The Covid 19 pandemic has created human suffering on a global scale, but also a strange window of opportunity to rethink how we live, work and play. For the time being, calls for a green recovery that builds back better by cutting greenhouse gas emissions, protecting the environment and creating a fairer, more equitable society have become commonplace. This could help to build new momentum in international efforts to combat climate change and rebuild lost trust and goodwill between parties in the intergovernmental negotiations through new collective approaches. If we are serious about creating a better future, transitional justice can provide some important guidance on the way forward. It would provide a framework to deal with past inequitable use of the global environment in a transparent and inclusive manner and shape a new path of international solidarity and collaboration. This paper provides a brief overview of the concept of transitional justice, its techniques and potential relevance in the climate negotiation context.
