The UNFCCC Parties Paris Agreement entered into force on 4 November 2016 represents a step forward in involving all countries in mitigation actions, even though still based on a voluntary approach and lacking the involvement of some major polluting countries. The underinvestment in mitigation actions depends on market and policy failures and the absence of market signals internalizing the economic losses due to climatic damage contributes to underestimating potential benefits from global action. We highlight how crucial is the vulnerability of a country to climate change in defining the threat and action strategies. A dynamic climate-economy CGE model is developed by including a monetary evaluation of regional damages associated with climate change. By considering alternative damage estimations, results show that internalizing climatic costs changes the bargaining position of countries in climate negotiations. Consequently, damage costs should be given greater importance when defining the implementation of a global climate agreement.

Abstract
The UNFCCC Parties Paris Agreement entered into force on 4 November 2016 represents a step forward in involving all countries in mitigation actions, even though still based on a voluntary approach and lacking the involvement of some major polluting countries. The underinvestment in mitigation actions depends on market and policy failures and the absence of market signals internalizing the economic losses due to climatic damage contributes to underestimating potential benefits from global action. We highlight how crucial is the vulnerability of a country to climate change in defining the threat and action strategies. A dynamic climate-economy CGE model is developed by including a monetary evaluation of regional damages associated with climate change. By considering alternative damage estimations, results show that internalizing climatic costs changes the bargaining position of countries in climate negotiations. Consequently, damage costs should be given greater importance when defining the implementation of a global climate agreement.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
