The Political Context of ICP Modelling & Mapping
At the Conference on Security and Cooperation in Europe, concluded 1975 in Helsinki, European States recognized the increasing threat and international nature of air pollution. The participating states affirmed the aim to cooperate more closely in the fields of research and development, and the implementation of pollution control strategies, when they adopted the Final Act. (
The goal of the Convention is to control air pollution and its effects and to develop an extensive programme for the monitoring and evaluation the long-range transport of air pollutants. The Convention calls for the exchange of information and the coordination of research activities in order to develop control strategies to combat air pollution. It specifies, besides others, the need to initiate and cooperate research and development of monitoring and measuring air pollutants. It also calls for improving models for a better understanding of the transmission of air pollutants, and the effects of sulphur compounds and other major air pollutants on human health and the environment. Since 1984, eight protocols for controlling sulphur, nitrogen oxides, volatile organic compounds, heavy metals, persistent organic pollutants and abating acidification, eutrophication and ground-level ozone have been adopted under the Convention.
In 1988 the Working Group on Effects (WGE) founded the Task Force on Mapping, later renamed to ICP Modelling and Mapping of Critical Loads & Levels and Air Pollution Effects, Risks and Trends (ICP Modelling & Mapping) to develop an effects-based approach for implementing the Convention. The ICP Modelling & Mapping cnducts research jointly with other ICPs and the Task Force on Health Aspects under the WGE to support the LRTAP Convention goals of monitoring and controlling trans-boundary air pollutants.
The ICP Modelling & Mapping particularly fulfils the requirements from Article 7(d) and 8(f) of the Convention (
