The cost of coating for 1 m of pipe is estimated to be €100 on average, based on the standard offshore coating system. Usually, the coating cost is cheaper for smaller size piping such as 2″ and more expensive than €100 for larger sizes. In this model, it is assumed that CRAs in...
Here we show that the release of one ton of CO2 today is projected to reduce total future energy expenditures, with most estimates valued between −US$3 and −US$1, depending on discount rates. Our results are based on an architecture that integrates global data, econometrics and climate ...
