of nitrogen oxide emissions from the power sector.
For example, in the US, each time the Clean Air Act has been amended since 1972, fossil - fuel power companies and their associated think - tanks screamed bloody murder that sulfur dioxide and
nitrogen oxide emission reductions would essentially destroy the economy (all but ignoring the obvious health and environmental benefits that did come to fruition).
The policy document also set new targets for the closure of coal - fired heating systems as well as the installation of equipment to reduce sulfur dioxide and
nitrogen oxide emissions at power stations, steel mills and cement plants.
For the past ten years the plant has been operating without the level of emissions controls to limit sulfur dioxide and
nitrogen oxide emissions as stipulated in the Clean Air Act.
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.
Environmental groups and national park advocates had hoped the plan would require Rocky Mountain Power to retrofit two of its biggest Utah plants with the best technology available today for
capturing nitrogen oxide emissions.
The traffic -
related nitrogen oxide emissions in the Federal Republic of Germany have fallen sharply since the introduction of the emission limitation for road traffic in 1960 up until today and a further reduction by a total of 86 % in maximum emissions is expected in the future as well [58].
In 2014, researchers at the National Oceanic and Atmospheric Administration found that the increased use of natural gas combined cycles in power generation has led to 40 percent
less nitrogen oxide emissions and 44 percent less sulfur oxides emissions since 1997.
In 2014, the most recent data available when Connecticut filed an EPA petition over Brunner Island, the Pennsylvania power plant's
nitrogen oxide emissions alone were nearly double those of Connecticut's entire electric power industry, and modeling showed it was a major contributor to Connecticut smog.
They have developed a new way of producing ammonia which reduces
nitrogen oxide emissions by 87 per cent, sulphur dioxide by 95 per cent and carbon dioxide by 60 per cent — and it uses less resources.
1) TCEQ should focus spending on vehicle grants, because the transportation sector is the largest contributor
of nitrogen oxide emissions.
Switching from coal to natural gas would reduce sulfur dioxide emissions by more than 90 percent and
nitrogen oxide emissions by more than 60 percent.
The company «would not be able to give officials «a sound explanation for the dramatically elevated»
nitrogen oxide emissions,» his memo warned, according to the New York Times, and regulators were «likely to investigate whether Volkswagen cars were equipped with «a so - called defeat device.»»
The charge will apply to vehicles that do not meet «Euro 4» standards for particulate matter and
nitrogen oxide emissions.
Another measure, the federal Cross-State Air Pollution Rule, will require still more expensive controls on coal plants in the Midwest and South to reduce sulfur dioxide and
nitrogen oxide emissions that travel across state lines, creating ozone and fine particle pollution downwind.
By simulating how a highly volatile, low - soot fuel behaves in many engine designs, «We hope to retain the performance of diesel fuel with lower particulate matter and
nitrogen oxide emissions,» said Roberto Torelli, an Argonne postdoctoral researcher on Som's team.
If the current trends persist, ammonia emissions will increase by 85 % by 2050;
nitrogen oxide emissions will go up more than eightfold.
A study commissioned by Iridium found that between the service's proposed start in 2017 and 2030, the technology should save airlines about $ 7 billion on fuel and cut carbon dioxide and
nitrogen oxide emissions by 35 million tonnes.
The combined hydrocarbon and
nitrogen oxides emissions were also 76 per cent below the standard the European Commission plans to impose in 1996.
«As now,» says the document «objectives will need to be consistent with national policies for carbon dioxide and
nitrogen oxides emissions.»
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.
The Government estimates that
nitrogen oxide emissions (bought sharply into focus by VW's diesel scandal) and poor air quality in general cost the economy # 2.7 billion in lost productivity each year, calling it «the largest risk to public health in the UK».
Every diesel Tiguan Allspace is outfitted with a twelve - litre AdBlue tank to help reduce
nitrogen oxide emissions.
According to GM, the new Duramax turbo - diesel will boost efficiency by 25 percent, while cutting carbon dioxide emissions by 13 percent and
nitrogen oxide emissions by 90 percent.
To reduce
nitrogen oxide emissions, Mercedes - Benz first uses dual electrically controlled and cooled exhaust gas recirculation (EGR) which, depending on engine operating conditions, redirects up to 40 % of the exhaust gases back into the cylinders.
Most of Volkswagen's diesel competitors opted for urea - injection, using an additive called AdBlue contained in a separate reservoir that helps to reduce
nitrogen oxide emissions.
Toyota says the small gasoline engine emits about 50 percent as much carbon monoxide as a regular car engine, and
nitrogen oxide emissions are 90 percent below the current Japanese regulations.
The US EPA says that a buffer that could be in place by next year could «save 8,000 lives a year with new air quality standards cutting sulphur in fuel by 98 %, particulate matter by 85 % and
nitrogen oxide emissions by 80 %.»
