The Keep Sweden Clean litter-picking days are underway for the 22nd consecutive year, with nearly 600,000 participants registered, about half a million of whom are children, making it the country's largest environmental initiative for young people. The event runs until the end of May. In Arjeplog, nearly 90 percent of all children between 1 and 16 years old are taking part, giving the municipality the highest participation rate in the country relative to its child population.
This calculation is based on the percentage share of children aged 1-16 in each municipality who are registered for the litter-picking days, compared to the total number of children in the municipality, according to Keep Sweden Clean, the source for the participation data. According to SVT Nyheter, a nine-year-old student encouraged children who are not participating to go out and pick up litter. The specific environmental impact or amount of litter collected this year has not been disclosed, and it is unclear how participation rates compare to previous years or what types of litter are most commonly targeted.
