Ecumenical Decade of Climate Justice Action

Moving Together in Ecological Metanoia for Transformation

The Decade, in one brochure

For ten years, churches around the world are acting together for climate justice, caring for people and for nature, and standing with those hit hardest. The founding brochure sets out why, and what it asks of churches.

About the Decade

A spiritual crisis. A decisive moment.

The climate emergency isn't only environmental. It's a call to faith and discipleship. For ten years, churches worldwide are choosing to act together: in repentance, in hope, and in justice for those who suffer most.

Ecological metanoia means a turning of heart and mind: repenting of the habits, economies, and powers that harm creation, and letting that change reshape how we live, worship, and act together.

Scripture does not place us above creation but within it: the Earth is the Lord's, we are kin to all that lives, and our wellbeing and its wellbeing cannot be separated.

"The Earth is the Lord's and all that is in it."
PSALM 24:1

"Bear fruit worthy of repentance."
MATTHEW 3:8

"But the Earth will be desolate because of its inhabitants, for the fruit of their doings."
MICAH 7:13

21 June 2025, Johannesburg, South Africa: People undertake a collective closing act of unity and commitment to urgent climate action, at the conclusion of a Pilgrimage Encounter with Creation – including the launch of an Ecumenical Decade of Climate Justice Action – at the 2025 Central Committee meeting of the World Council of Churches taking place in Johannesburg (South Africa) from 18 to 24 June 2025 on the theme ’Pilgrimage of Justice, Reconciliation, and Unity’.

The urgency

We're close to tipping points we can't undo. Indigenous Peoples, people living in poverty, and young people are hit hardest by climate change, despite contributing least to it. This Decade puts their leadership first.

The vision, 2025–2034

Six pathways guide the Decade: worship and theology, understanding the wider links, equipping churches, mobilizing together, advocating for change, and investing in local solutions.

Where this sits

The Ecumenical Decade sits within the WCC's Living Planet programme: work on water, food, energy, climate litigation, and ecological justice that began long before 2025. For these ten years, that wider work gathers under the Decade's umbrella as a season of shared commitment and celebration. It is part of a much longer journey: the WCC fellowship has advocated for climate and economic justice for generations, and the Decade carries that witness forward.

Ecumenical Decade of Climate Action Symbol

This symbol gathers the Decade's invitation into one living circle: moving together in ecological metanoia for transformation. It points us to a shared pilgrimage that centres the communities most affected, Indigenous Peoples and young people, and calls the whole Body of Christ to repent, repair, and rise in hope toward climate justice and an Economy of Life.

SYMBOL GUIDE

2026 THEMATIC YEAR

Climate and biodiversity: two crises, one calling

In 2026, churches confront climate breakdown and species loss together, not as distant issues, but as urgent tests of faith. This hits hardest where justice is already scarce: among people living in poverty, Indigenous Peoples, island nations, subsistence farmers, and the species disappearing around them.

 

"God saw everything that he had made, and indeed, it was very good."

GENESIS 1:31

KEY FOCUS AREAS

Learning from Indigenous wisdom and traditions of reciprocity. Ecological reparations through climate finance, fossil fuel divestment, and loss-and-damage support. Nature-based solutions rooted in community rights, not corporate greenwashing. And systemic change confronting unjust economies, through prayer, advocacy, and direct action.

2026 ACTIVITIES

Regional consultations gather bishops, lay leaders, and educators from every continent. The first Global Climate Fast anchors Lent in penitence and solidarity. Churches mark the UN International Day for Biological Diversity on 22 May, and take part in the Season of Creation from 1 September to 4 October.

WHAT 2026 WILL DELIVER

A global theological statement on climate and biodiversity justice. Regional frameworks tailored to local contexts. Worship resources, educational tools and advocacy materials for congregations. Faith-based submissions to UN processes. A network of regional ambassadors sustaining the Decade's work.

A call from the ecumenical, interfaith and eco-spiritual coalition of the global south

Ahead of the First Conference on Transitioning Away from Fossil Fuels in Santa Marta, Colombia, 24–29 April 2026, our broad coalition of Christian, ecumenical, interfaith and spiritual networks and organizations, particularly from the Global South, joins with firm resolve and prophetic intent in the call for a Fossil Fuels Treaty. We call on all people of faith, spiritual seekers and people of good will, as well as faith communities, to support this call with their signature and to join the work to make it a reality in their respective countries.
