NDC Quantification
Mauritania’s 2050 pledge: A 95.3% reduction of emissions compared to business-as-usual emissions.
For total GHG emissions excluding LULUCF, that is 78% below 2019 levels by 2050.

Scope & conditionality
Coverage and conditionality are derived from our structured assessment of each submission. Each target is shown as submitted, in its own scope. The chart above measures every pledge the same way (AR6, excl. LULUCF), so its numbers can differ.
Unconditionally: A 11.0% reduction of emissions compared to business-as-usual emissions. Business-as-usual emissions: 17.3 Mt CO2-e/yr. Conditionally: A 92.5% reduction of emissions compared to business-as-usual emissions. Business-as-usual emissions: 17.3 Mt CO2-e/yr.

“Economy-wide”: the target covers all major sectors. “incl. LULUCF”: includes land use, land-use change and forestry. “AR4”: gases aggregated using IPCC AR4 100-year global warming potentials. “AR5”: gases aggregated using IPCC AR5 100-year global warming potentials.
Submission history
We have quantified every NDC and long-term strategy Mauritania has submitted since 2015, including the pledges it has since superseded, so the evolution of ambition reads oldest to newest.
