In 2009, the Chalk Urban Art Festival in Sydney took the theme of climate change. Artists created works on the pavement in Chapel St, Paramatta, responding to the subject, engaging people on the streets in the discussion. A big success, the festival returns to this working class neighbourhood in 2010, with a different theme. This is an excellent example of how climate change can be inserted as a theme into an existing festival, and of an effective engagement model using street art.
