In 2012, Key and his fans from Korea, China, Japan, Taiwan, Singapore, Thailand and seven other countries donated 2.12 tons of rice to World Vision, which was able to feed 17,000 undernourished children and elderly among 11 cities. Later on September 23, 2014, Key's birthday, fans raised a total of 2 million won and established a well in Cambodia, and was also used as medical aid for poor children. In 2015, Key posted on his Instagram account encouraging viewers to help the citizens in Nepal after its earthquake, and sent moral support. In the same year, Key collaborated with designer Ko Taeyong and sold sweatshirts depicting his dogs. All revenue (approximately 12.5 million won) were later donated to the Animal Freedom Union. In 2016, Key along with groupmate Taemin and other artists from SM Entertainment took part in the "Make a Promise" campaign organised by UNICEF and Louis Vuitton, whereby 40% of the proceeds were donated through UNICEF to the children in need.
