Climate Justice

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.
