The Convention on Long-Range Transboundary Air Pollution (CLRTAP) was signed in 1979 to address the issue of transboundary air pollution in Europe. It aims to reduce emissions of air pollutants such as sulfur dioxide, nitrogen oxides, and volatile organic compounds.

The Montreal Protocol is an international agreement that aims to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs).

The MARPOL Convention (International Convention for the Prevention of Pollution from Ships) is an international agreement that aims to prevent pollution from ships, including air pollution. It includes regulations on emissions of sulfur oxides, nitrogen oxides, and particulate matter from ships.

The Kyoto Protocol is an international agreement that aims to reduce greenhouse gas emissions to combat climate change. It sets targets for developed countries to reduce their emissions of six greenhouse gases, including carbon dioxide, methane, and nitrous oxide.

The Stockholm Convention is an international agreement that aims to protect human health and the environment from persistent organic pollutants (POPs). POPs are chemicals that are resistant to degradation and can accumulate in the environment and in the food chain.

The Minamata Convention is an international agreement that aims to reduce mercury emissions and releases to the environment. It sets limits on mercury emissions from various sources, including industrial processes, mining, and waste incineration.

The Convention on Long-Range Transboundary Air Pollution includes protocols that address the reduction of emissions of sulfur dioxide and nitrogen oxides from industrial sources. These protocols aim to mitigate the effects of acid rain and other transboundary air pollution issues.

The Helsinki Convention is an international agreement that aims to protect the marine environment of the Baltic Sea. It addresses issues such as pollution from ships, oil spills, and eutrophication, and promotes cooperation among Baltic Sea countries to ensure the sustainable use of the marine environment.

The Euro Emission Standards are a series of regulations that set limits on emissions of pollutants from vehicles sold in the European Union and other countries. These standards aim to reduce air pollution from vehicles and improve air quality.

The Vienna Convention for the Protection of the Ozone Layer is an international agreement that aims to protect the ozone layer by controlling the production and consumption of ozone-depleting substances. It provides the framework for the Montreal Protocol, which sets specific targets for the phase-out of these substances.

The Basel Convention is an international agreement that aims to control the transboundary movement of hazardous wastes and their disposal. It sets guidelines for the environmentally sound management of hazardous wastes and promotes cooperation among countries to prevent illegal trafficking of hazardous waste.

The Rotterdam Convention is an international agreement that aims to control the trade in hazardous chemicals. It requires countries to obtain informed consent before importing or exporting certain hazardous chemicals, and it sets standards for the labeling and packaging of these chemicals.

The Clean Air Act is a comprehensive environmental law in the United States that aims to reduce air pollution from industrial sources, motor vehicles, and other sources. It sets emission standards for various pollutants, including sulfur dioxide, nitrogen oxides, and particulate matter.

The Gothenburg Protocol is a protocol under the Convention on Long-Range Transboundary Air Pollution that aims to reduce emissions of sulfur dioxide, nitrogen oxides, ammonia, and volatile organic compounds. These emissions contribute to acid rain and other transboundary air pollution issues.

The MARPOL Convention is an international agreement that aims to prevent pollution from ships, including air pollution. It includes regulations on emissions of sulfur oxides, nitrogen oxides, and particulate matter from ships, as well as regulations on the discharge of oil, sewage, and garbage from ships.
