Climate Justice

What Rich Nations Owe the World—and the Future




The social cost of carbon: The most important number you've never heard of—and what it means.

The social cost of carbon: The most important number you've never heard of—and what it means.

If you’re injuring someone, you should stop—and pay for the damage you’ve caused. Why does this simple proposition, generally accepted, not apply to climate change? In Climate Justice, a bracing challenge to status quo thinking on the ethics of climate change, renowned author and legal scholar Cass Sunstein clearly frames what’s at stake and lays out the moral imperative: When it comes to climate change, everyone must be counted equally, regardless of when they live or where they live—which means that wealthy nations, which have disproportionately benefited from greenhouse gas emissions, are obliged to help future generations and people in poor nations that are particularly vulnerable.

Praise for Climate Justice

Climate Justice is a measured meditation on our obligations to one another in a warming world, and a reminder that, among all its other dizzying and distressing features, global warming is a red-hot problem from moral philosophy, asking of us, who counts and who doesn’t?”
—the New York Times

Climate Justice analyzes arguments around intergenerational equity, distributive justice, foreign aid, and consumer choices, weighing the merits and morals of policy tools like subsidies, mandates, and taxes and even more idealistic strategies, such as providing consumers with sufficient information to encourage choices that can help fend off climate catastrophe…Reading Climate Justice at this moment, when the Trump administration is doing all it can to ramp up fossil fuel emissions and end humanitarian aid to poorer countries, is unsettling. The book feels like a postcard from a time, deep in the past and yet only weeks ago, when the officials at the helm of our government understood the gravity of global leadership, cared about our neighbors, and dealt in facts….Climate change is still a global crisis, growing more urgent by the day. Inevitably, the time will come when the United States will be forced to wake up and choose to lead the world to climate solutions by example. Those who have read Sunstein’s book will be ready to participate.”
—the Washington Post Book World
