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

Key figures

What the numbers say

In 2024, Guam's carbon dioxide (CO2) emissions excluding LULUCF per capita (t CO2e/capita) fell 0.0000136 on 2023 (from 0.0018 to 0.00179).

Across the 30 yearly changes before that (1994 to 2023), the average change was +0.0000143 and a typical year strayed about 0.000303 from that (the standard deviation). This year's change was 0.1 standard deviations below 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 0.00108 in 1971 and the biggest yearly fall was 0.000634 in 2021. 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 6% 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.

How it compares

In 2024, Guam had the 201st 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.
