Pledges Model: An Innovative Tool To Manage Carbon Budget distribution Across The Eu27 Member States.

PLEDGES (Pledge Limits Evaluation for Decarbonization: Goals of the EU27 Strategy) is a new simulation-based tool that for the first time attempts to include in its scope the whole carbon budget distribution across all European Union member states (EU27). The model is built using System Dynamics and presents a radial structure which interconnects the EU27 carbon budget with each Member State (MS) budget. MSs are connected with each other, allowing for the assessment of emissions compensation strategies in terms of pledge quotas assigned to each country in the case of a deviation from an established “cap policy”. In PLEDGES, the cap policy is implemented to comply with the Green Deal decarbonization objectives in 2030 (-55% emissions vs 2005) and 2050 (carbon neutrality). PLEDGES is easily customized, quick to respond and easy to use, which allows

policymakers to review decarbonization policy and compensation strategies as frequently as necessary and to analyse their implication on MSs concerning the Green Deal objectives.
