A metric of mortality
A measure of the mortality cost of carbon (MCC) has been proposed by Bressler (2021), who describes it as a metric for “calculating the marginal mortality effects of emissions.” The metric “represents the number of excess deaths over some time period from one ton of additional carbon-dioxide-equivalent emissions.” Its value depends on the time period chosen for the calculation, and upon predicted changes in global average temperatures, which are themselves dependent on global emissions. The metric makes it possible to calculate, for example, the number additional of tons of carbon dioxide emitted in 2020 which would result in one excess death in the years 2020 to 2100. Such information, along with other measures, “can be useful in informing the decision-making of individuals” and organisations “in determining the social impact of the emissions generated by their activities” as well as guiding policy at higher levels. An insight at the individual level can be provided by estim
