Anglican Communion Environmental Network (ACEN)
The Anglican Communion Environmental Network (ACEN) is a global network within the Anglican Communion that encourages churches, dioceses and provinces to respond faithfully to environmental challenges. Grounded in the Fifth Mark of Mission — ‘to strive to safeguard the integrity of creation and sustain and renew the life of the earth’ — ACEN promotes care for creation as an essential expression of Christian mission and discipleship. The network supports environmental education, advocacy, sustainable practices and climate action, while facilitating the sharing of resources and experiences across the Anglican Communion.
Chair of ACEN
The Chair of ACEN is the Most Revd Marinez Rosa dos Santos Bassotto, Primate of Brazil and Bishop of the Amazon.

The Season of Creation
The Season of Creation is an annual global celebration that unites Christians of all traditions in prayer, reflection and action for the protection of God’s creation. It runs from 1 September (Feast of Creation/World Day of Prayer for Creation) to 4 October (Feast of St Francis of Assisi).
The theme for 2026 is ‘Living Water’, based on Ezekiel 47:9,12. Get the celebration guide and ecumenical prayer service, available in several languages.
The Feast of Creation in Christ
The Feast of Creation in Christ is celebrated on 1 September or the first Sunday of September. It is an ecumenical celebration that gives thanks for God’s creation and proclaims Christ as the one through whom and for whom all things were made (Colossians 1:15–20).
The celebration’s roots lie in the Orthodox Church’s observance of a Day of Prayer for Creation, established by the Ecumenical Patriarchate of Constantinople in 1989. The feast has now been included in the Revised Common Lectionary.
The Communion Forest
The Communion Forest is an Anglican Communion initiative to significantly increase tree-growing and ecosystem conservation, protection and restoration activities around the world. It also aims to deepen care for creation within the life of the Church and its members.
It is a practical, spiritual and symbolic response to the environmental crisis, and an act of Christian hope for the well-being of humanity and all God’s creation.
Lungs of the Earth campaign
‘Lungs of the Earth’ is a call for environmental action and advocacy. It invites Anglicans to restore and protect God’s world, with a particular focus on three vital ecosystems that act as the planet’s natural lungs: oceans, forests and ice caps.
Due to environmental damage, these lungs of the earth are at risk, with huge implications for people and planet.
