  • 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 ...

  • Gas Hydrate Breakdown Unlikely to Cause Massive Greenhouse Gas Release

    The breakdown of methane hydrates due to warming climate is unlikely to lead to massive amounts of methane being released to the atmosphere, according to a recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester. Methane hydrate, which is also referred to as ...

  • How California’s greenhouse gas laws can better serve disadvantaged communities

    Environmental justice advocates are working to ensure the state’s efforts to combat climate change benefit everyone — and the lessons can be applied nationwide. It was a time of year that should have been perfect. Warming temperatures marked Southern California’s gentle return to spring. The grass had shifted from drab to glowing green.

  • Technology choices in scaling up sanitation can significantly affect greenhouse gas emissions and the fertiliser gap in India

    Nearly 800 million people in India lack access to adequate sanitation. The choice of technology for addressing this need may have important sustainability implications. In this study, we used life cycle assessment to compare environmental impacts and nutrient recovery potentials of four different options for providing everyone in India with access to improved sanitation: (i) centralised ...

  • Study: Climate change could overwhelm U.S. electrical grid

    Climbing temperatures associated with global warming could wreak havoc on the U.S. electrical grid, according to a new study on the economic and social costs of climate change. Published last week in the scientific journal Proceedings by researchers at the University of California-Berkeley, Stanford, and University of Michigan, the study says the country will need to spend at least $180 billion ...

  • Waste materials are an underused resource the construction of Europe`s roads

    Recycled waste material could play a major role in the construction of roads in Europe, bringing both environmental and economic benefits. A new study proposes a scenario where 50% of the asphalt for Europe's roads consists of recycled materials, leading to significant reductions in costs, energy use and greenhouse gas emissions. According to the European Waste Framework Directive, there is a ...

  • Meeting emission control through improved actuation

    Introduction Reducing fugitive emissions, particularly methane, is a major priority in the fight against climate change. Although valves and actuators have been the focus for reduction efforts because valve leakage accounts for more than half of total fugitive emissions, the problem is mainly old valves that weren't designed using the latest materials and technologies. New technologies can ...
