The International Ozone Day is an annual event that commemorates the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer. In the last three decades, the Vienna Convention and its Montreal Protocol have galvanized 197 nations to work together on phasing out ozone-depleting substances, thus protecting the ozone layer for this and future generations and contributing significantly to global efforts to address climate change.
International Coastal Cleanup (ICC) is a global event initiated by Ocean Conservancy (OC) in 1986. Its aim is to engage citizens to remove trash and debris from beaches and waterways all around world, identify the sources of debris, and change the behavioral patterns that contribute to pollution.
Every year on or around 22 September, people from around the world get together in the streets, intersections, and neighbourhood blocks to remind the world that we don't have to accept our car-dominated society.
