Adjusted savings: carbon dioxide damage (% of GNI)
Definition: Carbon dioxide damage is estimated to be $20 per ton of carbon (the unit damage in 1995 U.S. dollars) times the number of tons of carbon emitted.
Description: The map below shows how Adjusted savings: carbon dioxide damage (% of GNI) varies by country. The shade of the country corresponds to the magnitude of the indicator. The darker the shade, the higher the value. The country with the highest value in the world is Mongolia, with a value of 16.04. The country with the lowest value in the world is Puerto Rico, with a value of 0.01.
Source: World Bank staff estimates based on Samuel Fankhauser's "Valuing Climate Change: The Economics of the Greenhouse" (1995).
Statistical Concept and Methodology: Pollution damage from emissions of carbon dioxide is calculated as the marginal social cost per unit multiplied by the increase in the stock of carbon dioxide. The unit damage figure represents the present value of global damage to economic assets and to human welfare over the time the unit of pollution remains in the atmosphere.
Aggregation method: Weighted average
