To bring more transparency to the table, Climate Resource provides what is - to the best of their knowledge - the world's most comprehensive quantification of all the 196 nationally determined contributions (NDCs) and long-term low emissions development strategies (LT-LEDS) that were put forward now by more than 80 countries, from the INDCs at the time of the Paris Agreement in 2015, all the way to the latest updated country submissions. There has been little change in global ambition in the past year, highlighting the need for increased ambition as countries submit updated NDCs for 2035.
Given the data challenges for many countries, some NDCs can be interpreted in a range of ways resulting in different quantifications of the emissions reductions implied. The authors seek to quantify the range of emissions reductions consistent with conditional, unconditional and ambiguous elements in NDCs, but acknowledge there may be different interpretations in some cases.
Climate Resource provides rankings of the countries in terms of some key indices, like which country will have the highest per-capita emissions in 2030, if its pledges are followed. Likewise, they show the rankings of country emissions in the world as of 2015 and consistent with their 2030 NDC targets.
