  • US Carbon Emissions Down 7 Percent in 4 Years: Even Bigger Drops Coming

    Between 2007 and 2011, carbon emissions from coal use in the United States dropped 10 percent. During the same period, emissions from oil use dropped 11 percent. In contrast, carbon emissions from natural gas use increased by 6 percent. The net effect of these trends was that U.S. carbon emissions dropped 7 percent in four years. And this is only the beginning. Graph on U.S. Energy-Related ...

  • In-situ continuous emissions monitoring & regulatory compliance

    As environmental scrutiny has risen and regulation has tightened in recent years, the importance of having accurate information on the environmental performance of your power plant has increased. After all, if you want to manage something, you need to be able to measure it. The analogy is obvious; you wouldn't start a diet without first investing in a set of scales. So it is with Continuous ...

  • School bus retrofits one local air

    The Hamilton County Department of Environmental Services, a local air agency covering the Greater Cincinnati Area in Southwest Ohio, has experienced many successes and failures obtaining grant money to fund school bus retrofits. However, seven years of persistent work has paid-off enormously. The adverse health effects of diesel exhaust were making national headlines in the early 2000s. The U.S. ...

  • Greenhouse gas emissions from the production and use of palm methyl ester in Thailand

    This study compares the life cycle Greenhouse Gas (GHG) emissions from Palm Methyl Ester (PME) and conventional diesel (diesel hereinafter) used for transportation in Thailand. The life cycle GHG emissions from the production and use of PME were found to be 79.5% less than that from diesel production and use. Hence, a fuel switch from diesel to PME, according to the Thai government's plan of ...

  • Composition and textural properties of soot and study of their oxidative elimination by catalytic process

    Diesel soot and reference carbon black samples have been characterised by analysis of the organic compounds fraction and determination of textural characteristics (specific area). The potential to eliminate such carbonaceous particles has been investigated using a Cu/ZrO2 solid catalyst promoted by potassium additives. The reactivity of soot samples depends on the organic compounds content. In ...

  • The emission characteristics of a compression ignition engine operating on castor oil methyl ester

    Diesel vehicles are a major form of transportation, especially in developing countries. Recent concerns over the environment, increasing fuel prices and the scarcity of its supply have promoted interest in the development of alternative sources of petroleum fuels. In this investigation, castor oil methyl ester was prepared by transesterification using potassium hydroxide (KOH) as a catalyst and ...

  • The high cost of health, environment, and worker impacts of the Oakland port trucking system

    As the fifth largest container port in the United States, the Port of Oakland is an important hub for the movement of consumer goods in and out of the region, California, and the country. The regional economic benefits of the Port include trade and logistics transactions, business taxes and revenues, and job creation. However, the economic benefits of the Port are not shared equally among ...

  • Real-world vehicle emissions

    The Coordinating Research Council (CRC) convened its 18th On-Road Vehicle Emissions Workshop March 31–April 2, 2008, with 104 presentations describing the most recent mobile source-related emissions research. In this paper we summarize the presentations from researchers whose efforts are improving our understanding of the contribution of mobile sources to air quality. Participants in the workshop ...

  • Low emission combustion of Oilgas

    Type     HOFGAS®- IFM4c/2300/150 Commissioning     June 2001 Site     Cistierna (ES) Situation Enervisa SA in Cistierna own a plant for the recycling of old oils. The oil is evaporated and condensed into high-grade fuel. The reclaimed fuel is used in diesel engines for production of electricity as well as in burners for the ...

  • CO2 benefit from the increasing percentage of diesel passenger cars in Switzerland

    One efficient way to decrease CO2 emissions is to replace gasoline passenger cars by diesel cars. The paper examines the benefit of CO2 emissions in the case of an increased diesel penetration in Switzerland, according to several scenarios assuming different future passenger car registrations and fuel consumption. The results show that a significant CO2 benefit can be achieved if a diesel ...

  • Reaching Euro VI emissions limits

    The requirements of low and lowest detectable exhaust analysis has prompted Eco Physics to launch a broad range of analyzers for NO/NOx detection. Emissions tuning is one of the targets of the EURO VI regulations as well as US EPA 2010, which are: Reduction of Particulate Matter (PM) and reduction of Nitrogen Oxides (NOx). In the past 15 years – since the first European regulation for exhaust ...

  • A quantitative approach to the traffic air quality problem: the traffic air quality index

    The Traffic Air Quality (TAQ) model is a simple tool to estimate traffic fine particulate emissions on roadways (g/km) and can be used for both real-time analysis and for localized conformity analysis (“hot-spot” analysis for nonattainment areas) as defined by 40 CFR 93.123. This paper is a follow-up to a study published earlier regarding the development of the TAQ model. This paper shows how ...

  • Hybrid electric vehicles today

    There are quite a range of hybrid Electric vehicles on the market today such as the Toyota Prius, Honda Insight,Honda Civic, Toyota Camry, Toyota Highlander and Ford Escape. The Prius is manufactured at a volume of about 5000 per month, and Toyota recently announced that it is making a modest profit on these cars. The cost of HEVs is about $5000 more than comparable conventional vehicles, and ...
