Abstract
The mitigation required to achieve the 1.5 °C goal of the Paris Agreement entails drastic
emissions reductions. The mentioned goal is of special interest for regions like the
Mediterranean where the average temperature is rising above the world average with
the consequential risk for the future viability of its different ecosystems. The objective of
this work is to analyze if the commitments of the Mediterranean Basin countries
submitted under the Paris Agreement framework are in line with the 1.5 °C goal. For
this analysis, the cumulative emissions of the current Nationally Determined Contributions
of these countries until 2030, are compared with the result obtained from distributing
the cumulative greenhouse gas emissions compatible with the 1.5 °C global
mitigation scenario between 2018 and 2100. This distribution is obtained using the Model
of Climate Justice that allocates the global emissions by using equity criteria (equality and
responsibility) that take into consideration the historical responsibility for each country, in
the period from 1994 to 2017. There are two main conclusions from the analysis of the
NDCs. Firstly, it is concluded that the Mediterranean Basin countries, as a whole, are not
in line with the 1.5 °C goal, because by 2030, 77% of the emissions budget that should be
available until 2100, based on the equity criteria aforementioned, will already have been
emitted. And, secondly, when the NDCs for each one of the countries are compared,
some significant differences in the degree of ambition can be seen.
