Each ton of CO2 costs the company $ 417

The social cost of the CO2 produced, that is the total damage it causes to society, ranges from 117 dollars to 805 per ton, with an average of 417 dollars per thousand kilos. The 3 countries at the top of the emissions ranking - India, China and the USA - are those who will lose more in the face of climate change. Following are the Gulf countries, like Saudi Arabia. This is supported by joint research by the European Institute for Economics and the Environment (EIEE) and the University of California, published in the journal Nature Climate Change. 

For the first time, a group of researchers has developed a data set that allows to quantify the social cost of carbon - that is the economic damage deriving from carbon dioxide emissions - for each of the approximately 200 countries in the world.

In addition to revealing that some countries are likely to be affected more than others of the emissions, the results of the study also show that the social carbon cost at the global level is higher than that normally taken into account. "We all know that carbon dioxide produced from fossil fuels produces, and will produce in the future, effects on people and ecosystems around the world - explains Kate Ricke, of the University of California San Diego - however, since these impacts are not considered in the market prices, an environmental externality is created that is not paid by those who consume energy produced from fossil fuels.We are therefore not aware of the true cost of this type of consumption ". 

"Our analysis shows that the social costs of climate change will be high for many states, including those, such as the USA and the Gulf countries, which are traditionally far from climate policy leadership," emphasizes Massimo Tavoni, Associate Professor at the Milan Polytechnic, Director of EIEE - European Institute on Economics and the Environment and author of the research -. In addition, 90% of the world's states will record losses due to climate change, and this can not but exacerbate international inequalities and tensions. Many countries have not yet recognized the risks posed by climate change. Our study tries to fill this gap ".
