EcoJesuit has launched its newest campaign, 'Letters to the Earth', inviting communities, schools, and parishes to share their voices through letters and creative reflections calling for climate justice in the lead-up to COP30, the UN climate summit taking place in Belém, Brazil from 10–21 November 2025.

At the heart of this initiative is you. Everyone is encouraged to write a personal letter, create artwork, or share another imaginative response expressing your concerns, hopes, and commitments for the future of our common home.

To support your participation, EcoJesuit has developed digital handbooks for different age groups. These introduce ecological and theological themes from Laudato Si’ and Laudate Deum, with reflection questions, scripture-based meditations, and real-life case studies from Jesuit ministries worldwide. The handbooks are freely available to download on the EcoJesuit website here.

The initiative forms part of the wider Jesuits for Climate Justice: Faith in Action at COP30 campaign. This global mobilisation is calling on world leaders to:

- Cancel the debts of poorer countries

- Ensure a just transition to renewable energy

- Adopt sustainable, agroecological food systems

In May 2025, the Jesuits in Britain backed the global Jesuit campaign for climate justice ahead of COP30. In June, a delegation from Jesuit Missions attended the UN climate talks in Bonn, which focused on the technical preparations for COP30.

This shared journey continues in many ways, including through the work of the Laudato Si' Research Institute at Campion Hall, Oxford, which develops an “integral ecology” paradigm to promote hope-filled, transformative action.

This is an important year for climate justice. By connecting Jesuit works across continents and amplifying youth voices, the Letters to the Earth campaign seeks to inspire a global ecological conversion grounded in faith, sustainability, and justice.
