Are governments doing their “fair share”?

Climate Action Tracker Policy Brief

Published: 31/03/2015

The Climate Action Tracker has developed a new method to assess “comparable efforts” and the “fair share” of governments’ national greenhouse gas reduction proposals. Such a comparison is essential for the successful completion of an agreement on climate change in Paris in December this year, as some governments have made their offers conditional on comparable action by others.

For the first time, the method we have developed provides a comprehensive overview of many different viewpoints on what could be considered a “fair” contribution for each of over 30 countries, and for the periods 2020, 2025, 2030 and 2050. It is based on a very wide range of literature from researchers from the north and south that was initially collected for the IPCC Fifth Assessment Report (AR5).
