Greenpeace activists protesting against Mattel, the manufacturer of Barbie, in front of toyshops in Helsinki, Finland.

Greenpeace investigators used forensic testing to reveal that the packaging for Mattel's Barbie dolls comes from Indonesia's rainforests. They also used a combination of investigation, mapping data and traced company certificates to show that Mattel, along with other toy companies including Disney, are using packaging produced by Asia Pulp and Paper (APP). APP has been exposed many times for wrecking Indonesia's rainforests to make products such as packaging.
