Pollutant emissions in the Texas-Mexico border were investigated using an emission database that covers 25 Texas counties and the states of Coahuila, Chihuahua, Nuevo Leon and Tamaulipas in Mexico. Major emissions are from energy generation, mainly from two coal-fired facilities in Coahuila, which also generate most of carbon dioxide. Texas exhibits a larger concentration of sources; around ...
Managers at Alcoa's aluminum container manufacturing facility located near Knoxville, were preparing for revisions to the formula that regulators use to establish air emission fees under Title V of the Clean Air Act. Since Alcoa, a worldwide leader in the production of aluminum sheet for packaging, is well known for its commitment to 'relentlessly pursue and continually improve EHS systems and ...
The new version of the Atmospheric Dispersion Modelling System for urban environments, ADMS-Urban, is based on the same up-to-date physics as the ADMS model, outlined briefly here in Section 2. The basic model has been the subject of extensive validation studies: as part of this series of European Harmonisation Workshops; sponsored by HMIP (Her Majesty's Inspectorate of Pollution, now part of the ...
Ljubljana has an unfavourable geographical location in the basin, almost entirely surrounded by high hills. Winds in the basin are often weak and situations with temperature inversion are very frequent, therefore, many PM 10 daily limit value exceedances were observed in 2011. The Directive 2008/50/EC (EU, 2008) requires member states to adjust or provide new air quality plans in order to ...
The main features and functionality of the urban air quality version of ADMS (ADMS-Urban) have been presented at previous Harmonisation Workshops. The system has now been set up and applied to air quality management, decision support and air quality forecasting in a number of major cities in Europe and beyond, including London. Key recent developments of the system include a regional chemistry ...

The SILAM model with built–in isoprene and monoterpene emission module from natural sources was run for May to August 2006 in Baltic Sea region. In this study VOCs were advected as passive tracers. Modelled hourly VOC–tracer concentrations were compared with sub–half–micrometre aerosol concentrations, simultaneously measured in Preila (Lithuania), Tahkuse (Estonia), Hyytiälä (southern Finland) ...
After carbon dioxide (CO2), methane (CH4) has the largest global impact on greenhouse gases. The global fossil fuel industry is contributing to the total atmospheric methane, but how much and how do the emission trends really look like? Researchers have built the biggest database of global methane emissions so far and found that emissions from gas, oil and coal production are up to 60% higher ...
For documentation, analysis and application of the state of the art and its development in environmental technologies, an information system should be conceived by using modern information and communication techniques. Within this project the pilot phase is being carried out, in which in co-operation with the established working party (industry, host and authorities) a test data bank is being ...
ADMS and ADMS-Urban are new generation air quality models that are easy to use and attractively presented. They run on a PC under Windows and are suitable for modelling of industrial and urban dispersion problems for comparison with limits, planning, and 'what if' scenarios. Each model can be linked to a GIS (geographical information system) for simple entry of sources and clear presentation of ...
Enterprise carbon accounting (ECA) is an essential requirement for companies and will likely become necessary due to government legislation. No longer is it permissible for a company to look within its borders, but it must look at its overall environmental responsibilities and accurately gauge and measure carbon production and emission caused by its very existence. Financial data must be directly ...
The Cement Sustainability Initiative's (CSI) “Climate Actions” publication details the results of industry efforts to address major sustainability challenges. These include: a sector-specific CO2 Accounting and Reporting Protocol, a global database of cement plant energy and emissions performance, a new approach to the Clean Development Mechanism, and ways in which the cement industry could be a ...
The study identifies and estimates the (least) costs and benefits of meeting ambient air quality standards (different sets of limit/target values) for tropospheric ozone in the EU, taking into account deposition constraints for acidification. This report is divided into three parts: Part A describes the methodology of the analysis and reviews the databases used for the scenario calculations. ...
The People's Republic of China (PRC) has been experiencing rapid economic and industrial growth with associated increased air pollution. Government officials strive to improve air quality while maintaining growth. Implemented control measures have not achieved air quality goals; therefore, the Beijing Municipal Environmental Protection Bureau turned to air quality models to help identify sources ...
We have developed an LCA database based on the latest Input-Output (IO) tables for Japan, which were released in 2004. One of the features of this database is hybrid analysis. The ten main imported commodities have been evaluated by the process analysis method and added to environmental burdens inside Japan, calculated based on the Japanese IO tables. In this database, 30 types of inventory have ...
EU GHG inventory submission to UNFCCC (EEA and DG Climate Action) The European Union (EU), as a party to the United Nations Framework Convention on Climate Change (UNFCCC), reports annually on greenhouse gas (GHG) inventories for the years 1990 to X-2 (i.e. two years before the current year1) and within the area covered by its Member States. The legal basis for the compilation of the EU GHG ...
In this report, the European Environment Agency (EEA) presents updated estimates of the external costs (1) of air pollution for different categories of heavy goods vehicles (HGVs). This report on road transport is a continuation of previous reporting from EEA on estimates for the external costs of air pollution from industrial facilities (EEA, 2011). The amended Eurovignette Directive ...
