Tonga announced its contributions to the global climate change mitigation effort on 04 Dec. 2015. The original INDC is available at the UNFCCC website . The INDCs key characteristics are:
- Change of per-capita emissions from 2010 to 2030 (average): -8%
- Per-capita emssions in 2030 (average): 2.1 tCO2/eq
- Global rank of national emissions excl. landuse (out of 195 countries): #186 in 2010 and #185in 2030.

In addition to the above default Factsheets, we produced Factsheets with alternative data sources and metrics to compare the different greenhouse gases. They are:

Disclaimer & Comments
Due to the size and quality of the underlying data-sets (and in some cases the "fuzziness" of the NDC or INDCs) we have not been able to produce "perfect" Factsheets every time. Please leave a comment if you find a glaring mistake or if you want to share an opinion about the NDC or INDC. Please be respectful.
