What is the main greenhouse gas?
Rice production is another major source of greenhouse gas emissions.
It is already the biggest producer of greenhouse gas emissions.
In November the EPA announced new greenhouse gas reporting rules for the oil and gas industry.
But us researchers found that shale gas Wells leak substantial amounts of methane, a potent greenhouse gas.
That's because the additional processing and shipping of liquefied gas would put even more greenhouse gas pollution into the atmosphere.
Emissions of nitrous oxide (a very powerful greenhouse gas) caused by the application of nitrogen fertilisers.
In addition, wetland soils are known for methane emission, a greenhouse gas.
As the tundra melts, methane, a strong greenhouse gas, is released, causing more warming.
However, the greenhouse gas emissions in Britain and Germany distinctively reduced by 7.8% and 17.4%, respectively.
Carbon dioxide is the second most important greenhouse gas (after water vapour), trapping heat in our atmosphere and increasing global temperatures via the greenhouse effect.
Intensive farms also use fertilizers which release the powerful greenhouse gas nitrous oxide when applied to the soil.
It is called "Livestock's Long Shadow," and stated that animal agriculture is responsible for 18 percent of greenhouse gas emissions.
When couples separate, they need more rooms, more electricity and more water, which increases their greenhouse gas emissions, he said.
This opens the door to quantifying greenhouse gas emissionsmade from a variety of natural and man-made sources.
The vegetation overwhelmed by the rising waters decays to form methane-a far worse greenhouse gas than carbon dioxide.
He hopes to prod utilities and manufacturers into switching from coal to natural gas, which emits half the amount of greenhouse gases.
As well as the noise, traffic, loss of arable land and threat to birds, airports are a major source of pollution and greenhouse gas emissions.
Targets include increasing the renewable share of energy output to 20% by 2020, and ensuring that 10% of annual greenhouse gas emissions are "sequestered by forests" before 2030.
A study published in the Journal of the American Medical Association estimates that America's health-care industry accounts for 8% of the country's greenhouse gas emissions.
Japan's prime minister promised a 25 percent cut in greenhouse gas emissions from 1990 levels by 2020, laying down a marker for other industrialized nations.
The gas at the centre of the controversy is HFC-23, a greenhouse gas which, on a weight-for-weight basis, is 14, 800 times better at trapping heat than carbon dioxide.
And the cause is clear, say the authors: 'It is very likely that [man-made] greenhouse gas increases caused most of the average temperature increases since the mid-20th century,' says the report.
The other two gases have significantly less impact: isoflurane is only a third as powerful a greenhouse gas as is desflurane and sevoflurane has only an eighth of desflurane's effect.
China had sought more than 10 amendments to the draft summary of the IPCC's report, saying it would cost more and be much harder to reduce greenhouse gas emissions than detailed.
However, the UN secretary general, Ban Ki-moon, said today that a delay of a year before a legally binding treaty was signed would be too long, given the threat posed by greenhouse gas emissions.
The first 14-foot test unit produced enough energy to supply 150 average European homes and saved the emission of over 450 tons of CO 2 greenhouse gas each year.
They are greenhouse gases.
No greenhouse gases would be released.
But he has no serious plan to reduce greenhouse gases.
In this respect, clouds are like greenhouse gases.
Wool and cotton fabrics have a really high greenhouse gasimpact.
We need to see EPA regulation of greenhouse gases immediately and we need to see aggressive regulation of greenhouse gases.
And these greenhouse gases perturb the radiation balance of climate.
Although eruptions do emit greenhouse gases such as carbon dioxide, volcanoes also spew sulfur dioxide.
But coal plants have an additional strike against them: they emit harmful greenhouse gases.
These reflect sunlight away from Earth and thus oppose the effect of greenhouse gases.
One is an economic tool which puts a price on emitting greenhouse gases.
Lava injected into deep sea sediments is baking sediments and driving out greenhouse gases.
Most of the excess heat trapped by greenhouse gasses like carbon dioxide ends up in the oceans.
In a surprise finding, undersea hot lava is baking ocean sediments and releasing greenhouse gases. By Larry o 'hanlon.
Worse, carbon dioxide and water vapor (the two main greenhouse gases) absorb and scatter differently at different wavelengths.
He has moved unilaterally to limit greenhouse gases from vehicles and large sources such as coal-burning power plants.
Such weather doesn't seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases.
CERs are generated by the Kyoto protocol's "Clean Development Mechanism", whereby reductions in greenhouse gases in developing countries can produce a carbon credit for use in industrialised markets.
