In this work, an optimization problem to control world temperature anomaly is presented. In particular, the problem is related to the computation of carbon dioxide (CO2), methane (CH4) and greenhouse gases (GHG) emission reduction for the period 2025-2100 in order to maintain temperature anomaly below a selected threshold. In accordance to the last IPCC (Intergovernmental Panel on Climate Change) reports and to the discussion of COP26 meeting (XXVIth COnference of the Parties, UNFCCC - United Nations Framework Convention on Climate Change), two different threshold have been tested, with value 2° and 1.5° respectively. The application of the methodology on the case study shows its capability for the solution of the problem. Nevertheless, while with a threshold of 2° the problem has a solution that respect all the constraints imposed by COP26 discussions, a lightening of the constraints is needed to ensure a temperature anomaly below 1.5° up to 2100.

Abstract
In this work, an optimization problem to control world temperature anomaly is presented. In particular, the problem is related to the computation of carbon dioxide (CO2), methane (CH4) and greenhouse gases (GHG) emission reduction for the period 2025-2100 in order to maintain temperature anomaly below a selected threshold. In accordance to the last IPCC (Intergovernmental Panel on Climate Change) reports and to the discussion of COP26 meeting (XXVIth COnference of the Parties, UNFCCC - United Nations Framework Convention on Climate Change), two different threshold have been tested, with value 2° and 1.5° respectively. The application of the methodology on the case study shows its capability for the solution of the problem. Nevertheless, while with a threshold of 2° the problem has a solution that respect all the constraints imposed by COP26 discussions, a lightening of the constraints is needed to ensure a temperature anomaly below 1.5° up to 2100.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
