  • Tracking clean energy progress

    Each year, the IEA’s Tracking Clean Energy Progress (TCEP) report examines developments across a range of clean energy sectors and technologies. The TCEP uses benchmarks for 2025 as modelled in Energy Technology Perspectives 2017, as well as the milestones identified in the IEA Technology Roadmaps. Measuring against these benchmarks provides an assessment of whether technologies, energy ...

  • Dry Air Scrubber for Propylene Oxide

    Background For decades, Advanced Air Technologies, Inc. has been the leader in air scrubber  technology for abatement of Ethylene Oxide (EtO) emissions.   In fact, AAT, Inc. was founded in 1987 on a unique dry scrubbing, chemi-sorption process for EtO.  The result is a series of fixed bed “Safe-Cell II” dry scrubbers, consisting of the DR-490, DR-50, and ...

  • Modeling global emissions and residues of pesticides

    A major portion of persistent organic pollutants (POPs) is organochlorine pesticides (OCPs), in which carbon and chlorine are combined. During the last decade, a number of researches have been devoted to create emission inventories of OCPs at regional and global scales. The studies on residue inventories of OCPs, however, are sparse. In the absence of complete data and information on worldwide ...

  • Modeling emissions from offshore drilling

    To regulate drilling activities proposed by oil and gas companies in the oil-rich Gulf of Mexico (GOM), governing agencies require the submittal and approval of certain plan documents before drilling activities can be initiated. For drilling activities in the Western GOM, these plans typically consist of one of the following: EP, or Exploration Plan – required to conduct ...

  • NO x emission model of turbofan engine

    During last decade a lot of investigations also focused on the evaluation of aircraft engine impact on local and regional air quality in the vicinity of the airport. The emission inventory of aircraft engines are usually calculated on the basis of certificated emission indexes, which is provided by the engine manufacturer and reported in the database of ICAO. The certificated emission indices ...

  • Static and dynamic instantaneous emission modelling

    Emission models can be categorised into three categories: average speed models; traffic situation models, used at macro-scale or meso-scale level (national, regional, city level); and instantaneous (modal) models, useful at micro-scale level (street, vehicle level). To improve the existing instantaneous emission models, some preconditions must be fulfilled: the emission signals should be measured ...

  • Modelling an international market of CO2 emission permits

    Many regions, e.g. countries, have developed energy-economy models (such as MARKAL-MACRO, MM) to assess their energy policies, in particular concerning the curbing of their carbon dioxide CO2) emissions. To integrate regional MM models, we propose a multiregional MARKAL-MACRO (mMM) model. It enables one to study international cooperation to curb jointly CO2 emissions through a market of emission ...

  • Models and muddles: the cost of meeting emission targets

    In 1990, the Australian Government adopted an interim target of reducing greenhouse gas emissions by 20%, subject to it not adversely affecting Australia's trade competitiveness in the absence of similar action by other competitor countries. Since then, a series of reports have attempted to assess the economic effects on Australia of reducing emissions. This paper reviews these reports and ...

  • Magnetic-emission model of catalytic fuel oxidation

    In the following paper, the magnetic-emission model of catalytic fuel oxidation is described. On the basis of this model, the process of methane oxidation of catalytic surface is considered, and the method of efficient adsorption of catalytic radiation is presented.Keywords: catalytic surface, catalytic fuel combustion, magnetic-emission model, catalytic radiation, efficient adsorption, catalytic ...

  • RoadAir - Road network emission and dispersion model

    Traffic is the main source of air pollution in many urban areas. RoadAir is a computerized planning tool for calculating emissions and concentrations of air ...

  • Emission predictions with a multi-linear reservoir model

    ABSTRACTFor the assessment of combined sewer overflows detailed models are not necessary. Physically based conceptual models give an optimal balance between model uncertainty and uncertainty in the input data. Besides, it is important that continuous long term simulations are performed. To prove this, in this paper the calibration of a reservoir model is discussed. The emission results of the ...

  • Modelling emission, concentration and deposition of sodium for Poland

    The aim of this paper was to calculate natural and anthropogenic emission of Na+ and to estimate, with the FRAME model, annual air concentration and deposition of Na+ for the domain covering Poland. Calculations of natural emissions included marine emission and wind blown dust from land. Anthropogenic emission was calculated for both ...

  • Sensitivity of AERMOD in Modeling Fugitive Dust Emission Sources

    Dispersion modelers have long faced challenges estimating ambient pollutant concentrations caused by releases from “fugitive” sources of particulate matter, such as paved and unpaved roadways, raw material storage piles, outdoor material processing operations, agricultural activities, or windblown dust in general. Fugitive emissions are commonly defined as those that could not ...

  • Modelling emissions of perfluorinated chemicals to the Danube River Basin

    The emissions of two perfluoroalkyl acids (PFAAs) into the Danube River Basin have been estimated in a test of four different hypotheses regarding the factors affecting those emissions. The results were used to simulate water concentrations for comparison with measured data. The researchers found that incorporating wastewater treatment information and wealth distribution alongside population data ...

  • 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 ...

  • Interpreting the IPCC emissions scenarios

    This paper discusses how two sets of emissions scenarios, generated using the Atmospheric Stabilization Framework, were used by the United Nations Intergovernmental Panel on Climate Change (IPCC). In particular, it discusses how the scenarios were specified, what roles models played in developing the scenarios, and how the scenarios were interpreted by participants in the IPCC process. It draws ...

  • An end to the problem of particle emissions

    Austrian biomass heating systems guarantee an 80% cut in emissions. Recent studies have shown that these modern domestic boilers offer a significant reduction in particles, emitting fewer contaminating agents than previous generation boilers and wood stoves – with more than 100mg / ml of particles. The future will be based on new biomass combustion technology which cuts dust emissions from ...

  • Carbon emissions - carbon formula

    Carbon emissions represent an increasing and potentially significant cost for business.  The case that carbon measurement and reporting systems can help organisations make significant reductions ...

  • Model analyses of long and short term pollution emission reduction

    Climate change is influenced not only by the emissions of greenhouse gases, but also by the emissions of air pollutants which influence each other through complex interactions in the atmosphere. Reducing emissions could be one way to react and prevent negative impacts from climate change. Because these reductions must take place in the face of economic growth, there is a disagreement about the ...
