Sentences with phrase «oxide emissions when»

The lawsuit claims that Allegheny undertook many construction projects over the years to extend the operational lifespan of these plants without complying with federal standards that require implementation of best available control technology standards to reduce sulfur dioxide and nitrogen oxide emissions when new sources of power are constructed.

Not exact matches

As the world began to learn in September, when the U.S. Environmental Protection Agency issued a shocking «notice of violation,» the vehicles met emissions standards for dangerous oxides of nitrogen, known collectively as NOx, only when running their paces in an artificial, indoor lab setting.

Concerns over the Dreamliner kicked off over a decade ago when Boeing decided to create a civil airliner that would be both lighter than any of its previous jets and fly with leaner - burning engines to cut the plane's emissions of CO2 and nitrogen oxides.

According to the U.S. Environmental Protection Agency, the process of manufacturing glass not only contributes its share of greenhouse gas emissions but also generates nitrogen oxides, sulfur dioxide and tiny particulates that can damage lung tissue when breathed in.

And a new study shows that biochar could have an impact on agriculture's other greenhouse gas emission: nitrous oxide, or laughing gas, which is no laughing matter when it comes to climate change.

Food production accounts for a third of all greenhouse gas emissions when one tallies those from fossil fuels used in growing, preparing and transporting food; the carbon dioxide released by clearing land for farming and pastures; the methane from rice paddies and ruminant livestock; and the nitrous oxide from fertilizer use.

But the courts haven't always struck down EPA emissions trading programs — such as the trading program for nitrogen oxides — and when they have disqualified programs, it was either because agencies failed to follow proper procedure (as was the case with a Bush - era mercury rule that eased requirements on power plants) or because specific statutory goals were not followed (as was the case in the Clean Air Interstate Rule, which wouldn't have necessarily reduced all interstate pollution).

The sales ban is part of a wider move to tackle air quality in the UK — a hot topic, particularly when it comes to nitrogen oxide emissions.

When spring thaw emissions were combined with growing season emissions, the conventional tillage system actually had higher total nitrous oxide emissions than the zero till system.We suggest that this type of experiment (full year emission measurements) be repeated with deep banding of N fertilizer, which would be expected to further reduce emissions from zero till systems.

While these forgotten gases account for only a small fraction of total greenhouse gas emissions from deforestation, nitrous oxide is up to 300 times more effective at trapping heat in the atmosphere when compared to carbon dioxide over a 100 - year time period.

Thus experiments are needed to measure nitrous oxide emissions even when data is available on N fertilizer efficiency for various N fertilizer sources and methods of placement.

When coal is burned due to combustion that is more or less completed the result is different levels of energy (B.T.U.'s), and different levels of air emissions (Sulfur Dioxide - SO2, Mercury - Hg), greenhouse gases (Carbon Dioxide CO2, Nitrogen Oxide - NO3), and amounts of ash that can potentially be toxic dependent on the conditions within the combustion chamber and ash that can or can not be used in a secondary market (ex.

But it's also the by - product of fossil fuel combustion, and when a refinery or power plant reduces its greenhouse gas emissions (by becoming more energy - efficient, for example), it also releases fewer smog - forming chemicals like nitrogen oxides, less of the sulfur dioxide and soot that can irritate lungs and cause respiratory disease, and fewer toxic emissions linked to cancer and neurological disorders.

Aircraft not only emit 12 percent of CO2 emissions from U.S. transportation sources — they also emit nitrogen oxides other than nitrous oxide, causing warming when emitted at high elevation.

When compared with pure electric vehicles that use coal - generated electricity, H600's emission of sulfide, nitrogen oxide, and particle matter is 0.17 %; 0.67 %; and 50 % of the latter, respectively (a typical coal power plant emits 272 grams of PM when generating one kWh of electriciWhen compared with pure electric vehicles that use coal - generated electricity, H600's emission of sulfide, nitrogen oxide, and particle matter is 0.17 %; 0.67 %; and 50 % of the latter, respectively (a typical coal power plant emits 272 grams of PM when generating one kWh of electriciwhen generating one kWh of electricity).

When you allow for emissions of methane, CFCs, ozone, nitrous oxide and soot — which also warm the atmosphere — the carbon dioxide budget is an even tighter 3,200 billion tonnes, note Pierre Friedlingstein and colleagues in the paper.

95 The case for crop - based biofuels was further undermined when a team led by Paul Crutzen, a Nobel Prize — winning chemist at the Max Planck Institute for Chemistry in Germany, concluded that emissions of nitrous oxide, a potent greenhouse gas, from the synthetic nitrogen fertilizer used to grow crops such as corn and rapeseed for biofuel production can negate any net reductions of CO2 emissions from replacing fossil fuels with biofuels, thus making biofuels a threat to climate stability.

The earliest sulfur dioxide and nitrogen oxides data I have for those two plants is from 1984 when the sulfur dioxide emission rate was 2.04 lbs of SO2 per mmBtu and the nitrogen oxide emission rate was 0.56 lbs of NOx per mmBtu.

When I retired in 2010, the sulfur dioxide emission rate was 0.527 lbs of SO2 per mmBtu (81 % reduction) and the nitrogen oxide emission rate was 0.159 lbs of NOx per mmBtu (73 % reduction).

Surprisingly, the research finds that when it comes to these human - driven methane and nitrous oxide emissions, a key driver is Southern Asia, and rice cultivation in particular.
