Scenarios 2 and 1.5 degrees Celsius expect the reduction measures to be implemented optimally after 2020, with the lowest total cost of damage reduction. The result is the implementation of measures in the countries where it is cheapest, but that does not mean that the country of implementation has to bear all the costs. These costs can be shared and therefore funded by other countries. Financial flows could be calculated, if country-based emission allowances are based on so-called effort-sharing approaches, which are different principles of equity24,43,44, for example, load-sharing approaches in the literature on the basis of the four fundamental principles of equity, namely accountability, equality, ability and cost-effectiveness. , and regional greenhouse gas emission certificates for these categories in 2020, 2030 and 2050. The equivalency principles were also applied to carbon budgets (cumulative emissions) for the period 2011-2050 and for the period 2011-210024, based on the calculations of the FAIR45 model, see complementary figure 3, for comparison with the results of our study.

Res. Lett. 10, 105004 (2015). Like Nordhaus21, the significant change in DICE-2016 is the method of estimating the damage function. However, this adjustment has no influence on our analysis, as we replace the damage function with a new curve. In addition, as explained below, we are using more recent estimates and projections to update DICE-2013. Given the nature and magnitude of the updates in DICE-2016 and our own recalibration efforts to integrate the current data, we believe that the use of DICE-2013 as a baseline model for our study is warranted.
