These figures use each pledge’s own scope. The chart below measures every pledge the same way, so its numbers can differ. If the latest pledge has no figure for a year, we show the last pledge that did.
Pledges to pathways
Every target Thailand has communicated, turned into an emissions pathway and set against its observed emissions.
Total greenhouse-gas emissions excl. LULUCF for Thailand, 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.
A 30.0% (unconditional) to 40.0% (conditional) reduction of emissions compared to business-as-usual emissions.

“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. “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have quantified every NDC and long-term strategy Thailand has submitted since 2015, including the pledges it has since superseded, so the evolution of ambition reads oldest to newest.
