The themes covered in these agreements are very broad: biodiversity and nature protection, climate change, protection of the ozone layer, desertification, chemical and waste management, cross-border water and air pollution, environmental policy (including impact studies, access to information and public participation), work accidents, maritime and river safety, environmental responsibility. The guidelines for an AED are defined by the participating countries. The United Nations and the World Trade Organization are important intergovernmental organizations for forging and implementing agreements. National biosecurity contact points are being set up at the Science and Technology Council, the Vice-President`s Office and the Ministry of Water and Environment in Kenya, Tanzania and Uganda. In addition, countries have developed systems to deal with requests for the introduction of GMOs into the environment, a monitoring, inspection and enforcement mechanism, and a streamlining of the roles and responsibilities of the institutions concerned. Other institutions involved are plant health institutions, ministries of agriculture, health, trade and industry, National Standards Offices, National Agricultural Research Systems, etc. In all these areas, the Union is a strong supporter of international environmental action and cooperation and an active player committed to promoting the concept of sustainable development around the world. Most environmental problems are cross-border and often global and can only be effectively addressed through international cooperation. That is why the Lisbon Treaty stipulates that one of the main objectives of the EU`s environmental policy is to promote action at the international level to address regional or global environmental problems, and in particular to combat climate change. The EU is actively involved in the development, ratification and implementation of multilateral environmental agreements. Between 1857 and 2012, 747 multilateral agreements on the environment were concluded.  After the Intergovernmental Conference in Stockholm in 1972, the creation of international environmental agreements multiplied.  The United Nations has made MMAs popular, most MMAs have been implemented since 1972 at the United Nations Conference on the Human Environment (also known as the Stockholm Conference).
 The Stockholm Declaration was adopted by the 113 countries attending the conference and was the first major universal document in an environmental issue.  In addition, the main agreements on lighter reference evidence were grouped according to the structure of the situation plan, based on general environmental issues. The three main objectives of the EU`s 7th Environment Action Programme (2014-2020) have an essential international dimension: the protection, conservation and improvement of the Union`s natural capital, the transformation of the Union into a low-carbon, environmentally friendly and competitive economy, and the protection of EU citizens from environmental constraints and risks to health and well-being.
