlooks the ways in which climate change and climate policy will revalue assets, creating winners and losers. Policies such as net zero, carbon pricing, and offsets primarily benefit the losers—owners of fossil assets.Ultimately, Green contends, climate change is a political problem. Climate politics should be understood as existential—creating conflicts that arise when some actors face the prospect of the devaluation or elimination of their assets or competition from the creation of new ones. Fossil asset owners, such as oil and gas companies and electric utilities, stand to lose trillions in the energy transition. Thus, they are fighting to slow decarbonization and preserve the value of their assets. Green asset owners, who will be the basis of the decarbonized economy, are fewer in number and relatively weak politically.Green proposes using international tax, finance, and trade institutions to create new green asset owners and constrain fossil asset owners, reducing their clout. Domestic investments in green assets, facilitated by global trade rules, can build the political power of green asset owners.
