Analysis of point source emissions in the Texas-Mexico border region
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 ...

ADMS-Urban: an air quality management system for traffic, domestic and industrial pollution
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 ...

Determinating the influence of different PM 10 sources on air quality in Ljubljana basin with CALPUFF dispersion model
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 ...

Determination of compliance with UK and EU air quality objectives from high-resolution pollutant concentration maps calculated using ADMS-Urban
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 ...

Methane emissions higher than estimated
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 ...

Atmospheric transport model applied to understand the effect of biogenic emissions to secondary atmospheric aerosol in hemiboreal zone
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) ...

Conception of an environmental technology data bank
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 ...

2012 sees slowdown in the increase in global CO2 emissions
Actual global emissions of carbon dioxide (CO2) reached a new record of 34.5 billion tonnes in 2012. Yet, the increase in global CO2 emissions in that year slowed down to 1.1% , which was less than half the average annual increase of 2.9% over the last decade. This is remarkable, as the global economy grew by 3.5%. This development signals a shift towards less fossil-fuel-intensive activities, ...

ADMS and ADMS-Urban
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 ...

Global growth in CO2 emissions almost stalled in 2014
In 2014, the growth in global CO2 emissions from fossil fuel use and cement production slowed down to only 0.5% compared to 2013, while the world’s economy grew by 3%, showing a partial decoupling of CO2 emissions and economic growth. China and the United States increased their emissions by 0.9%. In the European Union, CO2 emissions decreased by an unprecedented 5.4%, while India’s ...

Climate actions
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 ...

Economic Evaluation of Air Quality Targets for Tropospheric Ozone
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. ...

Development of comprehensive LCA database based on input-output tables
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 ...

The Air Quality Management Decision Support System (AQMDSS) for Beijing, People's Republic of China
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 ...

Enterprise Carbon Accounting: The quest for unprecedented transparency
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 ...
