🇵🇰 Pakistan's Yearly Greenhouse Gas Emissions in CO₂ Equivalent

Pakistan's Yearly Greenhouse Gas Emissions in CO₂ Equivalent

Key Insights

2024 Emissions Profile

In 2024, methane was Pakistan's largest emissions component at around 229 megatonnes CO2e, or 47% of the national total, followed by CO2 at roughly 174 megatonnes CO2 (36%). Nitrous oxide contributed about 72 megatonnes CO2e (15%), while F-gases accounted for around 14 megatonnes CO2e (3%). All four rose over the ten years to 2024: methane by about 6 megatonnes CO2e a year, N2O by nearly 2, CO2 by around 1 megatonne CO2, and F-gases by roughly 0.8 megatonnes CO2e.

Historic Carbon Dioxide (CO2) Emissions

CO2 emissions began at around 1.3 megatonnes CO2 in 1851 and rose to roughly 16 by the mid-1930s, then climbed rapidly to about 48 in 1947. They fluctuated thereafter, falling to around 19 in 1971 before rising. Emissions peaked at roughly 241 megatonnes CO2 in 2021, then fell to around 174 megatonnes CO2 in 2024.

Historic Methane (CH4) Emissions

Methane emissions started at around 13 megatonnes CO2e in 1851 and increased gradually through the first half of the twentieth century. Growth accelerated after the 1960s, rising from roughly 43 megatonnes CO2e in 1961 to about 130 in 2005, then climbed faster. Emissions peaked at around 229 megatonnes CO2e in 2024. Methane's warming contribution since 1851 was around 91% larger than its emissions alone suggest, because methane's short atmospheric lifetime amplifies the warming impact when CH4 emissions are rising.

Historic Nitrous Oxide (N2O) Emissions

N2O emissions began at roughly 2.2 megatonnes CO2e in 1851 and rose slowly to around 5.5 by the early 1940s. Growth accelerated from the 1960s, reaching about 20 megatonnes CO2e in 1983 and around 40 in 2003. They continued rising to a peak of roughly 72 megatonnes CO2e in 2024.

Historic Fluorinated Gases (F-gases) Emissions

F-gas emissions were near zero in 1851 and remained very low through the mid-twentieth century, reaching only around 0.1 megatonnes CO2e by 1957. They rose gradually to roughly 1.5 by 2000, then accelerated after the turn of the century. Emissions peaked at around 14 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

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.

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.
