Each year, World Environment Day celebrates the environment and encourages action to protect our fragile ecosystems. The 2019 theme was air pollution, a global emergency that causes around 7 million premature deaths every year. Since 1974, World Environment Day has become a global platform for inspiring action on critical environmental issues. In 2019, this momentum was maintained. With official celebrations hosted in China, the world rallied around a movement to “Beat Air Pollution”. This call to action inspired governments, cities, schools, businesses, individuals, civil society and faith-based organizations to adopt practical steps to combat one of the greatest environmental challenges of our time. By tapping into a growing public realization that air pollution must be tackled, World Environment Day 2019 galvanized people across the world to explore renewable energy and green technologies and make changes to their everyday lives to improve air quality. Thousands of events were organized to raise awareness of the solutions to air pollution. Almost 240,600 people took the Clean Air Pledge on the Indian e-commerce payment platform, Paytm. On the Chinese e-commerce giant Alibaba, 933 million green actions were logged across more than 20 apps.
