  • Voluntary greenhouse gas reduction programs have limited potential

    The set of voluntary GHG programs we reviewed use outreach efforts to recruit program partners and reduce GHG emissions. We found the greatest barriers to participation were the perceived emission reduction costs and reporting requirements. We also found that it is unlikely these voluntary programs can reduce more than 19 percent of the projected 2010 GHG emissions for their industry sectors. ...

  • A greenhouse gas source of surprising significance: anthropogenic CO2 emissions from use of methanol in sewage treatment

    The impact of methanol (CH3OH) as a source of anthropogenic carbon dioxide (CO2) in denitrification at wastewater treatment plants (WWTPs) has never been quantified. CH3OH is the most commonly purchased carbon source for sewage denitrification. Until recently, greenhouse gas (GHG) reporting protocols consistently ignored the liberation of anthropogenic CO2 ...

  • Low emission l/P convertors for natural gas meet new environmental regulations

    Overview Low emission pneumatic controllers and overall carbon footprint reduction are today's hot topics for electro-pneumatic control systems. As shown in the chart below, pneumatic controllers have been viewed as a significant source of greenhouse gas emissions!. Since natural gas is often an abundant pressure source, it is common practice to tap this gas as the supply ...

  • How to compile a greenhouse gas emissions registry

    With the federal government debating the best way to reduce greenhouse gas emissions on a national scale, policymakers must also address the need to collect the emissions data necessary to ensure the success of US climate change policies. The first step in reducing emissions is to measure them. Without accurate and complete data on the sources of emissions and the amount they emit, the success of ...

  • Another source of methane release

    Mary Kang wasn’t even originally looking at methane emissions. The Princeton doctoral candidate was trying to get to the bottom of another issue: carbon dioxide escaping after being stored underground. During that research, she got to wondering about methane emissions from old oil and natural gas wells. What Kang, now a Stanford postdoctoral researcher, and other researchers found could be ...

  • Air Quality Permitting for a New Coal-Fired Power Plant: A Timeline

    The high price of natural gas and alternative fuels has made utility companies take a second look at coal as a cheap, plentiful fuel source. For a greenfield plant considering coal, the environmental considerations are significant but not insurmountable. This article discusses the air quality regulations and permitting requirements that must be addressed, from New Source Review to greenhouse gas ...

  • Greenhouse Gas Inventories and Wastewater Treatment Plants

    ABSTRACT A greenhouse gas inventory identifies the sources and quantities of GHG emissions from a facility or a larger organization. Several best practice standards exist that provide guidance for conducting GHG inventories for industrial facilities like a WWTP. Key considerations in a WWTP GHG inventory will include emissions associated with thefacility’s energy use as well as methane ...

  • Measurements and Standards to Support Increased Energy Efficiency and Reduced Environmental Impact

    “The world is facing twin energy-related threats: that of not having adequate and secure supplies of energy at affordable prices and that of environmental harm caused by consuming too much of it.” Daniel Hecker, economist, Bureau of Labor Statistics, July 2005 Buildings in the U.S. consume 72 percent of all electrical energy produced in this country. Emissions associated with ...

  • Decision support tree for management of peatlands and organic soils

    Peatlands store tremendous amounts of carbon. However, when they are drained and used – mainly for agriculture, grazing and forestry – peatlands become significant sources of greenhouse gas emissions. Peatlands drainage and peat fires are responsible for almost one-quarter of carbon emissions from the land use sector. This decision support tree was developed for the 2012 report, ...

  • CO2 absorption study in a bubble column reactor with Mg(OH)2

    CO2 from the combustion of fossil fuels is the largest source of greenhouse gas emissions in the USA. Recently, there has been a growing interest in economical processes for the separation and sequestration of CO2 emissions from flue gas. The goal of this study was to study the absorption characteristics of CO2 from a simulated flue gas using reclaimed ...

  • 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. ...

  • EPA Issues Final Tailoring GHG Permitting Rule

    EPA estimates that Title V permits would be required for over six million sources not now subject to the program. On June 3, 2010, EPA issued a final rule addressing greenhouse gas (GHG) emissions from stationary sources under the Clean Air Act (CAA). This controversial rule set thresholds for GHG emissions that define when permits under the New Source Review Prevention of Significant ...

  • Determination of greenhouse gas emission reductions from sewage sludge anaerobic digestion in China

    Sewage sludge is a considerable source of greenhouse gas (GHG) emission in the field of organic solid waste treatment and disposal. In this case study, total GHG emissions from sludge anaerobic digestion, including direct and indirect emissions as well as replaceable emission reduction due to biogas being reused instead of natural gas, were quantified respectively. The results indicated that ...

  • CO and CO2 - What`s the Difference

    It’s easy to understand why people confuse CO-carbon monoxide and CO2-carbon dioxide. The names sound the same, they both are colorless and odorless gases, and at high concentration, both can kill you. The media doesn’t help. Back in the old days, movies taught us that you could commit suicide by sticking a garden hose in your car’s tailpipe and window, then gunning the ...

  • Centralized water and wastewater treatment as a greenhouse gas producer in Finland

    Centralized water and wastewater treatment are key components of modern society but, at the same time, sources of greenhouse gas emissions. In this study, we carried out an assessment of the role of centralized water and wastewater treatment as a greenhouse gas producer in Finland, based on the existing literature and a questionnaire study. The aim of the study was to outline the significance of ...

  • EPA Proposes To Establish Minor New Source Review Requirements And To Disapprove Severable Portions Of SIPs

    On January 11, 2016, EPA published a Proposed Rule in the Federal Register proposing to establish Minor New Source Review permitting requirements for greenhouse gas (GHG) emissions and to disapprove severable portions of the State ...

  • Compost as a landfill cover material for the elimination of methane emissions

    Landfills, with about 40 - 60 Mio t emitted CH4 each year, are considered to be an important global source of the greenhouse gas methane. These emissions are especially caused by inadequate gas collection systems and uncontrolled emissions from old dumps and unauthorised open dumping. With traditional gas collection systems only 40 to 60 % of the produced gas can be collected and reused or safely ...

  • Canadian government announces pan-Canadian approach to pricing carbon pollution

    On 3 October 2016, the Canadian Government proposed its pan-Canadian approach to pricing carbon pollution. Canadian Prime Minister Justin Trudeau announced that provinces must adopt a carbon pricing scheme by 2018 or the federal government will impose a carbon price. Provinces and territories must decrease emissions in line with Canada's target of 30 percent below 2005 levels by 2030 and with the ...
