London road traffic NOx emissions still below 50% of pre-COVID-19 levels
CERC continues to run its inverse modelling system (details in our April News item) to determine NOx emissions in London as easing of the lockdown progresses. The latest model calculations up to July 17 show that whilst there has recently been some increase in emissions, they typically remain below 50% of the pre-COVID values. Consistent with this, London road traffic NOx emissions for our ...

Cap and trade program lowers smog levels in eastern united states
EPA released a report showing that more than 103 million Americans breathe cleaner air thanks to a cap and trade program that reduces smog-forming emission of Nitrogen Oxides (NOx). The 2008 NOx Budget Trading Program Annual Report, covering 20 eastern states and the District of Columbia, shows the summertime NOx emissions from power plants and large industrial sources were down by 62 percent ...

Reducing NOx emissions for a Cleaner Environment
Selective Catalytic Reduction (SCR) is one of the most popular processes today to reduce the emission of nitrogen oxides (NOx) from combustion sources, such as power plants, stationary power stations, ship engines or even automobiles. Axetris LGD F200 OEM Modules for ammonia (NH3) detection are being successfully used today to control and test the process of urea injection for NOx reduction. ...

EU states expect to exceed air pollutant limits
The European Environment Agency has confirmed that 11 EU countries expect to exceed their legal emissions ceiling for nitrogen oxides (NOx) in 2010, some by more than 40%. The EEA's annual status report reveals that several Member States, including Slovenia, Sweden and the United Kingdom, expect to exceed their respective NOx ceilings by small margins (less than 5 %). However, France and Spain ...

NOx road transport measures in Europe have been effective
Policies introduced across Europe to reduce the emission of nitrogen oxides (NOx) from road transport have been effective, despite an increase in vehicle fuel consumption between 1990 and 2005, according to a new study. Man-made nitrogen oxides (NOx), including nitric oxide (NO) and nitrogen dioxide (NO2) emissions are air pollutants which affect climate change, human health and ecosystems. ...

Health professional societies send joint statement on diesel NOx emissions to members of German Parliament
Together with three health professionals societies the Health and Environment Alliance (HEAL) has sent a statement to members of the German Parliament on evaluating health risks from diesel NOx emissions, on the occasion of a parliamentary report on the subject. The European Respiratory Society’s (ERS) Environment and Health Committee, the International Society for Environmental ...

EPA Report: Smog Thinner, Skies Healthier over Eastern U.S.
(Washington, D.C. - Sept. 27, 2007) Smog-forming emissions of nitrogen oxides (NOx) from power plants and industry have declined significantly in 19 eastern states and the District of Columbia. The NOx Budget Trading Program (NBP) annual report, released today, indicates that summertime NOx emissions were seven percent lower than in 2005, 60 percent lower than in 2000 and 74 percent lower than in ...

IMO U-turn jeopardises citizens` health in EU Year of Air
The International Maritime Organisation (IMO) today decided to postpone the entry into force of nitrogen oxide (NOx) emissions limits for ship engines from 2016 to 2021. Environmental NGOs Transport & Environment (T&E) and Seas at Risk, founding members of the IMO observer organisation Clean Shipping Coalition, condemn IMO’s decision and now call on the EU to adopt its own NOx ...

EPA to hold two public hearings on proposed pollution controls at Reid Gardner Generating Station
The EPA recently proposed to limit nitrogen oxide (NOx) emissions at Reid Gardner Generating Station in Moapa Valley, Nevada, as part of a national effort to reduce regional haze that impairs visibility at protected national parks and wilderness areas. The proposal published on April 12, 2012 would establish lower limits for NOx emissions under Federal and state plans that require the facility to ...

High NOx Emissions from Diesel Cars
It is time to sell your diesel car. In a few years you will not be able to use it in a city. The real drive emissions measurements from passenger cars are giving astonishing results. A new diesel car has 10 times higher NOx emissions compared to a petrol car. Even worse, the NOx emitted from the diesel car is up to 50% emitted as NO2. The NOx emitted from a petrol car is only a few % emitted as ...

High potential to cut air pollution from Europe`s power plants
Emissions of nitrogen oxides (NOx) and sulphur dioxide (SO2) from large combustion plants (LCP) could have been considerably lower in 2004, a report presented today by the European Environment Agency says. Power plants burning coal, oil and/or gas are significant contributors to European emissions of NOx and SO2 — two important acidifying pollutants. Improving the environmental performance of ...

Travelling slower reduces fuel consumption and nitrogen oxides emissions of ships
Ships that reduce their speed use less fuel, which lowers costs for shipping companies. The slow steaming practice also cuts nitrogen oxides (NOx) emissions. A study found that ships travelling on four European routes lowered their NOx emissions by 12% during the economic crisis of 2008/2009. Shipping continues to be a major way of transporting goods, however, and as the global economy recovers ...

Nitric Acid Plants: Proposed NSPS Revisions
PROPOSED REVISIONS TO NEW SOURCE PERFORMANCE STANDARDS (NSPS) FOR NITRIC ACID PLANTS On September 30, 2011, the U.S. Environmental Protection Agency (EPA) proposed to strengthen air pollution limits for nitric acid plants. Most nitric acid is used to produce fertilizer. The proposed standards, known as New Source Performance Standards (NSPS), would limit emissions of nitrogen oxides (NOx) ...

Breathing easier: Cap and trade lowers smog levels in eastern United States
More than 102 million Americans are breathing cleaner air due to decreases in smog-forming emissions of nitrogen oxides (NOx) according to the NOx Budget Trading Program annual report. The 2007 summertime NOx emissions from power plants and industrial sources were down by 60 percent compared to 2000 levels and 74 percent below 1990 levels in 20 eastern states and the District of Columbia.

MEPs throw ship NOx monitoring overboard
MEPs voted Wednesday April 16,2014 to reject a proposal to monitor nitrogen oxides (NOx) emissions from shipping, which is set to overtake all land-based sources by 2020. Transport & Environment says EU governments must not waste this unique opportunity to monitor two of the most harmful air pollutants, NOx and sulphur (SOx), as part of the monitoring, reporting and verification (MRV) of ...
