Nitrous Oxide Emissions Respond Differently to No-Till Depending on the Soil Type
The practice of no-till has increased considerably during the past 20 yr. The absence of tillage coupled with the accumulation of crop residues at the soil surface modifies several soil properties but also influence nitrogen dynamics. view more (2008-10-23)
Tracing ultra-fine dust
Fine particle emissions have been the subject of heated debate for years. People who live near industrial plants see the smoke being discharged into the atmosphere and wonder how harmful it is. view more (2009-10-06)
Fuel Emissions From Marine Vessels Remain a Global Concern
Marine vessels are no longer resting in a safe harbor. The forecast for clear skies and smooth sailing for oceanic vessels has been impeded by worldwide concerns of their significant contributions to air pollution and greenhouse gas emissions that impact the Earth's climate. view more (2008-09-10)
Biodiesel could reduce greenhouse gas emissions
A CSIRO report released today confirms that using pure biodiesel or blending biodiesel with standard fuel could reduce greenhouse gas emissions from the transport sector. view more (2007-11-28)
Learning to trade in carbon dioxide
"You have to be well prepared to enter the emissions trading arena. Otherwise you'll run the same financial risks as on a conventional stock exchange," declares Franzjosef Schafhausen of the German ministry for the environment, who heads the working group on the national climate change program. Poor awareness of the implications of... view more... (2003-12-01)
Greenhouse gas from English streams
English chalk streams are less healthy than we thought and are potentially even contributing to global warming, said Dr Mark Trimmer at a Science Media Centre press briefing today. view more (2007-12-11)
Seabird Ammonia Emissions Contribute to Atmospheric Acidity
Ammonia emissions from seabirds have been shown to be a significant source of nitrogen in remote coastal ecosystems, contributing to nutrient enrichment (eutrophication) and acidification in ecosystems. view more (2008-09-23)
Ancient British bog provides clue to global warming
Analysis of sediments from a British bog suggest that methane emissions increased due to intense global warming around 55 million years ago. view more (2007-09-20)
Agricultural soil erosion not contributing to global warming, study shows
Agricultural soil erosion is not a source of carbon dioxide to the atmosphere, according to research published online in Science. view more (2007-10-26)
Carnegie Mellon researchers to curb CO2 emissions
Carnegie Mellon University's Chris T. Hendrickson and H. Scott Matthews along with Alex Carpenter and Heather MacLean of the University of Toronto challenge Canadian officials to take the lead in eliminating dangerous carbon dioxide emissions that fuel global warming. view more (2008-04-03)
Aerodynamic trailer cuts fuel and emissions by up to 15%
Creating an improved aerodynamic shape for truck trailers by mounting sideskirts can lead to a cut in fuel consumption and emissions of up to as much as 15%. Earlier promising predictions, based on mathematical models and wind tunnel tests by TU Delft, have been confirmed during road tests with an adapted trailer. view more (2008-04-18)
Boat tail reduces truck fuel consumption by 7.5 percent
An articulated lorry was driven for a period of one year with a boat tail (of varying length) and one year without a boat tail. The improved aerodynamics, depending on the length of the boat tail, resulted in reduced fuel consumption (and emissions!) of up to 7.5 percent. The optimum boat tail length proved to be two metres. view more (2009-11-06)
Clean fuels could reduce deaths from ship smokestacks by 40,000 annually
Rising levels of smokestack emissions from oceangoing ships will cause an estimated 87,000 deaths worldwide each year by 2012 - almost one-third higher than previously believed, according to the second major study on that topic. view more (2009-07-09)
Growth in the global carbon budget
Today the new Global Carbon Budget was launched simultaneously by Global Carbon Project co-chair Michael Raupach in France at the Paris Observatory, and in the USA at Capitol Hill, Washington by GCP Executive Director Pep Canadell. view more (2008-09-25)
Academy cautious over Energy White Paper
The Royal Academy of Engineering's Vice President, Mr Phil Ruffles FREng, today welcomed the publication of the Energy White Paper but cautioned that the targets for renewables, reduction in emissions and energy efficiency were all economically and technologically demanding. The Academy has been on record previously pointing out the immense... view more... (2003-02-24)
All the carbon counts
Cutting down forests for agriculture vents excess carbon dioxide into the air just as industrial activities and the burning of fossil fuels do. view more (2009-05-29)
Forests - just how absorbing are they?
Forests form an integral part of the Kyoto Protocol on climate change because they act as terrestrial "sinks" to soak up the carbon emissions that are contributing to global warming. Countries that have ratified the protocol can offset their carbon emissions quota by planting trees, either at home or in developing countries. But how... view more... (2003-03-13)
New research shows EU how to hit Kyoto target
High temperature superconductor (HTS) devices could help the EU reduce its CO2 emissions by up to 52 million tonnes, equivalent to 65 per cent of its Kyoto Protocol commitment. Teemu Hartikainen, Jorma Lehtonen and Risto Mikkonen from Tampere University of Technology, Finland have worked out how much European GHG emissions would be reduced if... view more... (2003-07-23)
Seeing the forest and the trees helps cut atmospheric carbon dioxide
Putting a price tag on carbon dioxide emitted by different land use practices could dramatically change the way that land is used - forests become increasingly valuable for storing carbon and overall carbon emissions reductions become cheaper, according to research presented today at the annual meeting of the American Association for the... view more...

Decline in uptake of carbon emissions confirmed
A decline in the proportion of carbon dioxide (CO2) emissions absorbed by land and oceans is speeding up the growth of atmospheric CO2, according to a paper published today in the US Journal: Proceedings of the National Academy of Science. view more (2007-10-25)
