These figures use each pledge’s own scope. The chart below measures every pledge the same way, so its numbers can differ.
Pledges to pathways
Every target Costa Rica has communicated, turned into an emissions pathway and set against its observed emissions.
Total greenhouse-gas emissions excl. LULUCF for Costa Rica, AR6 GWP-100. Shaded bands show the range of published interpretations of each pledge.

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.
An absolute target of 14.0 (unconditional) to 11.4 (conditional) Mt CO2-e/yr.

“Economy-wide”: the target covers all major sectors. “All gases”: covers the full basket of greenhouse gases. “incl. LULUCF”: includes land use, land-use change and forestry. “AR5”: gases aggregated using IPCC AR5 100-year global warming potentials. “GWP unclear”: the submission does not say which global warming potentials it uses.
Submission history
We have quantified every NDC and long-term strategy Costa Rica has submitted since 2015, including the pledges it has since superseded, so the evolution of ambition reads oldest to newest.
