  • Fluorinated greenhouse gases 2011

    Greenhouse gases covered by the UNFCCC Kyoto Protocol include amongst others, three groups of fluorinated greenhouse gases (the so-called 'F-gases'): hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). These F-gases typically have very long lifetimes in the atmosphere and high global warming potentials (GWPs). The European Union Regulation (EC) No 842/2006 on ...

  • Pesticide runoff from greenhouse production

    A research has been undertaken studying pesticide residues in water from greenhouses and the use of soils and filter materials to reduce such losses. The pesticides detected in water samples collected downstream greenhouses include 9 fungicides, 5 herbicides and 4 insecticides. 10 compounds from flower and vegetable productions were frequently found to exceed environmental risk levels, and with a ...

  • Motor transport, greenhouse gases and economic instruments

    Motorised transport is the generator of several forms of negative externality including the uncompensated emissions of greenhouse (global warming) gases. This paper looks at some of the underlying economic issues pertaining to policy-making designed to limit the extent of these externalities. It sets out the basic nature of the problem and outlines our knowledge of the link between the physical ...
