Yet, there remains a pressing need for practical guidance on developing assertions of fairness in national mitigation contributions. The Paris Agreement mandates that subsequent nationally determined contributions (NDCs) submitted under Article 4 represent a progression compared to previous NDCs. Further decisions under the Paris Agreement mandate that NDCs include clear and transparent considerations of fairness, as recalled in the first Global Stocktake. We propose a practical approach to this, comprising a set of 'entry points' that represent key stages where decisions are taken in 'fair share' quantifications, from interpreting foundational principles to selecting indicators and presenting results. By bridging the gap between scholarly debates and practical application, this work supports the integration of clear and transparent fairness considerations into climate policy commitments. We demonstrate the use of our approach through a case study. 2025-01-16 published Institute of Physics Publishing (IOP) doi:10.1088/1748-9326/ada45f 3176 3596 222 254 250 public Environmental Research Letters 20 2 e024012 TRUE 1748-9326 Enabling and Leveraging Climate Action Towards Netzero Emissions (ELEVATE, HE 101056873) Bridging current knowledge gaps to enable the UPTAKE of carbon dioxide removal methods (UPTAKE, HE 101081521) yes info:eu-repo/grantAgreement/EC/HE/101056873/EU//ELEVATE; info:eu-repo/grantAgreement/EC/HE/101081521/EU//UPTAKE info:eu-repo/semantics/article info:eu-repo/semantics/openAccess
