The tracker is a collaboration between two German organisations, Climate Analytics and New Climate Institute, that was founded in 2009 and is based in Berlin. It tracks data from 36 countries plus the EU, covering about 80% of global greenhouse gas emissions and about 70% of the world’s population.
The tracker quantifies and evaluates climate change mitigation commitments, and then assesses whether countries are on track to meeting them. It aggregates country action to the global level, determining the likely temperature increase by the end of the century. The tracker also develops sectoral analysis to illustrate required pathways for meeting the global temperature goals.
The national actions that are tracked are:
From this data, the tracker calculates the gap between the pledges made now and the work that is needed to meet the goals, and the consequences for global warming if there is a shortfall. This uses the Model for the Assessment of Greenhouse Gas Induced Climate Change (MAGICC), developed by the US National Center for Atmospheric Research and the Potsdam Institute for Climate Impact Research.
