Hello, when did the activity of "Environment Friendly, Child Friendly, Double Good" begin? The environmental protection, baby-friendly and double-good activities started from 1992. "Environment-friendly, child-friendly, double-good activity" refers to a global activity initiated and organized by UNICEF, which aims to raise people's awareness of children's rights and environmental issues, encourage governments and all sectors of society to pay attention to children and environmental issues, and promote the development of environmental protection and child protection. This activity started from 1992 and was initiated by UNICEF in the same year after the United Nations Conference on Environment and Development. On the first Sunday of June every year, the "Environmental Protection, Child-Friendly, Double Good Activities" Day is celebrated internationally for one week.
