What are the main

man-made greenhouse gases?        2011

The greenhouse gases

that humans do emit directly

in significant quantities are:

• Carbon dioxide (CO2).

Accounts for around three-quarters

of the warming impact of current

human greenhouse-gas emissions.

The key source of CO2 is the burning of fossil fuels

such as coal, oil and gas,

though deforestation is also a very significant contributor.

• Methane (CH4).

Accounts for around 14% of the impact

of current human greenhouse-gas emissions.

Key sources include agriculture

(especially livestock and rice fields),

fossil fuel extraction

and the decay of organic waste

in landfill sites.

Methane doesn't persist

in the atmosphere as long as CO2,

though its warming effect

is much more potent

for each gram of gas released.

• Nitrous oxide (N2O).

Accounts for around 8%

of the warming impact

of current human greenhouse-gas emissions.

Key sources include agriculture

(especially nitrogen-fertilised soils

and livestock waste)

and industrial processes.

Nitrous oxide is even more potent

per gram than methane.

Fluorinated gases ("F gases").

Account for around 1% of the warming impact

of current human greenhouse-gas emissions.

Key sources  are industrial processes.

F-gases

are even more potent per gram

than nitrous oxide.

methane,

the main component of natural gas        UK / USA

Methane

is a far more powerful greenhouse gas

than carbon dioxide,

though it doesn’t last

nearly as long in the atmosphere.

Still,

over a 20-year period,

one pound of it traps as much heat

as at least 72 pounds of carbon dioxide.

Its potency declines,

but even after a century,

it is at least 25 times

as powerful as carbon dioxide.

When burned, natural gas emits

half the carbon dioxide of coal,

but methane leakage eviscerates this advantage

because of its heat-trapping power.

Turkmenistan > methane emissions        UK

Methane leaks from Turkmenistan’s

two main fossil fuel fields

Most of the facilities leaking the methane were owned

by Turkmenoil, the national oil company, Kayrros said.

Further undetected methane emissions

will be coming from Turkmenistan’s

offshore oil and gas installations in the Caspian Sea,

but the ability of satellites to measure methane leaks

over water is still being developed.
