While UNFCCC negotiations generally have adopted a neoliberal version of the contestedconcept of climate justice in the last 30 years, the acceptance of the Loss and Damage Fundduring COP27 indicates a possible shift in the climate justice discourse. To examine possibleshifts in the portrayal of climate justice, statements delivered by state representatives fromfive coalitions during COP21 and COP27 have been analyzed using a qualitative framinganalysis. The coalitions represent both victims of climate change and the causers of it. Theanalysis has been based on a theoretical framework consisting of six different climate justiceframes: neoliberal, distributive, intergenerational, rights-based, transformative, and ecologicaljustice. During COP21, a clear division appeared between ‘victim coalitions’ who portrayedtheir own vulnerability and partly described the injustice of climate change, and the ‘causercoalitions’ who foremost used neoliberal framings of the issue. During COP27, the divisionwas less obvious. Rights-based framings increased in prominence, but fragmentation withinthe coalitions was observed. The controversy did no longer seem to revolve aroundportraying vulnerability. Rather the division was split between the critical states demanding atransformative shift in the global climate regime, and the uncritical ones. The study indicatesthat alternative justice norms continue to break new grounds in the UNFCCC framework, butthe specific implications on politics are yet to be seen.

In June 2015, the Vatican released Laudato Si’, Pope Francis encyclical focused on environmental issues. Pope Francis acted as an advocate for a binding agreement on climate change at the United Nation (UN) Convention conferences of the parties 2015 (COP21) citing the scientific consensus on the existence and human causes of climate change. This call for action by the Pope raised the question on the role of religion in the political sphere considering whether a religious authority could influence political matters. By building on the analytical framework drawn from the work of Corell and Betsill (2008), on assessing the influence of NGO in international environmental negotiations, this thesis developed an analytical framework for accessing the influence of Religious non-governmental organizations (RNGO) to examine the influence of RNGO on COP21. The findings also shed light on the secularization debate in International Relations.
