Join the hundreds of thousands of Catholics who have already advocated for our common home ahead of the United Nations biodiversity conference later this year.

State of our common home

Our common home and common family are suffering. The climate emergency is causing rising seas, a warmer planet, and more extreme weather, all of which are devastating God’s creation.

At the same time, biologists estimate that we’re driving species to extinction at a rate of 100 to 1,000 times their usual rate. “We have no such right” (Laudato Si’ 33).

Our opportunity

Last year, more than 120,000 Catholics and 420 organizations, representing hundreds of thousands of people, united and signed the Healthy Planet, Healthy People petition. Those signatures were presented at the United Nations Climate Change Conference in Glasgow.

This year, at the United Nations Biodiversity Conference later, world leaders can set meaningful targets to protect creation. Ahead of that vital summit, it is our responsibility as Catholics to lift up the voices of the most vulnerable and advocate on their behalf. We must act now.

Our ask

Tackle the climate emergency and biodiversity crisis together

Promise no more biodiversity collapse

Ensure equitable global action, including support for those most affected

Protect and respect human rights, including the rights of Indigenous Peoples and Local Communities in climate and biodiversity action


When Catholics come together and live out our faith, amazing things happen. Just look at how Pope Francis’ Laudato Si’ has enlivened Catholics everywhere to care for creation.

Ahead of the Paris agreement in 2015, Catholics were leading the way, advocating for an agreement that limited warming to 1.5 degrees. Some said it couldn’t be done, but with the Holy Spirit leading the way, we did it!

We’re going to do it again this year.

Let’s be the change
