New Study Finds Incredibly High Carbon Pollution Costs – Especially for the US and India

As a wealthy, warm country, the US would benefit from implementing a carbon tax to slow global warming.

A new study led by UC San Diego’s Katharine Ricke published in Nature Climate Change found that not only is the global social cost of carbon dramatically higher than the federal estimate – probably between $177 and $805 per ton, most likely $417 – but that the cost to America is around $50 per ton.  That’s the second-highest in the world behind India’s $90, and is also higher than the current federal estimate for the global social cost of carbon.

That’s a remarkable conclusion worth repeating.  Ricke’s team found that the cost of carbon pollution to just the United States is probably higher than its government’s current estimate of costs to the entire world.  And the actual global cost is more than 10 times higher than the federal estimate.  And yet Republican politicians think that estimate should be much lower.
