The Catholic Church is encouraging congregants to go to Confession, or "reconciliation services".
It is part of an initiative to ensure that the Catholic Church plays a role in tackling the climate crisis.
The lay-run campaign, called Journey to 2030, was launched last weekend in partnership with the Bishops' Conference and the Ecological Conversion Group, a volunteer group for young Catholics.
The initiative aims to "create a sense of urgency towards our ecological crisis and those suffering from its ill effects" as well as promote confession of environmental sins.
As a result, it has created a toolkit for church leaders to help Catholics confess their environment-related sins and is sending out its resources to parishes across the country.
Pope Francis said: "The earth, our home, is beginning to look more and more like an immense pile of filth. Many things have to change course, but it is we human beings above all who need to change. A great cultural, spiritual and educational challenge stands before us, and it will demand that we set out on the long path of renewal."
'The Journey to 2030' says it aims to support the Catholic Church and it's community to progress towards this 'long path to renewal', by providing the necessary resources to parishes and individuals in order to engage with the "urgent challenge of our ecological crisis".
