The economic model used in the Stern Review finds that the damages from business as usual would be expected to reduce GDP by 5% based on market impacts alone, or 11% including a rough estimate for the value of health and environmental effects that do not have market prices (“externalities,” in the jargon of economics). If the sensitivity of climate to CO2 levels turns out to be higher than the baseline estimates, these losses could rise to 7% and more than 14%, respectively. Stern speculates that an adjustment for equity weighting, reflecting the fact that the impacts will fall most heavily on poor countries, could lead to losses valued at 20% of global GDP. These figures are substantially greater than the comparable estimates from most economists.
