  • Greenhouse gas mitigation in the EU: An overview of the current policy landscape

    In 2009, the European Union (EU) pledged a unilateral greenhouse gas (GHG) reduction target of 20 percent below 1990 levels by 2020, rising to 30 percent if “other developed countries commit themselves to comparable emission reductions” (European Council 2009). The EU’s GHG target forms one pillar of a so-called 20-20-20 package that, in addition to the 20 percent GHG reduction, ...

  • Current status, problems and control strategies of water resources pollution in China

    The surface water of 10 major river systems across China has been under intermediate pollution with striking eutrophication problems in major lakes (reservoirs). More data from the Ministry of Environmental Protection of China showed that underground water in 57% of monitoring sites across Chinese cities was polluted or extremely polluted. Rural water pollution, the rising number of ...

  • Analysis of the current knowledge gaps in the implementation of the Water Framework Directive

    The general objective of the REBECCA project1 is to provide relevant scientific support for the implementation of the Water Framework Directive (WFD). The two specific aims of the project are, firstly, to establish links between ecological status of surface waters and physico-chemical quality elements and pressures from different sources, and, secondly, to develop and validate tools that member ...


  • El Niño/La Niña Update: Current Situation and outlook

    Despite warming of the Tropical Pacific Ocean up until June, the overlaying atmosphere largely failed to respond. As a result, ocean temperature anomalies along the equator have decreased over the past two months. Changes in the wind patterns in early-August brought some weak re-warming, but winds have now returned to near normal in the western Pacific, while the pattern of cloudiness has ...

  • Asbestos monitoring – what monitor should I be using?

    Asbestos is the name given to a group of minerals that occur naturally as masses of strong, flexible fibres that can be separated into thin threads and woven. These fibres are not affected by heat and do not conduct electricity. Asbestos is chemically, relatively stable. For these reasons, asbestos has been widely used in many industries.  These four types are classified as follows:  ...

  • Using Benthic Macroinvertebrates to Assess Ecological Status of Lakes Current Knowledge And Way Forward to Support WFD Implementation

    Directive 2000/60/EC, commonly known as the Water Framework Directive (WFD) has initiated achange in both the concept of water quality and its assessment throughout Europe. It has started a shift from the mindset of Europe’s water resource being a product which may be monitored chemically to ensure its suitability for human use to one that regards water as a heritage. A more holistic assessment ...
