Since that time three other gases were recognized as important greenhouse gases nitrous oxide (N2O), methane (CH4), halocarbons (CFCs) and tropospheric ozone.

3 The anthropogenically produced greenhouse gases include carbon dioxide (CO2) methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

Emissions of non CO2 gases are relatively uncertain, and the team concluded that the estimate of nitrous oxide is still likely to be revised significantly downwards.

Several gases, including carbon dioxide, methane, and nitrous oxide, warm the planet as their concentrations in the atmosphere increase. As the world economy grows, so do emissions of these gases, accelerating the pace of human caused climate change.

Information should be provided on the following greenhouse gases carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), to the extent the Party apos s capacities permit.

Nitrous oxide (N2O)

At a minimum, information should be provided on the following greenhouse gases carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), and sulphur hexafluoride (SF6).

Each cylinder is about 10 percent ancient air, a pristine time capsule of greenhouse gases carbon dioxide, methane, nitrous oxide all unchanged from the day that snow formed and first fell.

E. Measures targeting nitrous oxide

(i) Reduce emissions of nitrous oxide.

These rockets use experimental motors like nitrous oxide.

For Sri Lanka, the greater concern is on account of the entry into the lungs of human beings of toxic gases and particulate matter, including carbon monoxide, hydrocarbons, nitrous oxide, sulphur dioxide and airborne carbon and lead.

Nitrous oxide will remain a small component of Icelandic emissions.

Emissions of nitrous oxide (N2O) totalled 108 Gg, carbon monoxide (CO) 6.7 Gg, nitrous oxide (NOx) 2,740 Gg and non methane volatile organic compounds (NMVOC) 25,400 Gg.

Emissions of methane could be slightly reduced, while those of nitrous oxide could increase.

Other greenhouse gases and precursors Other greenhouse gases might be disaggregated if appropriate.

First, the economic challenge of controlling human induced climate change is truly complex. Human induced climate change stems from two principal sources of emissions of greenhouse gases (mainly carbon dioxide, methane, and nitrous oxide) fossil fuel use for energy and agriculture (including deforestation to create new farmland and pastureland).

(b) Adopt specific targets and timetables to limit or reduce other greenhouse gases not controlled by the Montreal Protocol, including targets and timetables for methane, nitrous oxide and fluorocarbons, in accordance with a programme of additional commitments to be negotiated and adopted by the first Meeting of the Parties.

Gases Carbon dioxide (CO2)

Doggone, that gases me!

(ii) As a limited basket (for example, all gases except those for which there is insufficient knowledge of GWP or inability to measure emissions and removals or for CO2, methane (CH4) and nitrous oxide (N2O) initially with hydrofluorocarbon (HFC), perfluorocarbon (PFC) and SF6 to be added no later than 2000) or

The Measurement of Greenhouse Gases

Nitrous Oxide N2O is also an important greenhouse gas which has both natural and man made sources.

Determination of global concentrations is difficult since nitrous oxide, which is released mainly from soils, is very heterogeneous.

Air is a mixture of various gases.

However they also act as greenhouse gases.

For 2020, emissions of all these gases are projected to increase and their importance relative to other gases will also grow.

Well, now, gentlemen... by using this special formula... which contains nitrous oxide... and which I will administer through this inhalator...

For 2020, emissions of all these gases are projected to increase and their importance relative to other gases is expected to grow.

(b) evolution of flammable, toxic or asphyxiant gases

Nitrous oxide emissions are expected to grow, mainly owing to the application of catalytic converters to reduce local and regional pollution.

CO2 represented 82 per cent of 1990 emissions, methane (CH4) about 8 per cent and nitrous oxide (N2O) about 10 per cent.

As everyone knows, air is a mixture of gases.
