Marshall Islands: Methane (CH4) emissions (total) excluding LULUCF (% change from 1990)

Key figures

What the numbers say

In 2024, Marshall Islands' methane (CH4) emissions (total) excluding LULUCF (% change from 1990) did not change 0 percentage points on 2023 (from 18.18% to 18.18%).

Across the 30 yearly changes before that (1994 to 2023), the average change was +0.3 percentage points and a typical year strayed about 1.15 percentage points from that (the standard deviation). This year's change was 0.3 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 4.55 percentage points in 2016. 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 27% 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, Marshall Islands had the 121st 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

Change of emissions (as %) of current year with respect to emissions in baseline year 1990 emissions of methane (CH4), one of the six Kyoto greenhouse gases (GHG), from the agriculture, energy, waste, and industrial sectors, excluding LULUCF.. The measure is standardized to carbon dioxide equivalent values using the Global Warming Potential (GWP) factors of IPCC's 5th Assessment Report (AR5). Negative values indicate that the emission level for that year is lower than the emissions level in 1990.

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 1990 emission levels as weights.
