Yearly data from 1970 to 2024, from the World Bank.
Samoa's nitrous oxide (N2O) emissions from Building (Energy) (Mt CO2e) was 0.0014 in 2024, the latest year in the World Bank's World Development Indicators. That is up 7.69% from 0.0013 in 2014 (0.74% a year on average, compounded).
| Value | Year | |
|---|---|---|
| Latest | 0.0014 | 2024 |
| Five years earlier | 0.0014 | 2019 |
| Ten years earlier | 0.0013 | 2014 |
| Highest | 0.0014 | 2016 |
| Lowest | 0.0003 | 1970 |
| Average since 2015 | 0.00133 | 2015–2024 |
| First recorded | 0.0003 | 1970 |
Over five years it is unchanged at from 0.0014 in 2019. Since 1970 it is up 366.67% from 0.0003 in 1970 (2.89% a year on average, compounded).
In 2024, Samoa's nitrous oxide (N2O) emissions from Building (Energy) (Mt CO2e) rose 7.7% on 2023 (from 0.0013 to 0.0014).
Across the 30 yearly changes before that (1994 to 2023), the average change was +2% and a typical year strayed about 17.8% from that (the standard deviation). This year's change was 0.3 standard deviations above that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.
On record, the biggest yearly rise was 85.7% in 2007 and the biggest yearly fall was 33.3% in 2000. 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 there is no clear straight-line trend: a straight line explains less than 1% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.
Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.
In 2024, Samoa had the 166th highest value of the 197 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.

A measure of annual emissions of nitrous oxide (N2O), one of the six Kyoto greenhouse gases (GHG), from the building sector (subsector of the energy sector) including IPCC 2006 codes 1.A.4 Residential and other sectors, 1.A.5 Non-Specified. The measure is standardized to carbon dioxide equivalent values using the Global Warming Potential (GWP) factors of IPCC's 5th Assessment Report (AR5).
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 sum.
