Global environmental issues affect everyone and agreements need to support from all nations
The UN has/is trying to manage many of the world's environmental issues, but has seen varying success
Over time, numerous other agencies, IGOs and agreements have come into being that deal with particular issues and environmental governance
Montreal Protocol (1987)
In 1974, a group of scientists suggested that chemicals used in products such as aerosols, packaging and fridges, could deplete the ozone layer and increase harm to humans and wildlife on earth
By 1985, the ozone depletion theory was proven, when a 'hole in the ozone layer' was discovered over Antarctica
An agreement was signed two years later and entered into force in 1989
Six amendments and adjustments have been made since then
Montreal Protocol agreement:
The agreement regulates the production and consumption of nearly 100 ozone depleting substances (ODS), such as CFCs, halons, HCFCs, methyl bromide and HFCs
The agreement has been successful in reducing the global emissions of ODS and restoring the ozone layer, as well as contributing to climate change mitigation
Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES):
CITES is a multilateral treaty to protect endangered plants and animals from the threats of international trade and organised by IUCN (International Union for Conservation of Nature)
Legal trade in wild animals and plants (alive or dead) is worth an estimated US$220 billion each year
Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES):
lists 40,000 species of animals and plants, whether traded as live specimens, fur coats or dried herbs
It regulates trade through a system of permits and certificates issued by national authorities
However, protection of species from illegal trade is difficult to manage as goods typically cross borders between countries which requires international cooperation and is expensive to monitor
