Sentences with phrase «based nitrogen emissions»

Not exact matches

Global agricultural emissions of the gas have increased by 20 per cent in the last century as a result of widespread use of nitrogen - based synthetic fertilizers.

When hydrocarbon - based fuels like methane are burned in normal air, nitrogen gets mixed in with the combustion product — flue gases from conventional gas power stations contain as little as 3 percent CO2 — which makes scrubbing carbon from power plant emissions difficult and expensive.

A leader in this quest is German - based automaker DaimlerChrysler, which recently introduced BLUETEC technology — a modular exhaust treatment system that cuts nitrogen oxide and soot output significantly, enabling cars to meet the most stringent U.S. emission standards.

-- For a covered entity described in section 700 (13)(C), 1 emission allowance for each ton of carbon dioxide equivalent of fossil fuel - based carbon dioxide, nitrous oxide, or any other fluorinated gas that is a greenhouse gas (except for nitrogen trifluoride), or any combination thereof, produced or imported by such covered entity during the previous calendar year for sale or distribution in interstate commerce.

Nitrous oxide emissions are primarily from nitrogen - based fertilizers used for soil management.

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 DC Circuit today struck down EPA's Cross State Air Pollution Rule (CSAPR), the EPA's latest attempt to regulate sulfur dioxide and nitrogen oxide emissions from power plants, using at least somewhat flexible, market - based tools.

Hitting SunShot goals is also found to reduce sulfur, nitrogen, and particulate emissions, delivering $ 167 billion in health and environmental benefits, or 1.4 cents per kWh of solar, again based on central estimates.

Human emissions of reactive sulfur and nitrogen, derived from fossil fuel combustion and agriculture, have led to increased deposition of strong acids (HNO3 and H2SO4) and bases (NH3) to the ocean, hence affecting seawater pH (Doney et al. 2007).

The move toward Tier 4 is made up of a 45 percent reduction in the oxides of nitrogen emissions compared to the current Tier 2 standard and an 85 percent reduction in particulate matter emissions based on preliminary analysis.
