American Samoa: Carbon dioxide (CO2) emissions excluding LULUCF per capita (t CO2e/capita)

Key figures

Over five years it is up 7.36% from 0.00199 in 2019 (1.43% a year on average, compounded).

What the numbers say

In 2024, American Samoa's carbon dioxide (CO2) emissions excluding LULUCF per capita (t CO2e/capita) rose 0.000034 on 2023 (from 0.0021 to 0.00214).

Across the 30 yearly changes before that (1994 to 2023), the average change was +0.00000369 and a typical year strayed about 0.0000233 from that (the standard deviation). This year's change was 1.3 standard deviations above that average, so it was larger than a typical year, though not out of the range seen before.

On record, the biggest yearly rise was 0.00298 in 1981 and the biggest yearly fall was 0.000113 in 1982. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2015 to 2024 the straight-line trend is upward, about 0.0000268 a year. A straight line explains 99% of the movement over 10 observed years.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

A straight-line projection, tested first

Extending that straight line gives about 0.0022 for 2027. We show this only because the same method, fitted on earlier years, predicted 2022 to 2024 better than "no change" would have: its average miss was 0.0000309, against 0.0000723 for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.

How it compares

In 2024, American Samoa had the 198th highest value of the 203 economies reporting that year. Higher is not always better: for some indicators the lowest value is the one to aim for. See the full ranking.

What this measures

Total annual emissions of carbon dioxide (CO2), one of the six Kyoto greenhouse gases (GHG), from the agriculture, energy, waste, and industrial sectors, excluding LULUCF, standardized to carbon dioxide equivalent values divided by the economy's population. This measure excludes GHG fluxes caused by Land Use, Land-Use Change and Forestry (LULUCF), as these fluxes have larger uncertainties.

Limitations: Global GHG emissions are currently not directly measurable, but approaches for their estimation exist, and numerous sources exist to supply data for this indicator. Reputable scientific organizations produce these data for use for research, policy analysis, climate negotiations, and broader public communications. The estimated accuracy from fossil fuel combustion and industrial processes are quite high, as quantities of fossil fuels and other emissive materials (such as cement and steel) produced are well known. For these sectors, emissions estimates are roughly accurate to within 10% when aggregated to the global level and between 4% and 35% at the country level (Crippa et al., 2023).

Regional and income-group figures are computed by the World Bank as a weighted average using population as weights.
