  • Reduction of the Emissions of HFC`s, PFC`s and SF6 in the European Union

     The report provides a first estimate of the development of the EU-wide use and emissions in 2005 and 2010 of the three industrial halogenated gases included in the Kyoto protocol, namely hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). It also makes a preliminary assessment of the options and costs of controlling these three gases, as well as of the ...

  • Greenhouse Gas Tailoring Rule - The Regulatory Permitting Climate Forecast is Getting Hot

    The EPA is moving forward in regulating Greenhouse Gas emissions and has published the reporting rule and its final rule to control greenhouse gas (GHG) emissions from stationary sources. If you are a major source under the prevention of significant deterioration program or a major source under Title V you will be subject to this rule. ...

  • Use of ejectors in cascade refrigeration systems for exergetic performance improvement

    In this paper an expansion cascade refrigeration system are compared to cascade systems using ejectors. This comparison is made for a variety of fluids. Natural fluids and hydrofluorocarbons (HFCs) are used in the two loops. Theoretical models are written using FORTRAN. The thermodynamic parameters of fluids are given using the software REFPROP 8.0. For fixed working conditions, using CO ...

  • Environmental risks of new–generation fluorocarbons in replacement of potent greenhouse gases

    This article aimed to address two categories of environment friendly fluorocarbons (i.e., hydrofluoroethers and hydrofluoro–olefins), which are used as replacements for potent greenhouse gases like hydrochlorofluorocarbons (HCFC) and hydrofluorocarbons (HFC). In the work, the author will introduce the new–generation fluorocarbons on the basis of their excellent data on the ...

  • Summarizing the fundamentals of fugitive emission tracking

    Fugitive emission tracking for a number of key industries is now a focus for the United States and a number of other countries. When a hazardous leak occurs it is important to identify and gauge the amount and type of substance emitted. Officials will gain a better understanding of the challenge posed by greenhouse gases, as they affect global warming. When an unexpected leak of a hazardous ...

  • EPA plans to make greenhouse gas (GHG) emissions reporting mandatory

    Mandatory carbon (CO2) emissions reporting is more important than ever as the United States works with facilities to reduce substances known to adversely affect air quality, the climate, and lead to global warming. Most of the known matter that is destroying the earth’s ozone layer and contributing to global warming is derived from manmade compounds and chemicals with high global warming ...

  • Ozone-depleting substances 2013

    Aggregated data reported by companies on the import, export, production, destruction and feedstock and process agent use of ozone-depleting substances in the European Union Background The Montreal Protocol on Substances that Deplete the Ozone Layer entered into force in 1989 and aims to protect the stratospheric ozone layer by phasing out more than 200 substances, ...

  • EPA proposes new greenhouse gas emission standard under the Clean Air Act

    The Environmental Protection Agency (EPA) has recently proposed a new GHG emissions program designed to further regulate the amount of greenhouse gas produced in the US. The proposed Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule would require large facilities to obtain operating permits for their greenhouse gas (GHG) emissions. Large facilities are defined as ...

  • Can the U.S. get there from here? Using existing federal laws and state action to reduce greenhouse gas emissions

    U.S. greenhouse gas emissions are expected to rise unless additional policy actions are taken. This report identifies a suite of policies that the Administration can pursue that do not require new legislation by the U.S. Congress. If pursued with “go-getter” level ambition, those policies can reduce U.S. emissions 17 percent below 2005 levels in 2020. Key Findings Without new ...

  • Mandatory Carbon Reporting for London Stock Exchange Listed Companies

    In June 2012 The UK’s Deputy Prime Minister, Nick Clegg announced a new mandatory carbon reporting requirement for all main board companies on the London Stock Exchange (list of 1,370 companies here). This follows a public consultation last year where the majority supported making GHG ...

  • Emission scopes help to categorize greenhouse gas (GHGs) reporting efforts

    Emission scopes are being used to determine the category of chemical and usage area, so that facilities can understand and monitor their greenhouse gas impact. The US Clean Air Act and the Montreal Protocol have established that emissions of harmful substances must be controlled worldwide. When discharged into the air, these chemicals can cause severe damage to the global environment. Three ...

  • How to decifer government laws for refrigerant gases (R-22 HCFCs)

    Refrigerant Gas Regulations for R-22 HCFCs: How the Government Mandates Monitoring and TrackingThe U.S. Clean Air Act is a regulation that spells out the EPA's role in air quality, especially in protecting the ozone layer and the tracking and reporting of Greenhouse Gases. The Act is maintained by the House of Representatives. The Clean Air Act has had changes made in the 1990s and again in 2008 ...

  • Simplified mass balance method: An accurate way to track refrigerant emissions

    With the simplified mass balance method, current levels of harmful refrigerant gases or other chemicals that harm the environment, such as hydrofluorocarbons (HFCs) and chlorofluorocarbons (CHCs), can be calculated and work to better predict of future levels of accumulated emissions formulated. This emissions information enables environmental scientists and government regulators to better ...

  • Recent USEPA Rulings To Reduce GHGs

    Over the last few months the USEPA has begun to implement rules to reduce greenhouse gas (GHG) emissions. Not the traditional way by having affected facilities measure and reduce GHG emissions, but instead by encouraging operational changes to accomplish the same goal. 2 rulings that can affect businesses are discussed here. 1. Alternative refrigerants. This past December the USEPA announced ...


  • Refrigerant leak detection is heavily regulated by government agencies

    Refrigerant leak monitoring in refrigeration and air-conditioning (RAC) systems and heating, ventilation and air conditioning (HVAC-R) equipment is very challenging, even for the most skilled HVAC-R technician. The leak could be well concealed from view in tubing, a system component, or in an operating or safety control component. With the Environmental Protection Agency (EPA) laws documented ...
