A pathway to a climate change agreement in 2015: options for setting and reviewing GHG emission reduction offers

The United Nations Framework Convention on Climate Change (UNFCCC) Parties need to put forward emission reduction offers as part of the 2015 climate change agreement that is currently being negotiated. This paper suggests options for the design of this process, including the content of the offers and how they will be reviewed.

A core part of that architecture is mitigation, or the reduction of greenhouse gas (GHG) emissions. How should Parties fairly and ambitiously commit to reducing GHG emissions in a way that builds confidence in the international system and that drives collective action in order to keep global temperature rise below 2° Celsius? The authors argue that the best of the available approaches needs to be brought together to create a new mitigation architecture that both drives ambition and equity and is deeply embedded in national economies.
