NDC Quantification
Sierra Leone’s 2035 pledge: A 36.2% reduction of emissions compared to business-as-usual emissions.
For total GHG emissions excluding LULUCF, that is 28–126% above 2019 levels by 2035.

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.

“Economy-wide”: the target covers all major sectors. “incl. LULUCF”: includes land use, land-use change and forestry. “SAR”: gases aggregated using IPCC Second Assessment Report 100-year global warming potentials. “2006 IPCC Guidelines”: the submission does not say which global warming potentials it uses.
Submission history
We have quantified every NDC and long-term strategy Sierra Leone has submitted since 2015, including the pledges it has since superseded, so the evolution of ambition reads oldest to newest.
