Macao SAR, China: Nitrous oxide (N2O) emissions from Fugitive Emissions (Energy) (Mt CO2e)

Key figures

What the numbers say

In 2024, Macao SAR, China's nitrous oxide (N2O) emissions from Fugitive Emissions (Energy) (Mt CO2e) did not change 0 on 2023 (from 0.0001 to 0.0001).

Across the 30 yearly changes before that (1994 to 2023), the average change was +0 and a typical year strayed about 0.0000587 from that (the standard deviation). This year's change was 0.0 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 0.0001 in 1990 and the biggest yearly fall was 0.0001 in 1972. 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 3% 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, Macao SAR, China had the 143rd highest value of the 187 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

A measure of annual emissions of nitrous oxide (N2O), one of the six Kyoto greenhouse gases (GHG), from fugitive emissions (subsector of the energy sector) including IPCC 2006 codes 1.A.1.bc Petroleum Refining - Manufacture of Solid Fuels and Other Energy Industries, 1.B.1 Solid Fuels, 1.B.2 Oil and Natural Gas, 5.B. 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.
