  • 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 ...

  • Oil shale is not a viable fuel source - Study

    While many are celebrating the end of the 'Peak Oil' concerns because of abundent new sources of oil in shale deposits, a true accounting for all economic and environmental costs to exploit this energy source suggests it may not be a viable proposition at all. Scientists' best estimates of the Energy Return on Investment (EROI) of oil shale suggest it is very inefficient compared to conventional ...

  • Analysis of key trends and drivers in greenhouse gas emissions in the EU between 1990 and 2014

    1 GHG emissions in 2014 compared to 2013 1.1 Summary (last year) Total GHG emissions (excluding LULUCF) decreased by 185 million tonnes, or 4.1% compared to 20132 to reach their lowest level in 2014 (4282 Mt CO2 eq.). This significant decrease in emissions in 2014 came with an increase in GDP of 1.4 %. This resulted in a lower GHG-emission intensity of GDP in the EU ...

  • Annual European Union greenhouse gas inventory 1990–2012 and inventory report 2014 - Submission to the UNFCCC Secretariat

    BACKGROUND INFORMATION ON GREENHOUSE GAS INVENTORIES AND CLIMATE CHANGE 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 t-2 for emissions and removals within the area covered by its Member States (i.e. domestic emissions taking place within its ...

  • Perspectives on greenhouse gas emission estimates based on Australian wastewater treatment plant operating data

    Primary operating data were collected from forty-six wastewater treatment plants (WWTPs) located across three states within Australia. The size range of plants was indicatively from 500 to 900,000 person equivalents. Direct and indirect greenhouse gas emissions were calculated using a mass balance approach and default emission factors, based on Australia's National Greenhouse Energy ...

  • Annual European Union greenhouse gas inventory 1990–2014 and inventory report 2016

    ES.1 Background information on greenhouse gas inventories and climate change 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 between 1990 and the current calendar year (t) minus two (t–2), for emissions and removals within the area covered by its Member ...

  • Impact assessment of multiple uncertainty sources on high flows under climate change

    This paper aims to investigate the uncertainty ranges of high flows under climate change in Jinhua River basin, eastern China. Four representative concentration pathways (RCPs), three global climate models (GCMs), 10 downscaling parameter sets and three hydrologic models are applied to simulate future discharges. Changes of annual maximum discharges are assessed for the baseline period ...

  • Vulnerability of Mexico City's water supply sources in the context of climate change

    In the context of growing urbanization and climate change, the issue of how to best secure and increase future water supply in developing countries is key. To support informed decision-making in Mexico City, a comprehensive study was conducted to assess the potential effects of climate change and the vulnerability of water sources. The infrastructural, environmental and administrative factors ...

  • Regulation of greenhouse gases under section 115 of The Clean Air Act

    Section 115 of the Clean Air Act, among the various options under the current act, may offer EPA the most effective, flexible, economically reasonable, and legally supportable means by which to regulate greenhouse gas emissions. The authors argue that Section 115, the section explicitly crafted to address international air pollution, has the potential to provide an appropriately flexible path ...

  • World Bank: Promote clean energy sources to end energy poverty

    On July 16, 2013 the World Bank agreed to support universal access to reliable modern energy and limit the financing of coal-fired power plants to rare circumstances in an effort to address climate change concerns. As the Bank and other development agencies work to provide energy access to ...

  • How to better manage refrigerant gases in order to reduce greenhouse gases (GHGs)

    Carbon emissions reporting requires detailed monitoring record keeping of emission sources. Reducing a company's CO2 emissions has an impact on climate change. Carbon reporting needs to be approached in a structured organized way. Doing so in this way is known as carbon management. Carbon (CO2) Emissions Reporting: It's the law. In many countries, carbon emissions are required by law to be ...

  • A shale gas revolution?

    MIT report shows prosperous shale gas market could hurt future R&D, if we let it. By Vicki Ekstrom, Joint Program on the Science and Policy of Global Change, MIT Shale gas - a resource that has grown significantly in just the last few years to one-quarter of the domestic gas supply - is cheaper and involves fewer emissions than traditional coal or oil. But recent ...

  • Dry regenerable sorbents for the separation and capture of CO2 from large point sources

    The combustion of fossil fuels generates large quantities of carbon dioxide (CO2), a greenhouse gas most likely to influence global warming and climate change. Large stationary sources that include coal-based electric generating stations are plausible targets for the removal of CO2. Chemical absorption of CO2 is viewed as one option that could be applicable ...

  • The tailoring of greenhouse gases to the clean air act – challenges for PSD and title v permitting ahead?

    In anticipation of the promulgation of Clean Air Act (CAA) regulations to control greenhouse gas (GHG) emissions, EPA published the proposed PSD and Title V GHG Tailoring Rule. The proposed GHG Tailoring Rule was published in the Federal Register on October 27, 2009 and has a 60-day public comment period; thus comments are due by December 28, 2009. The proposed GHG Tailoring Rule attempts to ...

  • Landfill Gas Use Trends In The United States

    MOST PEOPLE think of landfills as a necessary evil at best, but our current primary method of waste management generates a by-product with significant energy value - landfill gas (LFG). Collection and control of LFG results in significant reductions in greenhouse gas (GHG) emissions. With the greater focus on climate change, a burgeoning market for GHG emission offsets is emerging and landfills ...

  • U.S. Natural Gas Exports: Friend or Foe?

    U.S. natural gas production is booming. According to the Energy Information Administration (EIA), production grew by 23 percent from 2007 to 2012. Now—with production projected to continue growing in the decades ahead—U.S. lawmakers and companies are considering exporting this resource internationally. But what are the climate implications of ...

  • Case study - Amine tail gas treatment

    COVERING YOUR TAIL GAS The discovery of new shale formations throughout the world and the development of new drilling technologies have increased natural gas production and prompted government agencies to instigate tighter air-pollutioncontrol regulations on processing operations.

  • Shale Gas: Time to look before we leap any further

    Shale gas is a game-changer for global energy supply. It is already transforming the U.S. energy outlook, and is expected to deliver over 40% of domestic gas production by 2025 (Figure 1). Other countries and regions, notably Europe and China, may soon follow suit, in a repeat of the early 20th century oil rush. Opinion is bitterly divided, however, over the environmental risks and benefits of ...
