1. 26 states sign the Antarctic treaty; exploitation of natural resources is banned for 50 years. A legally binding (under civil law) Protocol on Environmental Protection is part of the treaty, containing the goal of conserving biodiversity and the ecosystem in the Antarctic. The Protocol is embodied in German law with an Act Implementing the Protocol of Environmental Protection to the Antarctic Treaty.

  2. The Agreement on the Conservation of Small Cetaceans of the Baltic and North Seas (ASCOBANS) was concluded in 1991 under the auspices of the Convention on Migratory Species (CMS or Bonn Convention) and entered into force in 1994. In February 2008, an extension of the agreement area entered into force which changed the name to “Agreement on the Conservation of Small Cetaceans of the Baltic, North East Atlantic, Irish and North Seas”. ASCOBANS covers all species of toothed whales in the Agreement Area, with the exception of the sperm whale.

  4. Hosted and organised by the Stockholm International Water Institute (SIWI), the World Water Week in Stockholm has been the annual focal point for the planet’s water issues since 1991.

  5. 25 years ago, the German Arctic Station in Svalbard was officially opened by the former directors of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Prof. Gotthilf Hempel and Dr Rainer Paulenz, as well as the BMBF State Secretary, Mr. Bernd Neumann. The Koldewey Station originated from a joint cooperation with the Norwegian Polar Institute and the Norwegian operating company Kingsbay along with sponsorship from the Federal Ministry of Education and Research. It was the first non-Norwegian station in Ny Ålesund operating all year round. In 2003, the stations "Koldewey" and "Rabot" were merged into a modern German-French Community Station AWIPEV. In 1988, the AWI started its first seasonal research work in Ny Ålesund, Svalbard. The scientific motivation was the exploration of the arctic ozone layer, especially in winter and spring, which required staying there throughout the winter. The establishment of the station and the good working conditions locally allowed for the quick expansion of the scientific spectrum of tasks to include atmosphere-chemical, biological and geo-physical topics. To this day, the topic of climate change and its impact on life in the Arctic is of central importance for the observatories and project work conducted at AWIPEV station.

  6. The "ABT Summer", carrying 260,000 t oil, catches fire off the coast of Angola.

  7. The Vienna Convention is embodied in German law with this ordinance. Such regulations have resulted in cuts of over 40% relative to 1986 in CFC use, 95% in the case of Germany.

  8. The "Haven" catches fire and sinks in the Mediterranean, carrying 143,000 t crude oil.

This represents the breakthrough for chlorine-free paper, which gradually becomes a printing standard.

  12. The Deutsche Bundesstiftung Umwelt DBU is one of Europe's largest foundations and promotes innovative and exemplary environmental projects.

  13. The Espoo Convention on Environmental Impact Assessment in a Transboundary Context (EIA) stipulates the obligations of Parties to assess the environmental impact of certain activities at an early stage of planning. It also lays down the general obligation of States to notify and consult each other on all major projects under consideration that are likely to have a significant adverse environmental impact across boundaries. The Espoo Convention entered into force on 10 September 1997.

  14. The Gulf War oil spill was one of the largest oil spills in history, resulting from the Gulf War in 1991. The apparent strategic goal was to foil a potential landing by US Marines. It also made commandeering oil reserves dangerous for US forces as visibility and movement were inhibited. The immediate reports from Baghdad said that American air strikes had caused a discharge of oil from two tankers. Coalition forces determined the main source of oil to be the Sea Island terminal in Kuwait. On January 26, three US F-117 fighter-bombers destroyed pipelines to prevent further spillage into the Persian Gulf. Several other sources of oil were found to be active: tankers and a damaged Kuwaiti oil refinery near Mina Al Ahmadi, tankers near Bubiyan Island, and Iraq's Mina Al Bakr terminal.

  15. Bird of the Year 1990 is the Grey Partridge (Perdix perdix).
