The eutrophying effects resulting from increased deposition rates of reactive nitrogen to ecosystems are a major problem in the context of long range transported air pollution. Therfore, one focus of the related effects oriented research is to improve knowledge on time- and area-depending effects for modelling purposes.

There is indicative evidence that anthropogenic greenhouse gas emissions are leading to changes in the global climate. The consequences for human beings and the environment as predicted by experts will vary from region to region. Precipitation levels are expected to increase in some regions, and decrease in others.

As a Party to the United Nations Framework on Climate Change, since 1994 Germany has been obliged to prepare, publish and regularly update national emission inventories of greenhouse gases. By adopting the Kyoto Protocol in 1997, the international community of nations reached agreement, for the first time ever, on binding aims and implementation instruments for global climate protection.

On 30 December 2002 Regulation (EC) N° 2150/2002 of the European Parliament and the Council of 25 November 2002 on waste statistics1 entered into force. It was last amended by Regulation 574/2004 of 23 February 2004.

Fluorinated greenhouse gases (GHG) are used in a multitude of applications to date. Next to perfluorinated compounds (e.g. CF4, C2F6 or SF6), especially the fluorinated hydrocarbons (HFC) are of relevance by means of volume. HFCs represent the special focus of this study.

Despite of the widely accepted but general goal of the Climate Convention to prevent dangerous human interference with the climate system, its interpretation with regard to further international commitments is still pending. This situation gives reason for investigations towards reasonable specifications of the Convention’s ultimate goal.  

This Handbook and the associated research report outlines a methodological concept for the procedure for selecting cost-effective combinations of measures in accordance with the Water Framework Directive, including the sample application thereof. The starting point for the methodology developed in this project is the inventory required by the end of 2004 under the Water Framework Directive.

The purpose of this document is to summarize the results of an international round of testing and research aimed at developing and optimizing an amphibian-based screening assay for thyroid axis disruption.

Society places a high value on protecting children. For that reason, the demand is repeatedly made that children’s particular vulnerability be given special consideration when evaluating environment-related health risks and deriving limit values. Current regulatory practice often attempts to do this in a relatively schematic way, in the form of safety factors.

This report reviews the EU Directive’s guidelines for a model’s quality assessment, and examines specific model quality criteria, that may be used for model accuracy assessment according to the intentions of the EU directives. Several model accuracy measures are tested utilizing a one-year simulation with the chemical transport model REM-CALGRID (RCG).

Due to the predicted growth rates for air traffic and the intended capacity extensions at many international airports, economic instruments have become more important. This study examines how LTO-charges, which are differentiated according to aircraft-noise emissions, can stimulate incentives for airlines to use less-noisier aircraft.
