2024 Emissions Profile

In 2024, CO₂ emissions were around 0.22 megatonnes CO₂, accounting for about 80.4% of Saint Vincent and the Grenadines' national total. Methane contributed roughly 0.046 megatonnes CO₂e, or 16.4%, while nitrous oxide accounted for around 0.009 megatonnes CO₂e, or 3.2%. CO₂ dominated emissions, with methane a distant second. Over the ten years to 2024, CO₂ rose by about 0.61% a year, methane was broadly stable, and nitrous oxide declined by around 1.36% a year.

Historic Carbon Dioxide (CO₂) Emissions

CO₂ emissions began at around 0.004 megatonnes CO₂ in 1851 and remained close to zero through the late 1930s. They then rose unevenly, reaching roughly 0.18 megatonnes CO₂ in the mid-1980s before falling back to around 0.06 in 1991. Emissions later climbed to a peak of about 0.31 megatonnes CO₂ in 2009, ending at around 0.22 megatonnes CO₂ in 2024.

Historic Methane (CH₄) Emissions

Methane emissions started at roughly 0.024 megatonnes CO₂e in 1851 and rose gradually to around 0.033 by the early 1940s. They declined into the mid-1960s, then increased steadily, reaching a peak of about 0.047 megatonnes CO₂e in 2011. Emissions remained near that level and ended at around 0.046 megatonnes CO₂e in 2024. Methane's warming contribution since 1851 was about the same as its emissions alone suggest.

Historic Nitrous Oxide (N₂O) Emissions

Nitrous oxide emissions began near zero in 1851 and rose gradually to around 0.005 megatonnes CO₂e by the early 1950s. They increased more rapidly through the following decades, peaking at roughly 0.024 megatonnes CO₂e in 1988. Emissions then declined over the long term, reaching around 0.009 megatonnes CO₂e in 2024.

Background

Greenhouse gas emissions from human activities are the main drivers of human-induced warming. In the scientific literature, human-induced emissions are often referred to as anthropogenic emissions.

Carbon Dioxide (CO₂)
Methane (CH₄)
Nitrous oxide (N₂O)
Fluorinated gases (F-gases)

Emissions from all different gases are expressed in CO₂-equivalent units to make it possible to compare the relative emissions from these different gases. CO₂-equivalents are calculated using the global warming potentials of the respective gases, in this case using a 100-year time horizon.

Total Historic Share

Crabon Dioxide (CO₂)

CO₂ includes emissions from fossil fuels and industry (FFI), and from land-use, land-use-change, and forestry (LULUCF).

Methane (CH₄)

Methane emissions are caused by human activities such as rearing livestock, agricultural practices, and fugitive fossil fuel emissions.

Nitrous Oxide (N₂O)

Common sources of these emissions are fossil fuel emissions and the agricultural use of synthetic fertilizer and manure.

Fluorinated Gases (F-gases)

Fluorinated gases are a group of gases defined by UNFCCC: hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3). Fluorinated gases are also known as halogenated gases.

Units and Measures

CO₂-equivalent emissions are expressed in the total weight in megatonnes per year. 1 Megatonne is equal to 1 million tonnes.

About the Data

National CO₂ emissions data through 2024 is from the Global Carbon Project and covers fossil sources and land-use change. Emissions data through 2024 for CH₄, N₂O and F-gases comes from the PRIMAP-hist dataset, which combines several published sources into historical emissions time series.

The Key Insights paragraph was created using a large language model (LLM) in combination with our data, historic events, and a structured approach for best accuracy by separating the context generation from the interpretation and narrative.
