Heathcote resident and long-time environmental advocate Phil Smith has been nominated for an international award for an education program he runs in schools and universities.
The Speaking 4 the Planet program, which Mr Smith founded seven years ago, provides opportunities for young people to speak about their environmental concerns and about their future.
Mr Smith has been nominated for the Earth Prize International 2020, which is given by the Permanent Secretariat of the World Environmental Education Congress Network.
The awards ceremony will be on October 10 in Italy.
Mr Smith said the award recognised people who contributed ideas, actions or innovations which changed behaviours through lifestyle choices.
"The nomination would not have been possible without the support of many students, schools, teachers, councils and, in particular, the Sutherland Shire Environment Centre," he said.
The Speaking 4 the Planet program uses competition, such as speeches, theatre production, writing, creation of artworks, memes and TikTok, to focus attention on environmental issues.
"Our young people often show great insight and deep connection with the environment, even at a global scale," Mr Smith said.
"Speaking 4 the Planet has enabled many to speak, act, and draw on their passions and beliefs. Youth voices matters."
