  • Air traffic management to balance CO2 emissions and noise pollution

    Speed constraints for aircraft are put in place, at some airports, to minimise noise pollution in local areas, however, such practices can be very fuel-inefficient. New research has now shown that relaxing departure speed limits could substantially reduce CO2 emissions, while maintaining acceptable noise levels. The aviation industry is a major contributor to emissions of greenhouse ...

  • Childhood obesity linked to traffic pollution

    Traffic pollution contributes to childhood obesity, a recent study concludes. In the US investigation of over 4 500 children, the researchers estimated that air pollution increased the body mass index (BMI) of 10-year olds in the most polluted areas of study by 0.4 units, compared to those in the least polluted areas. It is thought that pollution may have slowed the children’s metabolism. ...

  • CARBOTRAF – Black Carbon reduction by traffic management

    CARBOTRAF is a Seventh Framework Programme (FP7) of the European Commission. Lasting for three years, the project will study the relationship between traffic flow, Black Carbon (BC) emissions and carbon dioxide in urban environments. The project aims to create a method, system and tools for adaptively influencing traffic flow in real-time to reduce CO2 and BC emissions caused by road ...

  • Traffic pollution hotspots to be revealed ‘live’ in London

    A pioneering network of sensors could make the traffic build-ups that cause pollution hotspots a thing of the past. The ‘Pioneers 09’ showcase event on March 4th will be the first time that real-time data from the network has gone on public display. ‘Pioneers 09’ is being held at the Olympia Conference Centre in London and organised by the Engineering and Physical Sciences Research Council ...

  • Traffic pollution associated with risk of developing type 2 diabetes

    Long-term exposure to traffic-related air particle pollution is linked with type 2 diabetes, a new study in Germany has found. Furthermore, the study found that people living close to busy roads were at greater risk of developing the disease than those living further away. Air pollution has been linked to a number of health problems, including heart, circulatory and lung diseases. It has also ...

  • Air pollution from road traffic can raise blood pressure

    High blood pressure is linked to long-term exposure to traffic-related air pollution, new research suggests. After accounting for lifestyle factors, socioeconomic status and pre-existing health conditions, the researchers found that a rise in traffic emissions of nitrogen dioxide corresponded to a rise in blood pressure of exposed individuals. Long-term exposure to air pollution has previously ...

  • Modelling marine exhaust emissions in the Baltic Sea

    A new tool used to investigate exhaust emissions of marine vessels has been developed and applied to shipping in the Baltic Sea. The Baltic Sea is a busy maritime region with 3500-5000 ships operating in the area every month. Emissions from shipping contribute significantly to atmospheric pollution, leading to health and environmental problems. In May 2006, the Baltic Sea was the first area ...

  • Calculating emissions from shipping

    Shipping is a significant source of atmospheric pollutants, which contribute to climate change and have negative effects on human health and the environment. A new study has applied detailed methods to estimate global fuel consumption from international shipping, including for the first time, an estimation of emissions from the global fleet while in port. Developing appropriate policies to ...

  • CarCharging Receives $200,000 NYSERDA Award to Install Electric Vehicle Charging Stations in 15 High-Traffic Locations in New York

    CarCharging Group (OTCBB: CCGI), a leading provider of electric vehicle (EV) charging services, today announced it received funding from the New York State Energy Research and Development Authority (NYSERDA) to supply, deploy and install EV charging stations throughout New York City. Powered by the ChargePoint® Network, the CarCharging EV charging stations will be installed in ...

  • Stricter low emission zone in Berlin

    Berlin has established an Low Emission Zone (Environmental Zone) for the City centre on January 1st 2008. Its purpose is to reduce harmful pollutants in the air that are caused by road traffic. From January 1st 2010 on, only cars with green stickers will be allowed to enter the zone. More information on Berlin’s Environmental Zone: ...

  • Impact of transport emissions on the lower atmosphere

    Traffic emissions cause a number of damaging chemical changes in the atmosphere. A recent study has estimated the impact of road, aircraft and ship emissions on the atmosphere's chemical make-up in terms of ozone and the hydroxyl radical OH. Traffic emissions form a large part of EU air pollution and are the subject of climate change policy1. Ozone pollution in the troposphere adversely affects ...

  • New Energy`s MotionPower(TM) System for Generating Sustainable Electricity From Moving Cars to Debut at High-Traffic Complex in Virginia

    New Energy Technologies, Inc. (OTCQB: NENE) (PINKSHEETS: NENE) today announced that the Company's latest MotionPower?-Express system, capable of generating sustainable electricity from moving vehicles, will debut at a high-traffic volume convention, exhibition and cultural center in the Virginia this month. "We conducted early field tests of MotionPower? at Burger King®, the Four Seasons ...

  • Mobile monitoring station assesses diesel emissions

    Researchers in Greece are using a Gasmet FTIR multiparameter gas analyzer, deployed in a mobile van (MOBILAB), to undertake exhaust gas analysis for comparison with ambient air quality data. “This enables us to undertake temporal and spatial air quality measurements from within traffic, measuring emissions during different traffic conditions,” says Apostolos Tsakis, from the Aerosol ...

  • Mapping greenhouse gas emissions at street level

    Arizona State University researchers have developed a new software system capable of estimating greenhouse gas emissions across entire urban landscapes, all the way down to roads and individual buildings. Until now, scientists quantified carbon dioxide CO2 emissions at a much broader level. Dubbed Hestia after the Greek goddess of the hearth and home, researchers presented the new system in an ...

    Original story at MIT News The roadway network is an important part of the nation’s transportation system, but it also contributes heavily to greenhouse gas emissions. A paper published this ...

  • Latest emission control technology could eradicate harmful air pollution hotspots

    Switching to the best available emission control technologies could eliminate 99% of particulate matter pollution ‘hotspots’, a new study suggests. The researchers reached this conclusion by expanding the local-scale capabilities of an existing computer model that estimates the effects of air pollution policies and control measures. Particulate matter (PM) pollution has been linked ...

  • Obama administration finalizes emissions standards for light-duty vehicles

    The Obama Administration announced the finalized historic fuel economy and greenhouse gas emissions standards for light-duty vehicles. The final program for model year 2017-2025 passenger cars and trucks will require an average CO2-level of 163 grams per mile, which is equivalent to 54.5 miles per gallon by 2025, if all reductions are made through fuel-economy improvements. Today’s action ...

  • New emissions certification test for cars could be improved, study concludes

    A test currently under development for certifying levels of vehicle emissions may not adequately represent real world driving conditions, a new study suggests. The authors measured emissions during the new Worldwide Light-Duty Test Cycle (WLTC) compared with those in existing driving cycles and highlighted areas where the test could be potentially improved. In the EU, tailpipe emissions from new ...

  • Shipping emissions can lead to high local ocean acidification

    Strong acids formed from shipping emissions can produce seasonal ‘hot spots’ of ocean acidification, a recent study finds. These hot spots, in ocean areas close to busy shipping lanes, could have negative effects on local marine ecology and commercially farmed seafood species. Oceans have become more acidic since pre-industrial times. The average global ocean pH – which ...
