St. Columbans Mission Society from Australia offers a Season of Creation for use in Roman Catholic parishes.

See also their page on Peace, Ecology & Justice for a variety of resources.

Here is the link for the information on the 2014 series.

About the 2014 materials, they say: This resource explores the existing Catholic Lectionary to help us remember God’s seamless gift of Life in all Creation – people within the natural world. It grows out of an Adelaide based ecumenical work led by Scripture scholar Dr. Norman Habel.

Called ‘A Catholic Season of Creation’ it has four

 leaflets for the four Sundays of September. It explores the Sunday Lectionary and the gifts of forests, land, wilderness and water to help us hear the voice of earth as a voice of God.

Our Sunday worship is a great place to start if we
 want to grow a better recognition of the natural world in God’s plan of salvation in Jesus Christ. Linking the insights of ecology with Scripture deepens our appreciation of the way God acts in our lives.
